do this, your gap may be to wide, and junk those spark plugs, the fancy name and good marketing is what sells those, not performance in my opinion. i have had better luck with the NGK bpr7es, its a colder plug.
just wondering, do you have a boost controler (boost turned way up and not enough fuel to compensate =detonation) without the other needed items or some other messed up combo? also what octane are you running? cheap gas+boost+high revs=pits in pistons, so I've seen. has your car sat? and blah, blah, blah, blah???????????
