I'm going to be changing out my intake this weekend (the polished one), and taking the opportunity to change out my plug wire and spark plugs while I'm at it. I went to my builder to ask him what plugs I should use. He told me to use the NGK BKR7E11. I believe that they are 2 step colder than the stockers (not sure), but when I went to check what application they are used for the Viper 8.3L doesn't come up. Do any of you guys know will these plugs fit on our engines? And are they 2 steps colder?
