What do you mean? do bad spark plugs make a diff from good ones?> in that case hell yeah. SP Engineering Supra Widebody made 798RWHP on somewhat bad plugs. It makes over 850RWHP on fresh plugs. You tell me if it makes a difference. Get NGK 3330's if it still misses gap down to .030 if still, .028

Want to know a kickass cheap plug? Autolite cheapos #3924. The copper ones. A buck each. Gapped down to .032. A smaller gap than that will cause missing at low rpms, crappy idle. I put down 392hp/388tq on an *AUTO* with them. The only thing is that you should change them every oil change but don't go longer than 2 because they wear out fast. No biggie, they are a buck each.
