Spark plug OEM FORD or Autolite
Since spark plugs don’t cost that much I played around with a few. My 05 TJ like the Autolite APP985 the best. Hated the NGK ZF5RN the most.
Pros: Autolite APP985 the best
Cons: Hated the NGK ZF5RN
Vehicle:
Jeep
Cylinder Misfires started on #2, progressed to all, replaced all spark plugs and all spark plug wires. Cylinder misfires now gone. Spark plugs and spark plug wires all in bad condition
Pros: cylinder misfires gone
Cons: spark plugs in bad condition
About 6 weeks ago I finally changed the spark plugs. So I put somewhere near 180,000 miles on a set of Autolite spark plugs. Two of the spark plugs the center electrode was completely gone. I don't know how the fuck the engine ran and I certainly don't know how it did not throw a code , it still ran very smoothly even at idle.
Pros: ran smoothly even idle
Cons: electrode was completely gone
Vehicle:
Ford Ranger
Mileage: 289682 km
I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.
Pros: work the best, long-term use
Vehicle:
Volkswagen Jetta
2013 3.5 hitting 170k miles within a few days. Second owner so not sure how it was maintained during it\u2019s life but I\u2019ve done 10k miles so far, needed a waterpump and sparkplugs but it\u2019s pretty normal wear and tear
Pros: pretty normal wear
Vehicle:
Ford
Mileage: 273588 km
Probably going to need to pull them again within a couple years. Autolites are the absolute worst sparkplugs.
Cons: absolute worst sparkplugs
If you need new spark plugs... Don't use Autolite.
Cons: Don't use Autolite
Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.
Cons: Autolite plugs are junk
Mileage: 200000 km
Throw those autolite plugs in the garbage where they belong
Cons: autolite plugs in garbage
