To clarify something:
the "ford platinums" (aka Motorcraft doubleplatinum "ppm" not "fm" part number) are the SAME THING as Autolite APP764's.. not better..
someone stated that ford's are better, but autolites are a few dollars cheaper... autolite MAKES the motorcraft plugs.. identical plugs.
and 0.054 is the correct gap, yes.
