Review on ACDelco 41-162 Iridium Spark Plug - Genuine GM Original Equipment by Charles Fowler

Revainrating 1 out of 5

Check release! for ignition parts

I installed this on a 2007 Chevy Tahoe LT (5.3), do yourself a favor and check the gap before you put it. Note that packages will be scattered during shipping. Some of the plugs I received had to be changed to .040. If you don't check them, you'll hate yourself later when you have to remove the spark plugs, especially the #8 spark plug.

Pros
  • GM engineers design and test genuine parts specifically for your Chevrolet, Buick, GMC or Cadillac vehicle
Cons
  • Hard to tell
