So I've finally completed my intake system, after many different set-ups, i've come up with one i'm finally happy with and happy to share with all of you.
Time From Concept To Installed Product: ~ 3 hours
So here's the basic idea: (preface)
I used the stock airbox (1) with a K&N drop-in filter in conjunction with piping from a Weapon R SRI (2) (although the ebay intakes would work just fine). I used a 2.75" coupler (3) to link the TB and intake piping, and a 3" coupler (4) to link the piping with the MAF. You have to drill a hole in the larger coupler to insert a 90 degree elbow with a 3/4" line that runs to the IAC. The other two bungs on the intake should go to the PCV and the Valve covers (i used a T joint (5) to link the valve cover lines and run them to the intake piping)
This is what it looked like with the the Hybrid intake set-up and a snorkus removed with the factory fender plug installed.
WARNING: DO THIS AT YOUR OWN RISK!!
0.If you haven't already removed the snorkus, you need to do it before you can make this intake. (you need to remove the fender liner to get to it properly and remove it)
With that out of the way you should see this: a lot of room behind the foglight
1. With the car safely off the ground and the front right wheel off (passenger side) you can see the inside of your airbox through the hole where the snorkus attached to the airbox.
With your cutting tool of choice, cut the top part of the snorkus off at the elbow where it connects to the airbox (we're gonna use this connection)
2. Now that you've cut the end off, you need to file the edges so there are no major burrs or sharp points. We're gonna connect this tube to a piece of 3" diameter PVC piping that will be aimed down behind the foglight to draw air much colder than that drawn in from the engine bay. I used about 10" of the PVC. I bought a 2' piece of 3" OD PVC for ~$3 and a 3" bracket to hold it for ~$2, so all in all the cold air part of this mod only cost me $5!

I put some mesh over the end of the tube to prevent it from sucking up anything that may make it's way back there.
3. Next part is modding the bracket to support the tubing. I used a 3" round bracket to hold the tube (#2) and connected it to a hard steel piece i broke off the end of the round bracket for lateral support (#1) and hung it with plumbers tape for vertical support and shock absorbtion.

4. Once you've got it all cut to size you have to fit the plumbers tape on the round bracket to help support the tube in the fender well.
I used a small nut and bolt to fix the plumbers tape to a hole between the airbox and the fender plug hole.
5. Now you can install your fender plug and get back underneath the car. I attached the more rigid bracket to a part of the frame near the bumper using a nut on the bolt of the round bracket and a nut and bolt into the frame. (#1)
6.Heres what you should see now: a pipe ready to get air from that empty space behind the foglight
7. Now you put the fender liners back in (if you so choose, the airflow to the filter will be better without the liner but for those of us who are concerned about puddles i would put it back in. (you can always take it back out come summer time!)
8. Sit back and marvel at your accomplishment! you just make one of the more worthless parts ever on a subaru into something that makes your car unique!
