Re: spark plug question??

You need to use a non-platinum plug as the platinum plugs run hotter and can lead to pre-detonation. A lot of guys run NGK TR6's, they're one heat range colder than stock and gapped at about .035. I'm running Autolite 103's; 2 heat ranges colder than stock. Do a search in the Forced Induction section.

Depending on the amount of boost youre running the Autolite regular plugs (103, 104 etc) are nice.
