Ok here is a question for you guys, on the motorcraft plugs. My 2000 SVT came with AWSF 32F. These plugs worked great. When I pulled them at 35,000 they were still in respectable shape. I replaced them with the APP 764's. IMO these plugs were terrible. As I stated before, I had two of these arc through the ceramic and kill themselves within 2000 miles after installing them. I went to the Autolites based on people's experience with them here on the CEG. After my experience with them, I decided to go back to the Motorcrafts. The parts guys at my local stealership supplied me with AGSF 32FM. Obviously they are different from the original plugs. The only visible difference between the two Motorcrafts is the extra threading on the AGSF 32FM's and the lack of a black coating. They seem to be working just fine in the tour, but maybe you guys have some other info that I am not aware of. Are these safe to be using or should I go back and get the original AWSF 32F's?
