just got it today :wink: still waiting for my godspeed big maf before i get everything installed.. bought everything from adam - z1 performance my goal is about 430 -450 crank hp.. hopefully this set up with my other supporting mods will bring me to low 12's to high11's

 

I'm jealous, I wouldn't use those spark plugs on an STi though.

 

yes pe1820 turbo..

how come i cant use the denso plugs?? its made for the 2004 sti( 1 step colder) it has the longer tip compare to the regular wrx with the shorter tip?

 

these are the right plugs for the 2004 sti.. got the info from nasioc.com =)

 

I've seen a few engine failures due to those plugs only, when you ping at all, they get covered in that spall stuff and because the tips are so small they can get covered and won't fire. But, it's your car. I just know that most of the top tuners in Japan use the stock plugs on most models of cars. Even Mr. Spoon himself uses stock Dino oil in his cars.
FWIW,

thanks for the heads up.

 

If you go to Nabisco there's a few threads about those plugs, one is even from Nathan at Turbo XS pleading with people not to use those plugs. One of the real big problems (not including the ones that are too short) is the pitch of them, that spark can blow out, they're great for a 13-1 honduh engine running boost but not for our cars that get too much fuel and have much bigger pistons. You can use them but I really would advise against it. But congrats on the rest of the parts, you'll be smoking vipers in no time.
