Great price! High quality! Confident will last!
I was quoted a much higher price for this same product at my local auto parts store. I was so relieved to find them much cheaper here. High quality and fit my vehicle just like it said!

but it's working fine.
Never found a clear part number for the factory spark plug nor proper gap in my '00 Silverado 2500 with 6.0L, but the center electrode on these is about 500x thicker than the ones of a different part number I took out. Haven't noticed any issue's related to the plugs and the engine is running at least the same quality as the other plugs. Plugs I took out varied from 0.055" to 0.070", gapped these at .045". No idea if it's right or not, but it's working fine.

As expected
Just as expected. I still had to gap them, I expected that. I've had them installed for some time now and they work as expected. Personally I've tried many different "high performance" plugs and NEVER found any benefit in any way. These are priced right and oem specs.
