Spark plug Autolite or OEM Mazda

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

OEM Mazda Spark plug

I’ve had my cx5 since August of 23. Put 48k on it since owning it, bought used at 44k it’s been a dream come true. cx5 just takes regular maintenance like oil changes spark plugs and brakes..and another plus it’s a very sharp looking vehicle inside an out.

Pros: sharp looking vehicle
Vehicle: Mazda
Mileage: 77249 km

OEM Mazda Spark plug

That price at 63.5k miles isn't bad imo. I spent roughly that same amount for my 2017 back in 2019 with around 40k miles (64k km). What's the service history look like? Have spark plugs been replaced, belts checked, engine oil changed at least 10-12 times by now? How are the pads and rotors?

Vehicle: Mazda
Mileage: 102200 km

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

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
