Did you even bother reading the responses we posted in the thread you made yesterday about the exact same topic?

Those who are saying 1 stage colder have no idea what they're talking about. The reason you get colder plugs is to compensate for the extra heat generated by your supercharger when you drop pulley sizes.

Trust me, get the normal heat range. There's no reason to drop down one since you're not running any extra boost.

NGKs have had the best reviews from everyone who's tried em. They also have the benefit of being really cheap and easy to find.
NGK (6962) BKR6E - comparable to stock plug. Best for stock boost applications.
NGK (4644) BKR7E - 1 step colder (~3" pulley)
You'll want the 6962s. You can order them from Autozone (or whatever your local auto parts store is).
