Review on 🔥 ACDelco GM R44LTSM Spark Plug: Genuine Original Equipment for Optimal Performance by Harel Leary

Revainrating 5 out of 5

but it works fine.

I've never been able to find a unique factory spark plug part number and correct gap in my '00 Silverado 2500 6.0L, but the center electrode on it is about 500 times thicker than other part numbers I took off . Haven't found any problems with the spark plugs and the engine runs at least as good as the other spark plugs. The spark plugs I took out ranged from .055" to .070" with a .045" gap between them. I don't know if that's correct or not, but it works fine.

Pros
  • Black Onyx coating helps reduce corrosion
Cons
  • -
