Spark plug Autolite or BERU

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

I have the beru side firing and they work just fine.

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

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

As long as it’s not auto lite plugs you should be good. I’ve seen those things hinder 3 separate rigs from running right. Once one cracked 100 miles after installing them, half way through a trip we had to sop at autozone and replace plugs

Don't even think the Autolite or Bosch last as long as Denso/NGK spark plugs.

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.
