Replaced my factory AC Delco plugs

Replaced my ACDelco ones. Autolites are always a good value and the iridium tip is smaller than the competition. I've never had a bad plug from Autolite and have been using them for years in multiple vehiclesRead full review...

Okay. They're spark plugs.

All good. Gap quite a bit off out of the box. Efficiently shipped.
