·Just wondering because my friend has been using stock plugs and he is getting NGK3330's in a day. Just was wondering what the effects will be when changing, becasue I know nothing about Supras, (V8 man) but he keeps telling me that everyone recomends changing and that it makes a big difference. I told him that I thought it wouldn't do to much. But I wanted to hear what some experienced Supra owners have to say.
