Spark plug Autolite or OEM Honda

Got my 2019 Civic 1.5T to 93k miles and sold it this fall. Great car. Probably had some oil dilution because dipstick level would creep up. No CVT problems (drain and fill were done at 45k & 90k). Replaced plugs at 90k as well and they looked good although there was a little oil in cylinder 3. Ran great, no codes, high quality oil changes every 5k.

On my Honda Fit that would be an excellent price because you have to take off a cowl to get to the plugs.

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.

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

Only things other than oil changes and brakes have been spark plugs at 100k and 200k, fuel injector at 120k, transmission fluid at 200k, and ac compressor clutch at 230k. 2012 automatic

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.

Dont use autolite garbage, this isnt uncommon with cheap plugs. Get NGK Iridums

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?

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.

Homie, do not run Autolite plugs.
