So I just got my supercharger and I'm looking to change out my spark plugs. Right now I'm the running NGK Iridiums but I'm looking for the right ones to run with F/I. Is it one step colder or two steps colder? I've only seen Bosch making them for an LS and not NGK unless someone knows a part number for the NGK LS ones. Also what gap should I be at, Ive seen people gap it anywhere from 24-33 but so some input on that would help. THanks:D

NGK BRK7E

Personally, I'd start with my gap on the narrow side of the range.

You'd better be taking notes. You'll need this info when you buy the kit I have for sale!
