ACDelco Iridium Spark Plug, 41-110
An ideal plug for vehicles requiring platinum performance or older vehicles calling for conventional plugs, this ACDelco Iridium Spark Plug can give up to 100,000 miles of service in some applications. It has an iridium tip for maximum resistance to spark erosion and the corrosive combustion chamber environment to ensure lasting performance. These platinum spark plugs feature a one-piece integral suppressor seal that meters spark plug energy to help provide long electrode life. This one-piece configuration also seals against compression leakage. The spark gap of the 41-110 ACDelco spark plug remains virtually unchanged during the life of the plug for increased fuel efficiency.
