Upgrade your engine’s reliability with the Autolite Copper Spark Plug 4303, designed to deliver consistent ignition and superior performance. Its full copper core, paired with a copper-glass seal, ensures maximum voltage reaches the spark gap while maintaining a 100% leak-proof, gas-tight seal. The multi-rib insulator minimizes the risk of flash-over and the one-piece terminal post adds strength for durable, long-lasting use.
Engineered for all conditions, the 4303 features a cold-formed steel shell with precision-rolled threads and a built-in resistor to reduce radio frequency interference (RFI) and protect against electrode erosion. This spark plug provides reliable combustion, smoother engine operation and improved overall efficiency. Always verify cross-reference listings before purchase to ensure proper fitment. Available at Cheetah’s Powersports for riders who demand dependable performance.
