I just switched to the 2.8 pulley and aux idler kit. I have a sct tune for 6# of boost. Car is running great with no detonation that I can notice. Do I need to change the spark plugs? if so what type should I use (gap, brand, range)? thanks

I suggest getting some plugs that run a couple of heat ranges cooler, I beleive NGK puts out a good one for boosted motors (TR6 or TR7). The Denzo IT22's are also a good choice, make sure you gap them between .032 and.038 for a cooler spark. You can gap your stock ones to .038 for a cooler spark also. The stock ones are supposed to be gapped between .042-.046 however, just about all of mine were gapped .050. Once I switched plugs my motor ran noticably smoother.

Some of the NGK TR6's have had issues with spark blowout in the past, but others have had great luck with them. I haven't heard any complaints about the Denzos.

Grey03Cobra~ Do you have any more pictures of your Cobra? I'd like to see the stripes/engine bay up close.

This is the only picture I have access to right now (I'm currently in Iraq). I have added some 18" Dezenyo Vapor rims since this was taken.

Thanks for the info i'm going to get the ngk tr6's. My tuner said to gap at .035. Does anyone know a good link with some pics for installation?
