Now that i'm runnin higher boost what should I gap the plugs at .025 or just .030 and what type of plug do people recommend? I was always goin with coppers but 6-7 months ago I put in the factory NGK platinums cause the ngk coppers were having to be replaced like every 5-6,000miles or they would start leaking compression and having weak spark issues. I've heard platinums suck in turbo cars but these have worked the best so far and seem to be much more quality than the $8.00 coppers.

you spent 8 bucks on coppers? I hope thats for all four!

secondly, I'd give the iridiums a try, .028 gap.

yes $8 for all 4 but it doesnt matter anymore cause I tested my compression and #4 is at 40.

I thought iridiums aren't supposed to be gapped.
