there's nothing wrong with platinums if you're going to keep your engine stock. If you're spraying Nitrous or Turdo/Supercharged, it's better not to run the platinum due to detination. Platinums tend to burn the buttons off of the strap and the tips will melt. Been there, done that! LOL

hell i've ran both ngk tr55ix and stock irridium plugs and i have found with my set up the stock ones work just as well as the ngk's.
