    Motorcraft-Autolite spark plugs for FI?

    Anyone using them?

    If so, how good are they?

    Part number-model?

    ive been running the autolite ar-3911 in mine, work great. But they are for the tfs heads. dont think they will work on stock style tapered plug heads.

    The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
