Autolite 85 Copper Resistor Spark Plug
Delivering reliable spark under high load and extended operation, the Autolite Spark Plug uses a copper core center electrode to quickly transfer energy and manage thermal spikes. The high-nickel alloy center and ground electrodes extend service life, while the side electrode maintains gap spacing by resisting electrical and chemical wear. Its high-alumina multi-rib insulator prevents flash-over, and the nickel-plated shell guarantees long-lasting strength. All of these features come together in a copper resistor design suited for legacy engines and utility vehicles with a 13/16-inch hex plug. Order the Autolite 85.
