What plugs are you guys running with your supercharged MM's?

I would like to go platinum, which is what I have now. NGK V series. Can I just re-gap them?

You really shouldn't gap platinum plugs. You can damage the platinum tip.

I believe there is a special tool for that.

May I ask why you like those Doomy?I use them, too. Some of the most knowledgeable people recommend them for Trilogy cars, but I can't say they'd be the best choice for all supercharged applications.
