I had the Cobra modded with a 2.95 upper and the breather mods and these plugs. I had them gapped to a little less than .35. I returned the car back to stock minus the plugs. Is that going to be a problem?
Dumb question. NGK TR6s and stock set up.

You should be fine. The colder heat range on the plug just reduces detonation from a hot setup, i.e. a pullied cobra.

The ngk tr5's were meant for a lower boost application while the ngk tr6's where meant for higher. Like he said, the tr6's have a colder spark and IMO i think you should be ok with a stock gap.
