What gapping??

well it depends. I have my NGK 3330´s gapped at .028" on pump gas boostin 18 psi with no problems i think that my car should be around 550rwhp at that boost. People usually say that .026" - .028" works well for them at that powerlevel


i would probably gap mine at .022" - .024" on high boost and race gas that should be around 720-800rwhp but haven´t tried race gas yet
