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.

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

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.

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.

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

Probably going to need to pull them again within a couple years. Autolites are the absolute worst sparkplugs.

If you need new spark plugs... Don't use Autolite.

Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.

Throw those autolite plugs in the garbage where they belong

Yea,get some ngk’s or denso,autolite plugs are garbage.
