The NGK Standard Spark Plug is precision-engineered to deliver dependable ignition performance across a wide range of engines, including marine, motorcycle, ATV, snowmobile, and outboard applications. Built to meet or exceed OEM specifications, this plug ensures consistent starts, smooth operation, and long-lasting durability.
Manufactured with a high-grade nickel alloy electrode, it provides stable spark delivery and excellent wear resistance. The durable alumina silicate ceramic insulator enhances dielectric strength, reducing the risk of misfires and improving combustion efficiency. A triple-gasket sealing system prevents combustion gas leaks for cleaner, more reliable performance over time.
The solid copper core ensures superior heat dissipation and optimal electrical conductivity, maintaining efficiency under demanding conditions—from cold starts to extended high-load operation. Trivalent metal plating on the shell protects against corrosion and seizing, allowing easier installation and removal while extending service life.
Designed as an actual OE or direct-fit replacement for select Yamaha WaveRunner models (1988–1997) and other compatible engines, the NGK Standard Spark Plug combines proven technology with robust construction for reliable ignition performance in any environment.
