i do believe that autolite is the equivalent to motorcraft as well

I'm not sure if autolite makes motocraft plugs but they are both the best to use in your car

[snake_bitten711]

Oh OK I usually hear bad things about autolights

Autolites don't work in most other cars but that goes the same for champions, they only work in chrysler products and ac delco only work in gm products. Every auto maker has a specific brand plug they use because it was made and designed to work specificly for their cars. Even though champion ac dellco and others make plugs that fit the ford cars that doesn't mean they will work well.
