When you buy your spark plugs buy a gap checker too..there an on the counter kinda item..before you put the plugs in make sure the gap of the plugs match what the book sais (dont know it off hand) just in case the plug was dropped or something during shipment you dont f your engine up

They are already gapped, but not to the VQ30's specs. If you buy NGK Platinum plugs, there is no need to gap them as they are already up to spec for our engine. Out of curiousity, why are you using the Coppers instead of the Platinums?

only advantage I see with plat is the extra 30k of life, but were enthusiests anyways so its no big deal changing coppers out at 25-30k. Copper is way cheaper in the long run and offers better sprark.
Platinum isnt recommended for nitrous also.
