Spark plug OEM FORD or Autolite
I've been running autolite in pretty much every domestic that comes through my shop for years since they’re usually the workhorse for Ford and GM tunes. Also, I haven’t seen any dip in the plug quality lately so that's a good sign. The iridiums are still pulling clean gaps right out of the box.
Pros: clean gaps, good quality
Vehicle:
Ford
I have a 3.5 ecoboost. All 6 of my Ford plugs failed because of cracks. I replaced them with AutoLite iridium XP5863. They are all still going strong after over 50k miles.\n\nThe Ford plugs failed with a cylinder misfire error code. The engine would also bog down under havy accelaration
Pros: still going strong
Cons: cracks, cylinder misfire
Mileage: 80467 km
Part number: XP5863
I changed my coils and spark plugs and it fixed this same issue
Pros: fixed same issue
Vehicle:
Ford Focus
I had this 8 months ago in my FG
New spark plugs and coil packs fixed it.
Pros: fixed the issue
Vehicle:
Ford
It\u2019s true that you dont\u2019 get quite as good performance as with the Bosch, but this is my second set of autolites and I\u2018m over 200k miles already.
Pros: high mileage, second set
Cons: not as good performance
Vehicle:
Volkswagen
Mileage: 321869 km
Just replaced all my spark plugs that were in for 83k miles. Autolites were in and replaced with Denso twin-tip.
Mileage: 133575 km
Dont use autolite garbage, this isnt uncommon with cheap plugs. Get NGK Iridums
Cons: cheap plugs, not uncommon issues
Pulled the spark plugs and #3 has burnt away the centre electrode. Plugs aren't all that old. Plug brand is Auto lite. Any ideas on what may be the cause?
Cons: center electrode burnt away
Vehicle:
Nissan
A quick search shows that autolite spark plugs don't seem to perform well in modern vehicles, you might have to go for a higher quality closer to OEM quality plugs.
Pros: higher quality, OEM quality
Cons: don't perform well
Homie, do not run Autolite plugs.
Cons: do not run
