Alright, I am about to do a plug change. I want the best of the best! I was thinking AC Delco platinum plugs, but I haven't shopped spark plugs that much (this is my second vehicle, the first was a diesel, I haven't the slightest clue on spark plugs, except on how to change them.) So what are you guys running? What have you run previously? And why are you running what you currently are?
