Fomoco plugs are actually pretty good. I replaced my Ford Escape with some more expensive Bosch and had misfires immediately. Got some Fomoco’s from O’Reilly and haven’t had an issue since.
Fomoco is ford.. it's oem 10 years is a good run. Yes they fail and get stuck closed, I've had the fail and the spring grenades the housing also.
I have many issues with fomoco products when replacing alternators. If not oem they tend to crap out quickly or not work altogether.
