Spark plug Champion or Autolite

I now have the new plugs which are autolite gapped at .027 as it is suggested by autolite and also in the Bentley book.

The truck is currently using Autolite XP5245 iridiums. Normally I would go with something from NGK but I figured if the Autolites were a decent price I would get them and they would probably last the life of the truck

If its just painted like some cheap plugs such as some autolites then yes its needed.

Replace those plugs with nothing other than the Champion 7989 plugs. They are about $14 each and they are a 1 piece design.

Autolite 4162's, I changed them out every 1000 miles.

autolites were fine 100 years ago

now stick with NGK or whatever OEM was. its not worth it to be fudging around and what little your gonna save may be burned up in less MPG using some other plug.

I've had nothing but bad luck with Autolite brand.

I have a poor running Audi in the shop now. While it needs more than plugs, it has autolites.

the autolites are bottom of the barrel, i've only used them once when i was young and dumb and ofc they busted while trying to repair and remove after.

Yeah, get rid of those: autolite is junk.
