Installing the "Ebay Intake"

[Plays_with_Toys]

Everyone has seen these things on ebay. The $20 ebay intakes.

A thread on NASIOC (click here) (http://forums.nasioc.com/forums/showthread.php?t=706723&page=1&highlight=ebay+intake) shows that a 10hp and 10ft/lb of torque increase in the low-midrange RPMs can be had. So when one showed up for dirt cheap, I jumped on it, and went to install it.

Ok, first of all, these are designed for "98-99" legacy's, from the titles on ebay. I haven't yet found a real difference between these newer engines and my 1996 2.2. There is one thing though about this intake. It has (2) vacuum lines coming off of it, and the stock intake has (3).

List of things you will need:
1/2" T connector
1/2" elbow with male threaded end
3" to 3" flexible coupling (rubber) (the metal clamps are included)
1' of 3/4" hose (*** I did not need this, but the insurance of having this hose is worth the extra $1.30)
Total cost of extra materials should be around $12.

First of all, here's the engine bay stock:

Take out the stock intake piping, and remove the MAF/top half of the airbox (you'll need to unpluge the MAF). There are 4 vacuum lines you will need to disconnect. Two on the back, one near the bends that lead to the intake manifold. Just disconnect it at the PCV junction. The last one is the biggest hose that connects near the MAF. Here is what it should now look like:

https://sl-i.net/FORUM/images/imported/2005/11/img20116ceth-1.jpg (http://img217.imageshack.us/img217/3272/img20116ce.jpg)

Next I did a test fit to see how everything would bolt together. I could tell that some pushing and shoving would be needed until the rubber couplers were in the right position for the tubing to go in correctly.

The 3" to 3" couple is too larg for both the intake piping and the MAF pipe. You should notice this immediately, however, because of its soft rubber, it will contract down and around each pipe with no problem. You will need to drill a 1/2" hole in the middle of the coupler. Use small drill bits leading up to the 1/2" bit. The rubber is strange to work (it molds itself around the bit, make sure to work the bit in and out until you can get a round hole.

https://sl-i.net/FORUM/images/imported/2005/11/img20175ogth-1.jpg (http://img217.imageshack.us/img217/6773/img20175og.jpg)

Next insert the elbow so that the threaded end is out. Make sure it fits snug, and does not protrude too deeply into the tubing itself. (you can remove this now for an easier install later)

Install the included blue vacuum lines where the PCV valve line you took off went (its a tight fit, since the included lines are 3/8" and all the stock are 1/2") Install the T where the two valve cover lines come up, and install another blue line on the T as well (another tight fit)

http://img127.imageshack.us/img127/6092/img20152pa.th.jpg (http://img127.imageshack.us/img127/6092/img20152pa.jpg)

Use the metal clamp that is on the end of your stock piping to clamp the blue coupler included with the kit to the intake manifold. The other larger metal clamp included with the kit should go around the larger diameter piping of the intake. Also connect the 3" coupler at the other end. I tried to keep this coupler as close to the edge of the piping as possible. Thread the white elbow into the 3/4" tubing for the Idle Air Bypass. It should thread in tightly.Then plug this into the hole you drilled. Attach the maf and clip it onto the filter box, then tighten down the coupler. Again, move the intake around until the fitment is right. Plug in the remaining blue vacuum lines to the intake, reset the ECU (pull negative battery cable, hold down brake for 15-25 seconds, reattach battery cable) and enjoy.

So as for performance... A little louder than a simple snorkusectomy, and well, no real power improvement. I haven't reset the ECU yet though, so I will do that today and repost my results. If anything, its engine bling for cheap.

***Update: I reset the ECU after making this post, and let 'er rip. New impressions... Holy torque change batman. Where the car might bog down a little from a stop light, the car doesn't bog, even on a rough shift it'll add a kick of acceleration. There is some better get up and go between 2600 and 4000 rpms. Now the improved acceleration is only slight, but it is a perceptable change for the better.

EDIT: Update 2007- check the welds on your bungs to make sure they are still intact upon receipt of your intake and you should probably check everytime you do a new air filter. Mine has started to seperate, I plan to patch it up with some JB weld/quick steel. No biggie, but something to check for.

All it does is replaces the intake tubing, its actually proven a performance increase by dyno testing ;)

[Tokio]

lol, ok...

well, ill try to be nice and say "maybe his dyno was high that day" or " maybe he enjoys attention"... at any rate, my personal dyno experience would tend to disagree with the "ebay" intake...as with all other bargain-parts from there...

but, by all means... by the intake, knock yourself out... maybe gain a couple of horsepower and tell everyone how much your car pulls and tears off the line... :lol:

id say more, but i would HATE to suffer the same fate as Tris.

[Wiscon_Mark]

Jesse, c'mon, the intake was a direct comparison to an expensive aftermarket one, the variables were few and far between...

[Reason]

Tokio where are your numbers? Let me guess you don't have any you can show us. No problem, everyone has an opinion. The difference between This and the rest of the forum is that Tris couldn't express himself and opinions in a respectful and proper way. I talked to Tris and his ban was lifted. Theres no problem with disagreeing with anyone just don't be a disrespectful douchebag. Anyone can be disrespectful, it takes a mature adult to conduct themselves the proper way on a public forum.

id say more, but i would HATE to suffer the same fate as Tris.

Tokio, I didn't claim incredible gains. There was a small but noticeable difference. A clear difference is the fact that my torque curve changed, because my car can actually pull from 40mph in 3rd gear almost as strongly as 40mph in 2nd gear. Before I had to shift around 48mph or else 3rd gear was a dog. Also, like I said, rough shifts seem to be soaked up. This could be the intake, or it could be better flow going through the IAB with where I placed the air take in for that system. I don't know.

I personally would like to see your results, or heck, someone who can say you actually installed one. Its easy to knock something when you haven't tried it. When you're dealing with these low power N/A legacy's, the mods don't amount to much, but they are as much fun for me to put together as they are to enjoy them when I drive/ walk up to my car to go driving.

[Perdue]

The intake was also compared to stock. It gained 10whp over stock, and was noteably better than other aftermarket intakes. I believe the dynos were all done on the same day, so the dyno "running high" isn't an excuse.

And using an ebay part makes you a ricer? Even when it provides PROVEN results? As stated, it's easy to bash something when you haven't tried it. Then intake works, and it's been proven by someone who isn't even affiliated with the company making it. The $20 ebay intake actually works better than most other aftermarket intakes, so why is it rice? Why still so skeptical, Jesse?

And very nice writeup, PWT. I wish I still had my stock airbox, because I'd probably be getting rid of the GPMoto short ram right now.

Bustin' out the Shakespear/Intake metaphors yo

[Wiscon_Mark]

:lol: @ Lee

So you can ask why this intake is so much cheaper than the other aftermarket intakes?

Well, there's several reasons:
No Brand Name
No Filter
Semi-universal (not exact fit for legacy)

There's also several reasons I can think of that it would be better for performance:
Wider Diameter (more airflow)
Got rid of the ribs from the stock intake (less turbulence)

you can dispute these things, but the dyno doesn't lie.

[gil_ong81]

really, man, give it a chance. just cos it's a no-name ebay part doesn't mean that it's automatically a piece of junk.

[Plays_with_Toys]

Mark, I think the improvement comes from the larger piping, and the smoother bends. If you look at the stock, the last bend that goes into the intake manifold is a very tight/ugly bend.


One thing I've noticed is that when my car is only partially warmed up, the torque is more present than when it is fully warmed up. I've been researching about thermostats, but it sounds like the cooling system on subarus are finicky, and since cooling issues is what killed my last vehicle, I don't really know if I want to tackle this idea, and risk a car that hasn't given me hardly any problems, over a small gain.

[Wiscon_Mark]

Mark, I think the improvement comes from the larger piping, and the smoother bends. If you look at the stock, the last bend that goes into the intake manifold is a very tight/ugly bend.

yeah, goes along with the turbulence idea ;)

[shazapple]

Does the intake extend into the fender? Maybe buying a rubber extension that allows it to suck cold air from the fender will help that full temp torque thing.

[Wiscon_Mark]

yo, shazapple, it goes to the airbox ;)

[Plays_with_Toys]

Yeah, its running to the air box, which has a snorkusectomy, so it is pulling colder fender air.

[gil_ong81]

mine has the airfilter box removed, and in its place, i have a cone filter. after seeing those temps, I thinking of adding a length of piping to extend the filter into the fender. wonder if the MAF/MAP have to be right behind the airfilter??

[blackgtbeauty]

i had a cone filter, but it made my car run crappy. so i put in a GREEN panel filter and had the resonator in the fender removed, its sucking cold air from the fender, and i think my car makes more power this way, it runs better. not quite the growl the cone had, but it has a nice deep tone.

[Wiscon_Mark]

wonder if the MAF/MAP have to be right behind the airfilter??

I think it does :?

[Plays_with_Toys]

Have you looked at the MAF? Its a thin piece of wire. I wouldn't want unfiltered something or others bombarding it. Best to place it behind a filter.

Mark, when are you going to buy one and bonnify my results?

[Wiscon_Mark]

no, PWT, we meant, can it be farther down the line?

ie: The MAF is in the stock location, the filter is in the fender. The MAF isn't "unprotected."

The only problem I can see with that, is the MAF will probably read smoother airflow, and end up making the fuel/air ratio richer...

[EXP1787]

I'm going to have to pick one of these up. You said that in the eBay auction they specified the years, but did they make any reference to displacement? I understand that you are dealing with a 2.2, same as me, but I thought I'd ask.

[Plays_with_Toys]

They generally said the 2.5, however, as far as I can tell, all 1.8, 2.0, 2.2, and 2.5 engines have the same intake manifold layout with give or take, the same intake piping.

If you're not finding one for cheap, search for impreza intake. You'll get alot of turbo model intakes, but you should find some like the one above.

[Sarra]

If you can get some more tubing, you might be able to extend that short ram into the fender well. I've been thinking about doing something like that for a long time now, if I can find another air box for my car I may hack it up (I don't want a cone filter in my fender well, because, well, I don't quite have a complete fender liner in there right now, thanks to a boulder) and give it a go.

I also have a MAP sensor instead of a MAF, I think that will make a bit of a difference for me. I may even have to drill a hole in the intake for the MAP sensor if I decide to go with a short ram (and extend it).

[Plays_with_Toys]

My brother destroyed his focus when he sucked water into his CAI. I'll pass on putting the filter itself in the fender. Besides, with a snorkusectomy and hole plug, its pulling colder fender air.

[Sarra]

I went through a mud puddle so deep that the water part of it came up over the top of my hood. My entire engine was submerged, all the way up to the top of the airbox. I don't know how I didn't hydrolock my engine, but I'm glad I didn't!

can someone please post a pic of a STOCK BD engine bay/ intake tract?

thanks mark.

i'm surprised to see how diff yours look compared to mine.

i have the big box before the throttle body. and i'm missing (as in the DSPO probably threw it out) the "scoop" that goes to behind the headlight.

[Wiscon_Mark]

obviously mine's a lot different now...

who is the DSPO?

[gil_ong81]

He was a 17-yr old from PA. he did a few things right, but for the most part, it was a mess.

MRT headers and midpipe (good)

painted trim silver (no comment)
springs with stock shocks (bad)
installed front-R strut backwards after removing springs (VERY BAD)
mismatched, crappy tyres (bad)
painted tail light amber lens red (no idea what he was trying to do)
cone filter + MAF adaptor (good)
used speaker wire to extend O2 sensor wires (bad)

[BuruKid]

What do the vacumn lines and pcv line do?

[BuruKid]

What do the vacumn lines and pcv line do?

[Plays_with_Toys]

The vacuum lines pull out built up vapors in the valve covers and from the crank case when the engine is under load. Basically as the fuel combusts, some of it slips past the piston seals and ends up in the crank case. As the engine keeps going more and more is built up in the crank case. When the engine is under load, this exhaust is pulled up and recirculated into the combustion process. The reason it is only pulled up under load (when the PCV opens) is so that the engine doesn't idle rough/die when you're simply idling.

Is that a good enough explanation? It makes sense to me, but I don't know if the wording is coming across.

[Wiscon_Mark]

that was a very good explanation Dan :)

[strat81]

my ebay intake is sitting on my bed... i hope to be installing this tonight 8)

[strat81]

great write up! it works perfectly. 8)

[EXP1787]

great write up! it works perfectly. 8)
Yup! I used this thread today to assist in installing mine.

[supra90turbo]

To all of you who attest to the fact that the airbox flows more air than an open element, and the car runs better with it, I disagree.

proof? ok, i've got some.

My buddy has a 92 Legacy wagon. 5spd.
We race all the time, because it's funny, more or less.
so, his car was stock. so was mine.
we race, dead even.
he gets a cone filter from his old car and puts it on the legacy.
he pulls on me.
i've already got the snorkusectomy done, but yet he pulls on me.
i install the ebay intake pipe.
dead even now.
he gets an exhaust, and starts pulling on me again.
so, i get a cone filter
now I pull on him.

the difference?
17.3 1/4mi with air box and ebay intake pipe
17.1 1/4mi with open filter

i've since made a cold air box, and I feel that i should run a 16.999 at the very least...

http://img384.imageshack.us/img384/7349/dsc038250uj.th.jpg (http://img384.imageshack.us/my.php?image=dsc038250uj.jpg)

looks like that and functions incredibly.

[Wiscon_Mark]

Oh, no doubt an open air element is better, much less restriction, and a lot more filter area. Better for racing, maybe not as good for daily driving.

[supra90turbo]

Care to explain, Mark?
I don't find that statement to hold very true...

[Wiscon_Mark]

Because the of most cone filter designs, airflow is less smooth at lower RPMs and you lose a bit of torque. So unless you daily drive @ 4500 rpms all the time, you generally won't experience the advantage very much. Some cone filter elements don't compromise low end, it all depends. I'd go with Weapon R's design, personally.

[supra90turbo]

Actually, I do spend a good amount of time at high rpms.
seriously, though... Weapon R's design? Don't let the "computer generated" image fool you. There's nothing special about it.

[Wiscon_Mark]

outbackwbeer was a big advocator for it. I'm not concerned about their "flow technology", I know it's nothing so ideal in a real engine bay, but they are dual stage (the secret weapon is) and have the ram air option on that filter.

[redlegacygt]

supra90turbo:by any chance do you know the part number for that k&N filter?

[supra90turbo]

actually, it's not a K&N. It's something I got off eBay, the price was too good to pass up, and the filter itself isn't bad.

[Plays_with_Toys]

I finally realized why you're intake install looks so clean. You don't have ABS. What did you use to to block off everything? Looks like 1/16" aluminum with door trim sealer up top? So what did you make it out of? I wish I didn't have the ABS solenoid there, I pulled my fuse and now I just have to ignore the ABS light anytime I drive.

[supra90turbo]

Yes that's correct. One of the perks of driving a Brighton.
ABS FTL!

As far as the material, you're correct that it's aluminum. and I got it for less than half price because it was "damaged". Funny how a little complaining works sometimes...
IIRC it is 1/16", but I'll have to look at the tag again...

The strip at the top is simply automotive weatherstripping. I work at a GM dealer, and it just happened to be something that got replaced under warranty that GM didn't want back to verify if it was really bad, so they were going to throw it away. I took it about a year ago knowing that it would get put to good use :)
If you can't find any, let me know how much you need. I think I've got like 6' left, and I only used about 20" for mine. Plenty for at least a few more.

The bottom, mostly is vacuum line, held in by zip-ties.
I cheated where I didn't want to keep trimming to bring the high spots down, the higher spots just got weatherstrip, and it seals excellent.

I think today that I'm going to go down to radio shack and pick up a digital inside/outside thermometer to see the real heat blocking effectiveness.

[Huffer]

So, would this work also, hooking straight into the BD airbox?

[Wiscon_Mark]

No, it doesn't.

I was kinda pissed. It advertised direct fit. Second time I've been burned on ebay. However, I cut the pipe down and it does fit now. Not a total loss. I just had to buy another silicone sleeve.

and the brace thingy...I have no idea where that's supposed to mount on either end :roll:

[Huffer]

Show me a pic Mark - because I think I want to replicate what you've done.

[Plays_with_Toys]

Mark, what was wrong with the pipe. That looks identical to what I put on with 0 problems. There is no place for the brace that I know of as well.

[Wiscon_Mark]

It's the right shape, but way too long (in the direction of the airbox). Right now, I don't have it plugged in, as my idle air bypass is too choked with this pipe. I think I'll have to modify it with the drill and some hardware parts+welding.

It's funny, that bit about the idle air bypass...PWT said his worked fine (and his looks fairly small) but my stock one is rather large...probably the diameter (inside the tube) of a marble. It might be a weird '95 thing.

I really don't have regular computer access right now, so pics and stuff will have to wait, but I'll give you guys the full (understandable) scoop ASAP.

[Plays_with_Toys]

But, if you look at the size of the stock inlet to the IAB (the plastic piece), its actually quite small as well. Maybe the opening is too big, and an adapter to make it smaller would help.

BTW, I am changing mine up a little. I am going to put part of the snorkus back in. I'm going to see if there is a way to get a little torque. I basically just want to play around with it until I get the sound and power I want. I'm selling off my entire RC collection, so I should have around $1000 to tinker with (exhaust, cams, pulley, f/r sway, and shocks/springs).

[Wiscon_Mark]

I'll have to take a pic of my stock inlet...it's rather large (a marble could fit inside it).

Nice! Do you have a recommended ebay seller you bought from?

[JMoney]

I suggest you buy from delubozparts. They had good communication and fast shipping.

The product I bought was http://cgi.ebay.com/ebaymotors/Subaru-Impreza-Legacy-98-99-Air-Intake-System-Systems_W0QQitemZ300026765579QQihZ020QQcategoryZ38634QQssPageNameZWD1VQQrdZ1QQcmdZViewItem.

A couple of install notes:
1) The unit is not a direct fit in and does require "extensive" modifications in my unit.
2) Don't go to HomeDepot and get a 3in-3in coupler. They are way to big for the application. Go to Autozone and get the universal 3in-3in couplers that they sell. They are way more flexable and not so huge. They also sell different colors. In my case I got (1)3in-2.5in coupler, (1)3in-3in, and some assorted red silicone hose. The largest of which fit my application.
3) The pipe is not bent correctly so you will have to twist it a lot to get it to line up with the back of the MAF. As you can see from the pic, my coupler from the TB to the intake pipe is quite tweaked.
4) To solve the issue of the large vaccuum line going into the IAC valve, I just cut the platic piece that it connected to on the stock intake pipe off. I jammed the hose into it and then tee'd that into the other lines. I also hacked up the stock tube that connects to the back of the MAF so I could get the length I needed from the back of the MAF to the intake pipe. The difference is going to be roughly 4-5inches or more.

It looks easy, and maybe it was for other people, but it took me a good 45 minutes to get it togeather the way I wanted. It's not what I'd call a bolt-on mod.

[blackgtbeauty]

damn huffer your engines clean

[Plays_with_Toys]

Deluboz is who I purchased mine through as well. And no, it doesn't exactly line up. But there is almost always some shimmying around to get a custom part to fit. Still can't beat the price.

I just got the intake tube but no hoses and Im trying to figure out what else I need.

I already know I need:
1/2" T connector
1/2" elbow with male threaded end
MAF Adapter
hoses
teh more powar K&N filter

What size are the hoses that came with the intake?

[Plays_with_Toys]

Smaller than the T connectors by like an 1/8 or 1/4" Can't remember off the top of my head. I just know they are a very snug fit on the stock components.

[Wiscon_Mark]

1/2" T connector might not do it, considering you have a 3/4" Idle air bypass line.

[Plays_with_Toys]

Well, the thing about the elbow is it needs to thread into the IAB line. I remember reading about another person in an older impreza having stalling issues with too big of a plug for the IAB. Too much big of a surface area and it probably doesn't have enough pressure. I think even you were complaining of this mark, with the 3/4" bung on yours?

[Wiscon_Mark]

Actually quite the opposite.

The older Legacys and Imprezas have 3/4" Idle Air Bypass lines, the newer ones have much smaller (no idea what though) lines. The other eBay intake I had had a 1/4" line which was way too small and choked the engine.

[Superu264]

alright so I'll get 3/4 lines and slightly larger t connector/elbow?

[Wiscon_Mark]

Well, go and look first, but I believe the 3/4" line applys to you as well.

[Plays_with_Toys]

no no.

The only line that is 3/4" is the IAB. Everything else is like 3/8" lines (for your PCV system lines). Your T is going to be whatever size lines you get. Just buy some elbows and such, and keep your receipts. Then return what you don't use.

[Wiscon_Mark]

that's the only line I was talking about, Dan.

[Superu264]

I didnt know that was the only line you were talking about :roll:

[Wiscon_Mark]

Well, that's the only thing I commented on.

I never mentioned the EGR system, which would account for the other two lines.

Every eBay intake I've seen does fine with the 2 EGR lines, but most of them don't have a 3/4" line for the Idle Air Bypass line, they just have another small line like the EGR lines.

This apparently doesnt' apply to newer 2nd gens. I'm not sure though.

[Superu264]

does that mean its going to choke me out like it happened to you?

[Wiscon_Mark]

Mostly likely.

You can always see what you can get away with.

But I'd suggest resetting the ECU if you don't go with the 3/4"

[Superu264]

I dont know, I dont feel like going through the effort if it just chokes out. Maybe I'll try for one of those Bomb Effects :-?

Mark, did you connect a 3/4 idle bypass to the intake when it stalled out? Or did you use the smaller hose?

[Wiscon_Mark]

que?

[Plays_with_Toys]

rick, if you can post up a pic of your exact intake, or tell us how many bungs are on it. That'll alleviate alot of confusion. :lol:

[Superu264]

Its the same one you used:

[Reason]

https://sl-i.net/FORUM/images/imported/2006/11/141b6co-1.jpg

That's what I have, it's the wrong set up for the 97.

[Plays_with_Toys]

Ok, then just buy everything I have listed on the first page and you'll be fine. Autozone now carries the rubber couplers for intakes, so if you want it a little nicer looking you can buy one from there, but everything I have listed is what you'll need.

Mark purchased one that had a big bung for the IAB line, but these don't have that, so don't worry about it. You will need 3/8" lines to go into the two other bungs (I believe they are 3/8", you can check by slipping the line over the bungs on the pipe and see what fits snug on there.

[Superu264]

PWT, did the intake you got only have two bungs? Mine has 3 and is much longer ( :roll: ) so wouldn't that eliminate drilling the rubber coupler and inserting the elbow?

The intake:

https://sl-i.net/FORUM/images/imported/2006/11/IMG_1380-1.jpg

[Plays_with_Toys]

yeah, mine didn't have that third bung. It almost looks like you could chop off that bend and run it straight to your air box.

Do you intend to use the airbox or a cone filter at the end? If you're using a cone filter, then yes, that bottom bung might be too small and might end up choking off the IAB. I don't see why it would, because despite the fact that the line is 3/4" in diameter, on the stock piping the inlet tube that drops to this line is only 1/4"- 3/8". I'd get an adapter from 1/4" to 3/4" and see if it works, if it doesn't, drill out that bung and put a rubber grommet with another attachment (like the elbow I used) there.

If you are going to run to the air box, I would cut at the elbow and add the shorter auto zone rubber coupler between the intake and the MAF.

[Reason]

I bet you are itching to get that on lol.

[Superu264]

I'm going to use a cone filter

Going to head off to AutoZone or Advance Auto tomorrow to pick all this up so I'm trying to straighten everything out :grin:


I bet you are itching to get that on lol.

it's killing me, I'll be preforming a snorkusectomy as well :twisted:

[Reason]

I'll be preforming a snorkusectomy as well :twisted:

We'll you are using a cone filter, it wouldnt matter. But you don't want that crap in your fender if you're not using it.

[Superu264]

So a snorkusectomy wouldn't be worth it?


How the hell can I keep the intake stable? I have no mounting bars for it.

[Reason]

It's not hard, but if you are doing a cone filter it wouldnt matter, it's not being used.

As for a munt just make one.

[Wiscon_Mark]

Yeah, you're going to need a bigger bung (3/4") for that idle air bypass line.

https://sl-i.net/FORUM/images/imported/2006/11/IABline-1.jpg

That's the sucker (the one I highlighted).

[Six10Styles]

Just installed my ebay intake, all i needed was a T-connector i got at home depot for $1.80. I'm a bit weary about it tho, not really any clearance between the cone filter and the hood, the hood shuts fine, but its touching the cone. I'll figure sumthin out, but sum suggestions would be nice if u guys have any. Yes, i know, the engine bay is FILTHY :oops: . I'll get to it one of these days.

The seller is www.cosmoracing.com (http://www.cosmoracing.com), they're in canada and i got mine in maybe 2 days? they hav all kinds of colors (oooooooooo :roll: ) & included sum aluminum emblems to put on the intake, and outside of ur car (no thanks). I just reset the ecu, and still hav to put in my underdrive pulley & exhaust, but im done for tonite. let me kno wut u guys think...

https://sl-i.net/FORUM/images/imported/2006/12/dirtmode1-1.jpg

[Plays_with_Toys]

Take out the bottom half of your stock air box and rotate the intake down a little. Should have plenty of clearnace after that.

[Six10Styles]

Thanks, also, the IAB line is slightly kinked (hopefully it'll be good after i do what plays w/ toys said, but if not, does anyone know the diameter of the hose? maybe i can get a longer one & spiral it? i dont want to cut it and end up screwin myself(i dont think cutting it will solve the problem anyway). i havent noticed any difference other than it feels like a slight stutter at idle for a short time after i start the car up (might just be the cold).

[Wiscon_Mark]

This has already been covered ;)

Mine is kinked also slightly. It's a 3/4" line. I got some heater hose from advance auto to mess around with that.

[88rxn/a]

im confused??
i have a 95 legacy AWD 2.2
do i need:
1. http://www.cosmoracing.com/productinfo. ... 6&pid=1211 (http://www.cosmoracing.com/productinfo.asp?cid=226&pid=1211)

or


2. http://cgi.ebay.com/ebaymotors/ws/eBayI ... :IT&ih=020 (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=300026765579&ssPageName=STRK:MEWA:IT&ih=020)


or



3. http://cgi.ebay.com/ebaymotors/ws/eBayI ... :IT&ih=017 (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=270067736280&ssPageName=STRK:MEWA:IT&ih=017)

[Wiscon_Mark]

Option 1 would be the best for you since the 95 has the 3/4" idle air bypass line and you can see that the nipple on that one is the larger variety.

Option 2 doesn't have one of those, you'd have to fab it up like PWT did when he installed his eBay intake.

Option 3 is the first variety of eBay intake that I bought, and it's too long and has a smaller nipple for the idle air bypass line that was used on the newer Legacys and Imprezas (97+)

[Six10Styles]

ya, go with option one, i have a 95 as well, all u need is a t connector from home depot, sum heater hose(i got mine at pepboys), and take out the bottom half of the airbox & it fits perfectly. very easy to install, and they ship it out REAL FAST. they have the intake in red, blue or polished. sounds nice too

[Plays_with_Toys]

Option 1 is only really worth it if the filter is good. I bought mine through deluboz (option two) and got it within 3-4 days. I have a K&N in my stock box, so I was fine without a filter.

[Reason]

I have option 2, But I need the first one. I dont have everything hooked up, lol so far no probelms :grin:

[2.5GT]

cosmoracing is full of crap.
I sent them an email over 2 weeks ago, and still no awswer.

I want to buy an intake off their website, but the only payment option i can make is money order. So i send them an email asking how much would shipping be and all.

[dodik]

I actually installed similar intake from ebay 45k miles ago and it does improve the way the car breathe. Smoother shifting out of my 4EAT more torque better gas milage and i dont care how cheap it looks it works very well. and another thing i read in some car mag it is better if you install intake and exhaust systems together because you can better feel the difference.

Yea, its true.. the intake + exhaust system together will make a difference. Right now i just have an intake installed.. seems to run a bit rich though.. wouldnt that decrease the gas mileage? I reset the ecu a few times.. and it seems about the same.. not smoking or anything, just the exhaust smells of fuel a bit.

[blackgtbeauty]

Since you letting more air it would run a little lean if anything.

Unless your ECU is over compensating for it and adding too much fuel :-?

[Wiscon_Mark]

Yeah, that's usually what happens when it sees something it doesn't like - it'll run rich to be on the safe side.

[Superu264]

it'll run rich to be on the safe side.

mine has always run rich :-?

[d1giPhux]

There anything i can really do about it? I dont want it to be running rich much. but i dont think there is much i can do about it huh? Hmm, that kinda sucks.. almost makes me want to put the stock airbox back in. :cry:

An Air/Fuel Ratio controller. There's other threads about that, I'm not too familiar with it.

[d1giPhux]

Yea.. figured.. thats about the only thing i can do. Not worth spending $300 to fix that though.. i mean, it would be cool if i was rich, but im not gonna buy something 6 times the cost of an intake to fix the damn a/f ratio =/ .. i like the intake.. i just dunno bout running rich all the time. Can it cause damage in the long run really?

Actually an A/F controller if tuned right can really make the most of your mods. If you have a lightened flywheel/pulley, intake, and exhaust, get an A/F controller and then cams, and the car will be real peppy (I've read anyway. But many people say that engine management does wonders.

[blackgtbeauty]

i mean, it would be cool if i was rich...

But you are "rich".

Ha. Ha. Ha.

[d1giPhux]

:lol: oh man, LOL.

Yea, i heard a/f controllers are really worth it.. but i dont have the $$ to drop just to deal with the intake issue. Maybe once i buy a full exhaust setup / header / pulley.. etc.. then it might be worth it. But until then, i guess i'll just be running rich!

[Wiscon_Mark]

enh, stock is a rich map too. I wouldn't worry about it.

[d1giPhux]

enh, stock is a rich map too. I wouldn't worry about it.

Before my exhaust smelled more like oil.. now it smells more like gas. No big deal either way.. i just hope im not eating up a whole lot more gas now. =/

Do you know the part number to that T connector?

[d1giPhux]

What do you need the t connector for? On my intake i used a 3/4" hose barb that fitted to a 1/2" hose barb and then did the big line, and for the other small lines i juse used the stock t connector in the car, and the one going to the intake? Also.. if your connector is too big and your hose is too small, what you can do is get a cup of boiling water.. and i mean boiling.. and stick the hose in it for about 30-45 seconds.. then put it over the barb you are using and let it cool. :wink: ghetto fab!

Also.. i made a cool bracket to hold the intake down by using a computer PCI slot cover.. you know, the little metal pieces that cover the ports on that back of your computer.. if you dont have one, bust the case off your computer off and unscrew one, and there ya go.. perfectly good piece of bendable metal ready to have holes drilled and used as a bracket!

[2.5GT]

Shoot, I bought a used '05 RS Injen Intake.

Decide to run a short ram instead of CAI. And the tube only has 2 bungs for vaccum lines. I used the stock connector of my OEM air box and that works great. But the IAB (sp?) hose doesn't have anywhere to go. The car starts and dies because of that hose.

So I need to run another T connecter big enough to fit that hose, I think It's 3/4? Do they make T connecters that big?

Yea i have a short ram too, i went to home depot and got 2 parts :

3/4" connector barb
1/2" connector barb

One screwed into the other, and in the store i went to, they only had one of each that fit perfectly to make this match.. i will go take a picture for you.. im proud of my ghetto work! :cool:

I was trying all day to make this work. My ghetto fabulous vaccum lines are crazy lol. And most importanly, I need hoses that actually fit the bung.

This project goes off to another day. It's way too cold outside :roll:

[d1giPhux]

Yea, that big hose was crazy.. luckily i just bought the parts before hand and made them fit. I suggest you get a better hose for the 1/2" side as well. Go to advanced auto or some shit.. cut a little piece off the end of your current 1/2" hose and bring it to them. Ask them for the plain black hose they have for sale.. i bought a 2 foot piece it was like $3 or less. Then connect the 1/2" hose to the 1/2" side of the barb.. you may need to heat it up a little in boiling water.. you may not. Then just screw the 1/2" barb into the 3/4" barb.. like i have in this pic :

https://sl-i.net/FORUM/images/imported/2007/02/hoseconnector-1.jpg

I reccomend the better hose though, because the stuff they sent you with your intake is probably that cheap plastic colored hose.. and if that bends while you are driving around.. your car is going to bog out and die. I know.. because it happened to me. From the wind and stuff of going fast, the hose got a little pinched and basically it shut my car down. I forget what they call that hose. but just ask them for 'plain black hose' and preferably that will fit over 1/2" barb if you cannot cut a tiny piece off your current hose to show them. I just clipped the smallest piece off to show them the diameter.. hope this helps.

edit : shown in the pic is the 1/2" hose connected to the 1/2" barb, which then screws into the 3/4" barb.. which then goes on the idle air bypass hose (big ass hose).

[2.5GT]

Yeah, the cheap ass hose was so bendy, that it bends where it connects to the bung, that cause it to stalled.

But you have a whole engine pic where I can see your intake set up? :grin:

[2.5GT]

And did your pipe came with 2 or 3 bungs?

I makes it hard for me cuz It only came with 2 on mine. So I have to route all my vaccum lines to one T connector. Ima have to do it all over again.

Mine only has 2.. i routed them the same way the stock ones go. You know how on the stock thing its got that t connector that connect 2 hoses, then goes to one.. thats what i used. Let me see if i can go get you a pic.. its hella dark out, but i'll try.

[2.5GT]

Yes, the big T connector that goes on the back of the OEM air box. Thats what I used. That solves the vaccum problem for those 2 vaccum lines.

But the IAB (sp?) still has no where to go.

[d1giPhux]

Alright.. check it out.


Here is an overview.. u prolly cant see much :

https://sl-i.net/FORUM/images/imported/2007/02/intake1-1.jpg


Here are how the hoses connect :

The red arrows show the connection from the intake, to the engine where it needs to be connected. Just connect from one red arrow.. to the other.

The blue arrows show the intake connection, which goes to the 1/2 - 3/4" connector you will be making, and then the 3/4" connector which connects to the Idle Air Bypass. Basically your intake connects to the adapter, which connects to the big ass 3/4" idle air bypass hose.. like in the picture.

https://sl-i.net/FORUM/images/imported/2007/02/hosesconnected-1.jpg

All you need to do is match up the red arrows and the blue arrows.. let me know if that makes more sense?


Here is the t-connector.. which goes to the 2 hoses that run the valve covers on the right and left side of the engine.. i also put a breather on the top of my stock t connector.

https://sl-i.net/FORUM/images/imported/2007/02/tconnector-1.jpg

[2.5GT]

I basically did the same thing, well almost.

But that T connector, It's not connecting to any vaccum line. You just put a breather on it?

[d1giPhux]

I basically did the same thing, well almost.

But that T connector, It's not connecting to any vaccum line. You just put a breather on it?

This is an illustration of the t connector. It basically is the stock connector from the car.. one side connects to the right valve cover, the other side connects to the left valve cover, and the top part connects to the breather.. or you can just leave it open.

https://sl-i.net/FORUM/images/imported/2007/02/tconnect-1.jpg

Also.. when i say t connector.. i mean the stock t connector like show in the last picture with the breather on it. The 1/2" - 3/4" connector i made connects like in the picture with the blue arrows. It goes from the Idle air valve, to the place on the engine.. except you need the 1/2" - 3/4" adapter so that you can adapt the 1/2" hose from your intake to the 3/4" big ass idle air hose on the car. Hope that clears things up a bit.

Nope.. it wont hurt the engine at all..I asked the same questions before doing mine.. it will do nothing.. its still getting air, just not from the intake.. which doesnt matter anyways. I put a breather on it just to make sure it didnt suck anything in by accident.. but, i dont even know if it sucks anything or not.. im pretty sure its just so the line can breathe.

been running like that since i put it in.. about umm.. a month or more? Everything runs great. Just make sure you get some better hose for the connections that hook up to the intake, or else you will choke it out.. and it doesnt like that!

Thanks for the pics man, It helps out alot :eek:[/quote:t98ypco9]

been running like that since i put it in.. about umm.. a month or more? Everything runs great. Just make sure you get some better hose for the connections that hook up to the intake, or else you will choke it out.. and it doesnt like that![/quote:t98ypco9]

No, i found that out the hard way :lol:

at first i though it was my battery, since it was so cold :roll:

[Wiscon_Mark]

I would connect all the EGR stuff - not only to avoid CELs (although unlikely) but to keep carbon monoxide out of the HVAC intake - Dan had a problem with this - he was getting tired at the wheel WAY more than was normal, plugged his PCV line back in, and noticed a definite difference.

Aww my old intake, I miss it :-( lol I painted that with ceramic header paint and smoothed the inside a bit :smile:

Oh yea, seems like you guys are making this install hader than it really is. I think it took me longer taking the old intake out.

Haha, i did the same thing.. made the install harder then necessary.. but eh, once i took the old box out and asked you a few questions.. everything was good! I just posted up pics to help him out / help other people out in the future!

[2.5GT]

I'll get my Injen set up in awhile, just have to run out to Homedepot to get some hoses :lol:

[2.5GT]

Alright, as promise, I installed my Injen intake today. Cold as hell but I got the work done :eek:

It's an Intake for a '02 RS, I just hack off the part I needed.

Performance wise, Im not quite sure. Still feels the same, and not as loud sucking noise :eek:

[Plays_with_Toys]

it should be able to breathe better up top. Definately a very nice unit there.

[2.5GT]

Yeah, the throttle response was pretty quick. Sounds pretty nice too :eek:

[d1giPhux]

Yeah, the throttle response was pretty quick. Sounds pretty nice too :eek:

Hells yea man! Wasnt the install easier than you thought? Glad you got it working all right!

Now all you need to make is a custom bracket to hold the MAF / Filter to the body of the car! I made one using a computer PCI slot cover and just drilled 2 holes in it.. came out perfect!

It surprise me because it actually didn't rattle when I step on it. But still be cool to have a bracket in place.

Yea, mine doesnt rattle without a bracket either.. but i made it so that it would keep it down, so eventually it wont wear the paint off my hood from bouncing up and down over bumps / dirt roads etc.. its super easy too.. took me like 20 mins.

[importtund]

So I ordered my intake last night and it came with 3 vacum lines, so ummm? it said it was for the 98-99 RS IMPREZA, so ummm yea does this mean I wont have to do all that custom shite n' the write up?

[d1giPhux]

it just means you will have an extra tube (like stock) that you will either need to plug, or connect to the valve covers (left and right side) with a t connector, then connect them to the intake.. if you want.

Basically it just allows you to have one more dedicated line for cold air =]

The way i have mine set up :

1 line goes to Idle Air bypass line (3/4" Big ass one)
1 line goes to PCV Valve Line
1 (your extra line) Can go to valve covers (left and right w/t connector) .. i had to hook mine up to a breather, but it might be cool to have it hooked up to the intake anyways. Someone correct me if im wrong.. but im pretty sure this would be a good option, rather than just plugging the extra line.

So to make things short.. yea, just hook it up like the stock intake on the car! LOL :lol:

[Wiscon_Mark]

what are you talking about?? Why wouldn't you send both of the vacuum lines to the EGR system? Neither go to the PCV valve, that's different.

[d1giPhux]

Sorry, i didnt mean it goes to the PCV valve line.. i only know thats what it says in the beggining of this thread.. i dont know what the name of that line is.. i only know the name of the IAB valve line, and the other 2 which go to the valve covers... the one im speaking of is the 1/2" line. *gives mark a valium*

Here is a picture of the line im taking about.. it has the red arrow on it :

https://sl-i.net/FORUM/images/imported/2007/02/hosesconnected-1.jpg

Oh.. and what is the EGR system? Using terms like that will probably just confuse people even more (like me). LOL just hook it up like stock and you should be good to go!

[Wiscon_Mark]

EGR means "exhaust gas recirculation" and it's what those two other lines are for...hook them up to the stock locations, don't put a breather on them.

Dan can vouch for that being a bad idea.

Why is that a bad idea? Ive been running it on my car for a few months like that now.. and i dont have any trouble. Its still just breathing air.. just like it would be out of the intake.. what is the difference? :-?

[Wiscon_Mark]

because you don't want exhaust getting loose in your engine, and it's beneficial to be drawing it back into the intake, no matter what people might tell you about oxygen content in the intake.

[Reason]

because you don't want exhaust getting loose in your engine, and it's beneficial to be drawing it back into the intake, no matter what people might tell you about oxygen content in the intake.

Why so? Wouldn't too much exhaust or none at all alter air/ fuel ratios leaning it out or making it too rich? Even if it's a slight alteration a simple air/fuel tune should set everything straight.

[Wiscon_Mark]

Look, I'm not a wizard on the EGR system, but many techs agree that it's there for a reason. Honestly, you can't tune with that in mind, really, because it all comes in after the MAF.

[Reason]

I think that's more to do with environmental purposes. I bet without that crap going back into the combustion chamber you would have better gas mileage.

[Legacygt_97]

because you don't want exhaust getting loose in your engine, and it's beneficial to be drawing it back into the intake, no matter what people might tell you about oxygen content in the intake.

Here we go with you again. Do you have the slightest inclination as to what function the EGR system serves? If combustion temps are too high, NoX (oxides of nitrogen) is produced. It is a harmful gas. By introducing slight amounts of exhaust gas back through the intake, the combustion temp is effectively reduced. Your bad advice is going to cause someone to blow up their car. I thought you were going to stay out of the engines forum anyway?

[Wiscon_Mark]

My bad advice is going to make someone blow up their car?

ARE YOU RETARTED?

I told them to leave it in, dumbass, like stock!

I figured it was like the PCV system - to get exhaust gases that make it past the seals and such out.

So, are you just hunting around to make fun of me, or what?

Yeah, I did stay out of the engine forum, this is the DIY...have you lost your way?

If you all you're going to do is be an ass, leave.

[d1giPhux]

Holy shit.. I come back and see ive started a goddamn war of NASIOC proportions. :lol: People need to chill out a bit here, we're all learning.

I'm still confused as to why its bad running the lines on a breather? I haven't really had any problems with it so far.. but .. maybe im just misinformed or something? I think i will just keep it this way.. because so far for the months ive had it.. its been working.

[Wiscon_Mark]

While I sincerely doubt you're going to blow your engine by not hooking the EGR lines up, I would suggest you do, just as stock.

Maybe you should take a picture of where you're putting this breather?? I mean, if you put a breather on, post-MAF, it's likely that you're going to run the car lean (well, consider how stock is so pig-rich, it may not actually go lean, but it's not a good idea to chance it) and that may cause problems.

[importtund]

:shock: look guys thanks for the help, sorry I asked... I'll figure it out I'm sure! :lol: ( it's really not that serious)! :lol:

[d1giPhux]

The breather is just connected to the 2 valve covers on the left and right hand side of the engine.. the lines that come from those 2 covers, that usually connect to the stock t.. i just have the stock t connector hooked up to a breather, rather than leaving it open..

https://sl-i.net/FORUM/images/imported/2007/02/tconnector-1.jpg

I'd suggest you hook it back up.

Here's a link I found about the EGR system:

H'mm.. well i might. Its working fine for me right now, and if you look at the way the stock box hooks up.. i dont even think it gets any of the intakes air.. i think it just breathes off of the same box.. but im not sure. It is working fine though, but maybe if i have some spare time i will connect it the stock way.

[Wiscon_Mark]

It's not supposed to "get" air, it's supposed to give air. I don't know how you can say "it's working fine" since you're not going to be able to tell by just driving the car around...

[ooberdoob]

y'all bicker so much lol

it's like you're step-brothers or something. :lol:

anyhow...

i'm looking to do something different to my intake... don't know what to do though :?:

[Legacygt_97]

Those two lines are the fresh air breathers for the PCV system. The PCV valve is a calibrated vacuum leak. The air that is drawn through the PCV system to vent blow-by gasses must be included in the total MAF count. Otherwise, the car will run lean. The oxygen sensor should counteract this, but to a kinda limited degre. Your long term fuel trim may be affected and the correlation between the expectd readings may trip the MIL. I would hook up those lines as close to stock configuration as possible.

Sidenote:

Mark, I've sen some horror show quality material when it comes to simple mods gone wrong. I've seen heads cracked frompople running without a thrmostat. It can cause th coolant to not circulate to certain areas of the engin causing severe hotspots. EGR can cause serious problems if dosconnected too. I worked on an old Benz 380SL that had cracked the tops of all the pistons because the engine ran lean due to the EGR ports not being properly plugged. Granted that was a Benz not a Subie, same idea tho. The same thing COULD (read not very likely) happen with the breather system on a Subaru. The potential ill effects however justify the extra effort to mod it properly. I'll refrain from the harsh remarks unless absolutely warranted.

Thats weird you run lean from it.. i get NO CEL light, and my car still seems to run rich.. strange. I dont know.. i think im going to just leave it the way it is.. im having no problems, and it is working fine for me. Sure.. i may not have data sheets to prove nothing is wrong with it.. but i can usually tell from strange symptoms if something bad is happening.. I.E sputtering, RPM's, just how the car feels in general. I would hook it up.. but i just really dont see how its going to help anyways? I think Reason has the intake set up the same way on his car.. and i dont think he ever had any trouble? Maybe someday when i get the chance i will try it out.. but instead of drilling a new hole in the rubber elbow or something, woulndt it be easier to just use a t connector to piggyback it off one of the other main hoses on the intake? I dont know.. just seems like a bunch of work for something that makes very little difference.. or in my mind at least. :roll:

[2.5GT]

I'll try something out and get back at ya. I still want to keep my Intake, looks better anyways :lol:

[2.5GT]

Today I went out to Homedepot and re-did the vaccum lines.

Remember where the breather used to sit? Here's the "T" connector I made to hook it up.

Photobucket is not loading for me, so i cant upload the edited pics.

Look closely at the 1st and 4th pic.

There's a hose coming from the PCV, to the "T" connector. The "T" connector has 2 more hoses hooked up to it. One hose goes to the stock "T" (where you stuck the breather at) And the other straight to the Intake pipe.


Didn't notice difference, still the same start up and accelerating.
The Check Engine Light went away, then came back, then goes away, then comes back again! :eek: ...Check it with a scan tool, it reads Knock Sensor Bank #1. Oh shit :shock:

[Wiscon_Mark]

Did you do a reset after you made these changes?

[2.5GT]

I had the engine out, and battery disconnected for 1 day.

After the work as been done, Engine installed, Intake Installed. The Check Engine Light pop up. It comes on and off, I have no clue.

[ryankenn]

I'm going to add my $70 "ganzflow" knockoff to this thread. The bulk of the cost is the $50 K&N filter, but according to what I've read, keeping the stock torque box and just having a tube /cone filter combo attached yields the best balanced results.

I have to say, keeping that box makes the intake LOUD under WOT though. It seems to resonate in there.

[TRUBLU]

well, I made this up one for the fact that it truly is a 3" opening comapred to the 2.5" of the ebay intake. I wish I could take a soundclip of this intake. I don't have any exhaust modifications abd the cars intake can be heard at least a 1/4mile away when I really put the pedal down and get it into mid RPMs

https://sl-i.net/FORUM/images/imported/2007/04/3-1.jpg

[Wiscon_Mark]

My eBay intake is a 3" diameter.

[TRUBLU]

interesting! The ones I looked at only had 2.5" so I thought...well screw that for a joke I'm going to make my own! All up it cost me less then $50 including the pod!

[TRUBLU]

oh and for those keen of the eye, no I didn't use a connector pllate to mount the MAF to the filter.

[redlegacygt]

by chance does anyone know the part # for their k&n filter for the intake? i had it and lost it :roll:

[caoutback]

With help from Mark and this DIY post I got my e bay intake installed. It was for an RS and only required it to be shortened to fit with my factory air box. It really work up the engine and make the acceleration better and the butt dyno enjoys the gains. Much appreciated to this post and Mark.

Awesome! Just an addendum, check your bungs for cracks in the welds. The one that faces the firewall on mine cracked. I plan to patch it with some JB weld.

[StatGSR]

figured i might as well toss my intake engineering on here...

here is the stock nipple for the plastic intake arm. i notched a peice of copper pipe to sleeve the nipple so i would have more surface area to apply jb weld.

befor welding make sure u test fit and get the direction of the nipple correct.

https://sl-i.net/FORUM/images/imported/2007/12/DSC01883-1.jpg

this is how it looks inside the car. i had an extra elbow around so i decided to use that. here u can see how the extra coupler is needed if your intake only comes with he one for the throttle body. and on the filter side of the sensor u can you see the maf adaptor plate. i needed to drill some new holes into to align it well. also u can see my custom bracket i made to help support. it may look like a lot of extra work, but it really wasnt that time consuming.

um just an observation, to the person that had there intake made out of PVC piping, PVC at high temps releases a toxic fume, that if it gets into your engine, your screwed!, Just an FYI, if your gonna custom fab one like that you should get ABS plastic or go and have a muffler shop mandril bend you a custom pipe!,

I installed my e-bay intake, and I needed an "L" adapter for the Idle air Bypass to connect to the intake... I used a PVC Heater line connector...

Dehydrochlorination of PVC Materials at High Temperature

Xue-Gang Zheng,* Li-Hua Tang, Na Zhang, Qing-Hua Gao, Cheng-Fang Zhang, and Zi-Bin Zhu

Research Institute of Chemical Technology, P.O. Box 274, East China University of Science and Technology, 130 Meilong Road, Shanghai 200237, China

Received June 5, 2002

Abstract:

A relatively large laboratory-scale sample of a commercial type of PVC material usually used in building, flooring, home furnishings, clothing, etc., is thermally decomposed under carefully controlled conditions. Dehydrochlorination of PVC material at high temperature (up to 600 C) has been studied. The results show that dehydrochlorination beginning at the temperature of 150 C can be divided into three stages: low-temperature moderation in the temperature interval 150-180 C, medium-temperature acceleration in the interval 180-250 C, and high-temperature moderation in the interval 250-280 C. The release of chlorine as HCl from PVC materials, at the same temperature, is highest in oxygen, and it increases with an increase of oxygen content. The release of chlorine as HCl is higher by about 5-10% in hydrogen than in nitrogen. In addition, the effect of additives such as dioctyl phthalate (DOP) and calcium stearate (CaSt2) on dehydrochlorination of PVC is studied. The release of chlorine as HCl is markedly reduced by additives.

[Brockley]

the one I got looks exactly like what you have on the right (black one) but L shaped... I swear its ABS, but the box said PVC...

But does anyone think that even if it is PVC, that it would reach any high temps where it is located (basicly in the curve , 8 or so inches from the Throttle Body)

[2.5GT]

It'll be fine :wink:

[02legacygt]

yeah, i was just throwing that out there not to worry anyone , only to educate and like huffer wrote it has to get REALLY hot to break down, so unless you have a giant turbo underneith it producing super heat , or you have it running right along your exhaust mani. you should be fine. I just heard of someone making a custom intake for there first gen neon and that is what happened to them..... im just trying to pass along the knowledge

I'm sure I've mentioned it before, but there is a 100% OEM option for this mod, the 96 GT intake tube.

im getting ready to install mine on my 2.5 and i was wondering about how much hose i will need? im not going to use the blue ones that came with my intake so im going to go buy some black hose and was wondering just about how much i would use. Also, ive read in this thread about a t connnector, where exactly is this used?

The intake i bought off ebay looks like this:

https://sl-i.net/FORUM/images/imported/2008/03/IntakePipe-1.jpg


I noticed on my stock piping (the big afterbirth plastic box before the throttle body) there are two hoses going into it at the bottom, one larger hose going into the stock pipe, and antoher smaller one going into the stock pipe.

As you can see, the pipe i got off ebay has three bungs, one larger one and two smaller ones. Will i use the t-connector for the two at the bottom of the factory piece before the throttle body?

[Brockley]

Get a "Y" adapter instead... Those lines are from your Valve Covers, and if you do put a oil catch can inline, it will need to be a Y instead of a T, or the oil will just go to the other Valve Cover.

Those should be connected, and attached to the TOP fitting in the pic.

then, hook up the other hoses...

but, I def would do a Y instead of a T if installing a catch can...

[2.5GT]

Or reuse the stock one that came off the back of the intake box :wink:

[jjs316]

I just reused the stock piece that clipped to the bottom of the factory intake and just ran one line off it into the top bung on that intake pipe.

hey guys i just wanted to say thanks! this thread helped me figure out what was going on w/my intake system. Good pics and great comments/info. just thought i'd let y'all know this is definetely doing some good!

the problem, by the way, was that the previous owner had installed breathers on the valve covers where the vacuum line was supposed to hook up and connect to the T and the to the intake.

So i only had lines running to the intake for PCV and IAC, which was not the 3/4 it should be. Basically i just looked over this thread a couple times and figured out that i needed to make my valve cover lines and set them up to the top knub on the intake, going through the T splitter first of course. Then i drilled a hole in my 3" coupler and attached a 3/4" line to it for the IAC and i was done.

the car certainly acts happier now with the ECU reset and all lines correctly in place. i noticed the difference mostly at start up, where it would idle strangely before it's consistent now. so to make an awkwardly long post short...


Thanks to SL-i for helping me resolve yet another problem.

[2.5GT]

yar..glad you fix the problem :eek:

[Huffer]

I'm sure I've mentioned it before, but there is a 100% OEM option for this mod, the 96 GT intake tube.

Don't even bother trying to get one from the dealer, they're $100+, but they can be found used (https://sl-i.net/FORUM/viewtopic.php?p=88296) :wink:

I just installed this intake last night on my 98 GT. I didn't notice any power gains but the car did feel a bit peppier. Noise wasn't greatly increased either. I hooked up all the hoses using the two longer ones that AussieDan sent me, and cut one of my stock ones a little shorter to mate up better.

Benefits? Less visual clutter in the engine bay, no potential for rub on the front strut bar, OEM looks, easier to reach back behind the engine, good excuse to clean up the throttlebody a bit.

Took all of 20mins to install.

Thanks again Dan!

[AussieDan]

Glad to hear you're happy with it! You need to take some shots of the engine bay with it installed, I never got around to it.

[Huffer]

Pics will come... but it's going to look just like a 96 GT w/ a white bay. :lol:

I can confirm that the intake smoothed out the bogging I was getting in 3rd at WOT - in fact it's not there anymore. This is without an ECU reset too.

Basically, if I was doing 30mph in 3rd, and went WOT, the car would rev quickly to 4500rpm and then drop all of a sudden to 4000 and slowly creep back up before I could change to 4th... if I modulated the gas pedal a bit I could minimise it. But now, no problems at all.

She's back baby, yeah!

Im wondering, would this work for the intake:

http://cgi.ebay.com/ebaymotors/Parts-Ac ... .m14.l1318 (http://cgi.ebay.com/ebaymotors/Parts-Accessories_Car-Truck-Parts-Accessories__95-01-Subaru-Impreza-Short-Ram-Air-Intake-99-98-97-96-9_W0QQitemZ180266915215QQddnZPartsQ20Q26Q20AccessoriesQQadnZCarQ20Q26Q20TruckQ20PartsQ20Q26Q20AccessoriesQQddiZ2811QQadiZ2865QQcmdZViewItem?hash=item180266915215&_trksid=p3756.m14.l1318)

Also im thinking of doing a hybrid setup: Basically keeping the stock air box (with K&N filter) and taking out the snorkus and putting in the metal tube. Would that work or should I go with the full swap? Thanks

[99gtlimited]

it looks like it would work, but you may have some problems with couplers, i just bought a 3" one for the end that hooks up with the MAF/airbox and a 2.75" coupler to connect the throttle body and intake tube. I used a weapon R intake tube, so you may have to do a little trimming if the piping gives you an y trouble. here's what i came up with. (fairly recent pic)

https://sl-i.net/FORUM/images/imported/2008/07/IMG_3729-1.jpg

personally, i love the sound and the unique look

[Bhatman]

Thanks for the picture, wheres the Idle Air Bypass tube at(im guessing its underneath)? Did you use adapters like some other owners did or did you put the IAB straight on the bung?

[99gtlimited]

yeah it is underneath and hooks up with a hole in the 3" coupler directly after the MAF

[99SUS SFD]

Yeah I found out today that the Cosmo intake is just far enough away so that you can't hook up the idle air bypass. Time to go to the store tomorrow and get an elbow joint to make it work.

Looking forward to driving the 'ol girl though.

Here is my setup:

https://sl-i.net/FORUM/images/imported/2008/09/IMAGE_008-1.jpg

I'm thinking of installing a cone filter but i can't find an MAF adapter one online for any less than 20 bucks... That seems like a lot for a little piece of metal..

[liquidracing]

[anothernord]

Oops, haven't checked this thread in a while :neutral: Anyway, I started out with the hybrid design, It worked well, but I enjoy the sound of the cone filter too much, and since I drive a manual,

Edit: With this setup I do get the characteristic bogging between 1000-1800 rpm at WOT, but I have learned to not floor it down there anyway.

Just Bought the Intake...the picture on ebay had three vacuum lines and connections....The intake I got only had two...now I have to make the connection myself...I guess that is what $6.97 gets you.

Yeah, you can either weld or braze a bung on there or just drill a hole in the big rubber coupling and stick a plastic elbow in there. I also would recommend a better filter, the kit filter is not the greatest quality.

[BlackBK]

I think im going to do it right and weld it in there. I also disputed it with paypal so i am getting my money back.

[BlackBK]

I changed my mind and picked up a 96 intake tube off a 2.2 and bought a MAF adapter with cone filter....
The ebay intake i got was total garbage, wish I never bought it.

This is BMC CDA air intake. The best You can find in Europe:

And final instalation:

[winston856]

List of things you will need:
1/2" T connector
1/2" elbow with male threaded end
3" to 3" flexible coupling (rubber) (the metal clamps are included)
1' of 3/4" hose (*** I did not need this, but the insurance of having this hose is worth the extra $1.30)
Total cost of extra materials should be around $12.

That 1/2" elbow, doesn't that have to be 3/4" at the part where it connects to the Idle Air bypass hose? It's a pretty big hose but I'm not sure if it's 1/2" or 3/4".

Also if the IACV hose is 3/4", why wouldn't you drill one that big in the 3" to 3" coupler? Why just a 1/2"?

EDIT--- Nope, I was wrong. It's all 1/2".

Probably a stupid question, but where can I get those T valves and elbow with the threaded end?

Anyone know where I can get a CARB Legal Sticker for this mod?

It would be nice not having to reinstall the stock intake whenever I have to get my car smogged.

This would be frickin awesome if you dont intend on driving anywhere that has snow/puddles/anywhere with precipitation. thats why im not a big fan of in-fender intake setups. but to each their own. if it does the job well enough and ur a city/highway driver
then it seems in-fender is the way to go. sucks that im never going to be in that group = )

Did anyone else notice a decrease in low end torque under 2000rpm and a momentary hesitation at about 2,800rpm at light throttle? Where the car is accelerating slowly at about 1/4 throttle and when it hits like 2,800rpm you can feel the car struggle, its not bad, but noticable. Its only in first and second.

Anyone?

I believe the hesitation was from the ecu re-learning everything, because its gone now. Lol :)

I cant find these ebay intakes over ebay anymore :(

then get creative and make one!!!! :twisted:
