The most common and best performing plugs for our cars as follows.



Non-supercharged- Autolites or NGK platnums or copper. Does not matter.

Supercharged- Autolites or NGK. Copper only.

Hey tdc, whats wrong with platinum's with the supercharged engine? i just put in autolite dbl platinum 605's a couple weeks ago. I don't drive the car in the winter so changing them again would not be a problem. While i'm asking questions, would 104's be better with my mods or are the 605's fine? one more question. I am thinking about buying a 3" used zzp resonator, is it worth my money? would it do anything for the car or should I keep the stock res? the remainder of the exhaust would be left stock. I also go to lake placid a couple times a summer. should set up a grand prix forum trip!

copper plugs help the most with knock reduction. they wear out fast, but they are also cheap as crap.
