Spark plug Autolite or BRISK

Stock is generally fine, however if your tracking or going through multiple heat cycles on your drives id recommend er12s from brisk. I run them and they havent skipped at beat. Intervals are shorter for changes.

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 use brisk standard temperature. Work great

I recently took my stage 2 43K mile b8.5 s4 apart and did the PCV, water pump, thermostat, new 2 step colder brisk spark plugs gapped to .25. I took the spark plugs out and noticed heavy carbon and the ground electrode was white, even on all plugs . (20 miles on plugs)

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.

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.
