Spark plug quality
 

Had anyone had issues with Autolite spark plugs being absolute garbage recently?

I had 2 sets in my truck that barely made it 4000 miles before 4 left the chat in each set.

With First Brands falling apart, they're not likely to get better.

Go NGK.

2nd what Shifty One said. Lots of allegations of wrong doing by First Brands C-suite folks. Very possible that to keep the gravy train rolling, substandard(cheaper) ingredients were used in various First Brands factories. Autolite is a First Brands company. Last I read a few weeks ago, the bankruptcy plan for First Brands included shutting down the Autolite division.

Probably best at this point to pick a different supplier.
