Ensure dependable engine performance with the Autolite Copper Spark Plug 4163, engineered for consistent ignition and long-lasting reliability. Its copper-glass seal bonds the insulator, terminal post and center electrode together, providing a 100% leak-proof connection that delivers full voltage at the spark gap. The multi-rib insulator reduces the risk of flash-over, while the one-piece terminal post adds strength and durability. With a built-in resistor to minimize radio frequency interference (RFI) and prevent electrode erosion, this spark plug keeps your engine running smoothly under all conditions.
Built with a full copper core electrode and a cold-formed steel shell with precision-rolled threads, the Autolite 4163 ensures optimal fuel combustion, reliable starts and consistent power output. Perfect for a wide range of vehicles, it combines performance, efficiency and longevity in one trusted spark plug. Be sure to verify all cross-reference listings before purchase to guarantee the ideal fit.
