Bosch Super are good plugs. The platinum plugs are okay if your rig is running well and you are willing to allow the plugs time to reach operating temps before drag racing the ricers. <img src="/forums/images/graemlins/wink.gif" alt="" /> I agree with Les, don't use the platinum plugs if you are having problems. they will just foul up.
