Description:
The Autolite Copper Spark Plug 86 is engineered to support quick starts and dependable engine performance for vehicles and applications that use a standard-design spark plug. It features a copper core center electrode to aid thermal control and improve resistance to fouling, helping maintain consistent ignition under normal operating conditions.
Built with high nickel alloy center and ground electrodes, this plug is designed for extended service life. A high alumina multi-rib ceramic insulator provides strong insulation and thermal conductivity, while the nickel-plated shell helps resist corrosion for added durability.
