Review on πŸ”Œ ACDelco 41-100 Iridium Spark Plug | GM Original Equipment by Jon Hill

Revainrating 5 out of 5

Good spark plug OEM

Spark plug already set at the factory. This is the factory spark plug that the car recommends for a 2007 Chevy Impala 3.5 engine. The plug works great. Installing those on the back of this engine is a nightmare. Connectors are difficult to remove and there is no room for a firewall. At least they last 100,000 miles or more there. Happy with it and the engine runs well.

Pros
  • Iridium enables small, efficient electrode designs for reliable cold starts and fast acceleration
Cons
  • ---
