Description:
The Autolite 2976 Copper Spark Plug is engineered to deliver reliable ignition performance, quick starts, and consistent engine power. Its copper core center electrode provides excellent thermal conductivity, helping maintain optimal operating temperatures and reduce the risk of fouling.
Durable high nickel alloy center and ground electrodes help extend the life of the spark plug while maintaining consistent spark delivery. The high alumina multi-rib ceramic insulator improves electrical insulation and heat dissipation, supporting stable performance under demanding engine conditions. A nickel-plated shell resists corrosion and helps ensure long-lasting durability.
Autolite copper spark plugs are designed to meet the performance needs of many gasoline engines, making them a dependable choice for routine maintenance and replacement.
