Spark plug OEM Toyota or Autolite

Autolite Spark plug

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

Autolite Spark plug

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

Pros: long lifespan, good durability
Vehicle: Toyota
Mileage: 193121 km

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.

Autolite Spark plug

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

Autolite Spark plug

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
