With my current mods, what spark plug do you recommend? I was thinking Denso ITV22, due to the positive reviews and the fact that they are pre-gapped to the stock height (~0.30), but I wasn't sure if I need a one step colder plug with my current mods. The problem with the Denso ITV20 which is standard heat is they come pre-gapped at 0.44 and I am concerned that I will break them trying to get them gapped to 0.30. Has anyone had success re-gapping this plug to 0.30? Do you recommend I just go with a one step colder plug? BTW..I have 32K on my car if that helps. Thanks in advance for the help!
