What spark plugs are you guy's using with the aluminum TA SE Stg. 1 heads? I apparantly was using the wrong plugs in mine for the past 2 years :spank: . I need a long shank, gasket seat plug with a colder heat range.
Dom, TA recommends the NGK BP4ES, BP5ES, BP6ES, BP7ES, BP8ES, or BP9ES. As the #'s go up, the plug is colder. I think most people are using the 6 heat range, I might be mistaken, but those are the correct plugs for the TA Aluminum heads.
