i just called my local ford dealer to get some spark plugs for my 00 gt and i asked for the following plugs...agsf-32c. He told me they are discontinued and they dont make them for mustangs, and that i have to use the double platinums witch are 10 bucks a piece from them. where can i find the copper motorcraft plugs. I dont like using autolite or anything else and i dont want the platinum plugs this time.
