Ford OEM coils rarely go bad. The red coil you had there was a cheap aftermarket replacement. You can pull the boots off the OEM coils and clean up any corrosion from the contacts. Replacement boots are available for cheap as well, if you have a boot with a tear or something.
MSD is not a cheap aftermarket part. After market yes, cheap no. Ive never had a single issue from a MSD part. Cant say the same for the oh so reliable ford ignition coils. Just saying...
Autolite spark plugs are terrible. I wouldn't put them Ina lawn mower. I've had more than a few cars roll though shop which just had new auto lites installed and IV fixed wm by replacing them with whatever is OEM
