Hey guys. I have an 08 4.6 with 60,000 miles and was going to change the spark plugs soon. Should I use the autolite double platinum or motorcraft single platinum because Ford no longer makes the double platinum
I don't know if it was in a 4.6 or a 5.4 but saw a thread recently on the Autolites where the tips were burnt off in just a few thousand miles. I'd look either at MC or Champions myself before Autolites.
