4728, Bosch Platinum 4s

Ne1 use 'em? I just put some in I can tell there is a difference. You guys know if they make platinum 4s one range colder? That would go great with my nitrous setup when I get it. Thanx

I heard those run waaay to hot for any forced induction/nitrous setup. Personally.. I don't see the significance of fancy spark plugs (beru, denso idridium) besides they're longitivity. You can't go wrong with regular NGK's with the proper gap.

NGKs are a good bet, there is nothing wrong with using them, but I just got some information from someone who used the plugs on an engine dyno, and at least for being NA they should help a little bit more. I haven't tried them myself, but I plan on it after the shootout.
