NGK SPark Plugs

[subaruhunter]

Have a: 98' Subaru Legacy Outback

Dealer says spark plug $13.25 each are part number FPR5b-11 which as laser NGK plugs

O'Riely's Auto part store sells 2 style of NGK:
1. OE compatible P/N 2300 Laser Platinum NGK Plugs...$13.50
85,000 mile rated
2. P/N 7090 G-Power NGK Platinum plug $3.00
50,000 rated


can I use the G-power NGK plugs as the dealer stated anything non-OE in a DOHC engine could cause damage.

I would never skimp on plugs or wires. I'm sure they will work but our cars are fairly picky about ignition parts and the laser platinum are what you would get if you bought dealer plugs. I've read plenty about people getting misfire CELs from cheap plugs and wires. I use the laser iridium plugs only and have used denso iridium in the past when I was trying to save some money. If you're interested, I have some Iridium IX plugs that a family member purchased on amazon for me by mistake if you want a good plug for and still save some money. It has a shorter life span but they are NGKs performance market plug. I didn't use them just because there are more fun things in life than changing plugs on the EJ25D.

NGK Copper V-power runs 1.99 a plug. That's generally what I've seen recommended for the 90s Subarus.

yeah the only real advantage to the iridiums is that you don't have to change them as often as the cooper. Are the lasers the new name for the ngk iridiums? Those were around $7 a piece when I changed out the sparks plugs a couple of years ago...

im a NGK V-power guy myself, just change them every 15k. An expensive plugs only works so long as it stays clean, if it gets covered in junk in 20k its done anyway. Copper is still the most conductive material, it just wears quicker than the others which is why they have a shorter operational period.

checking www.sparkplugs.com (http://www.sparkplugs.com) , it looks like NGK BKR5E-11 is what i would get for you car, most local parts stores will have them for less than $3 a piece.

For you guys running single cams, use what ever makes you happy... They are easy to change. However, there is a reason Subaru uses a specific plug for each motor.

If you buy cheap plugs for a twin cam, I'll be blunt and say you're stupid! Even with the Platinum plugs Subaru recommends for the EJ25D's, they are said to be changed every 60K. I get my customers and even my own plugs from Subaru, that way I know I'm getting the right heat range and style. Also it helps I'm a shop and no one can beat the price at Subaru.

In short, if you're doing plugs in a Subaru, get the right ones. I dont know about you, but I dont mess around with twin cam N/A 2.5's. They are picky motors and I'll do what I can to prolong maintenance if possible with the right parts.

[subaruhunter]

good point.

DOHC intimidates many mechanics......and I keep getting inconsistent recommendations from different Subaru specialist garages and Subaru Service personnel.

Oh, when I say "I dont mess around with 2.5's" it means when I work on them, I get the right parts. I love working on them! I just never split the blocks, but other then that, I love it when a customer says they want HG's done.

Those motors get OEM Subaru headgaskets and Subaru NGK's... The rest is what ever they want to pay for...
