Review on ACDelco 41 124 Professional Iridium Spark by Abidzar Olivas

Revainrating 1 out of 5

Worst Spark Plugs Ever!

After trying this product, I'm convinced that ACDelco should stick to making other automotive parts. These spark plugs were a complete waste of money .Not only did they fail to improve my engine's performance, but they actually made it worse..

Pros
  • None
Cons
  • Made engine performance worse.
