Thinking about replacing the plugs in my '04 GT2 and remembered hearing someone say a while back something about the platinum and iridium maybe doing some major damage to heads etc.
What is the recommended performance plugs for such a car or should I not worry about which onces I get since my car is not SC or doesn't have a turbo.
I was looking at the PLATINUM IR FUSION BOSCH plugs.
