NGK copper 2 step colder than stock. Get the place to do a cross reference for the exact part number. The standard V-power NGK plugs seem to be the popular choice. Thats what I running with spray.

I agree... I ran colder V-Power NGK's with the Lightning, and liked them. :dontknow:

Are there any plugs that improve power at all if you are pretty much stock?

Thanks...I am just wondering if they are fouled already...My A/F at WOT used to be 10.5-10.6. Now it's 10 or according to my wideband....well I think it's below 10 cause that is the lowest the meter will go...
