Im currently using NGK bcpr7es 6282's and I have them gapped to .20 and im still blowing spark out. Should i try to gap them lower? these plugs not good? or my coilpacks are going out?

lol, ~380whp maxed, but if you haven't checked you could be going lean.kamikazemkiii;1548423 said:Around 4000+ When your supposed to be in boost, How much hp does the stock fuel system support?
