ok, here is the thing about the sparkplugs you all are using. there are designed for a large gap, .050 or more. now when you close that gap below .040 you DO NOT have a flat gap across the center electrode because the ground strap is taller for the wide gap plugs, so it may appear to be .032 or .038 but if you look at the rear of the ground strap you'll see it's "humped up" (for lack of a better term) so a .040 to .044 gap will give you a pretty close to flat gap across the center electrode and ground strap and a better more uniformed spark and the factory ignition system will have NO problem wth it, (S/C or Turbo cars are a different animal). also that small gap(.032 to .038) on a Nytrous car when driven on the street will suffer from poor performance and poor gas milage. Oh and NEVER use Platinums in a power adder engine for any reason, I dont even like plats on the street, seen to many problems wth them
