Review on ACDelco 5613871 Acdelco Spark Plug by Dave Hanson

When I tried this automotive replacement part it definitely failed to meet my expectations. It did not deliver the required amount of power, and the car was running worse than before.Although it was supposed to be a standard spark plug, it didn`t operate as effectively as the one I had before. The only positive thing about this part was the affordable price, but unfortunately, it didn't make up for its poor performance. Not recommended!
