Spark plug Autolite or Motorcraft
Reviews
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
I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.
Pros: success with autolite plug
Part number: AR52
switched to the back to the motorcraft spark plugs $15 a piece fixed it for a while
Pros: fixed issue temporarily
Cons: issue returned
Vehicle:
Ford
Mileage: 370148 km
I agree with everyone saying NGK but I would also like to recommend you do not buy an autolite if you need a substitute, they have horrible quality control.
Cons: horrible quality control
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
