Spark plug Autolite or Motorcraft
Reviews
Bought two auto light from autozone to fix a quick misfire. Used it for two years then took it out and saved it. Quick changed two with the auto light I had previously saved. And bought another one at autozone. 2 years later still running good. Gotten lazy to changed them out. But still running good in my 08.
Pros: long-lasting, reliable
Vehicle:
Ford
I have about 30k on my plugs (Motorcraft OE). I've no problem buying them again as they've held up great
Pros: great durability
Mileage: 30000 km
Autolite plugs work fine in my Toyotas.
Pros: work fine
Almost any spark plug is better than the Torch it comes with. The recomended is the NGK BP7ES, but is not made any more, many use the BPR7ES without issue, which is a resistor plug, but the manual specifically says to not use a resistor plug. I am using an [Autolite AR52 plug](https://a.co/d/7Z3keDh), it crosses with the stock Torch and NGK BP7ES and is a non-resistor plug. Many people hate Autolite plugs, but I have been using them for years in other vehicles and never had an issue, and so far it is working just fine in my 11500.
Pros: working just fine
Cons: many people hate
Part number: AR52
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
If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.
Cons: misfire after plugs
I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.
Pros: Engine light went away
Cons: runs rough, misfire
Homie, do not run Autolite plugs.
Cons: do not run
Most Asian brands are pretty picky about spark plugs. You put Autolites in a 70s malaise-era Ford - not in a modern, sophisticated, computer controlled, turbocharged Honda.
Cons: picky about spark plugs
Vehicle:
Honda
Autolite are garbage plugs. Get denso or ngk plugs and gap them accordingly before installation. You can see signs of blow-by at the porcelain.
Cons: garbage plugs, signs of blow-by
