• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Which plug for a 3.5?

Scanned the car today, and it only ran 3-4* KR. I don't think that is too bad for no other mods, this is even on the stock spark plugs. But I did convince him to do a U-bend delete and a 3" DP. I realize that 4* is worse than 0*, but it is not as high as I was expecting.
 




Yes, we did some WOT runs. Headers will not be happening. This is his DD that is supposed to be for gas mileage. He just wanted the pulley so he could put the smack down on a modded SI. He wont stop running his mouth, so he wanted to shut him up. He rarely ever brings it into boost anyways.
 
I'll let him know! HAHA, he'll never do it. He put the headers in my GTP and nothing fit right. Plus he doesn't have alot of money just sitting around to spend. Oh, and another thing is he wants it to be more of a sleeper, so not that loud.
 




Just clarifying. Not saying you guys are wrong, but I read somewhere else on this forum that if you are running between 6 and 12 lbs of boost to run a .050 gap. he is peaking at ~11.5lbs
