What's wrong with non-Motorcraft spark plugs?
#1
#2
I had bought a new set of Autolite Double Platinum for my 302ci and before installation I became concerned after reading the hate for them so I bought a set of Motorcraft. Compared both physically (electrode and insulating post length) and decided to run the Autolites. The engine ran beautifully. I've run Autolites in everything I've owned since 1974 and no complaints.
