I myself have seen a couple autolite plugs break over time. Just me. In my younger days, I was always about NGK and other performance plugs, but truthfully now, I have seen better luck with OEM plugs. Just my :twocents: .
Champion plugs have worked well for me in my Jeep. Good old fashioned copper electrode truck plugs. Platinum plugs are a waste of money for a Jeep. I have tried many different manufacturers and styles over the years. I have never had a plug failure and I do a bunch of solo wheeling. I bring a full set of spares just for back-up.
Just put standard champion plugs in it, change at scheduled maintenance period. Chrysler uses champion as OE, GM uses ACDelco, Ford uses Motorcraft and so on.
Motorcraft=champion. I used to work for Advance Auto Parts corporate. Basically anything with a manufacturer name brand is some other brand. Check out a company called Mann & Hummel. They own most of the major filter & parts brands like Fram. Basically stick with the names you know.
