I have three questions.....I read on the other forums Scott from FM recommending NGK Vpower plugs...
1) do any of you use these plugs?
2) Modern Performance's site says they may not work with MSD plugs....is this true?
3) Am I better off getting Iridims?
Yeah you are right good point. Right now I have ngk iridium colder plugs on my car. they were great but im trying to figure out that issue im having so i might as well get a new set of plugs while im at it. I just want to pick them up from pep boys though ( i dont think they have ngk iridium?)
4306 = Vpower btw...i just realized that. I bought them at autozone... fixed my problem.
tried to older sets of plugs...both same issue...one new set of plugs and my car runs great again lol.
