The NGK BR9HS-10 is a high-quality original resistor spark plug, developed for high-performance 2-stroke outboard motors and marine engines. The spark plug provides a stable and powerful spark, which ensures reliable cold starts, smooth engine operation, and efficient combustion. With a factory-set electrode gap of 1.0 mm, it is ready for installation in a wide range of Yamaha and other marine applications.
NGK is the world's leading manufacturer of spark plugs and an original equipment supplier to a wide range of engine manufacturers. The BR9HS-10 is manufactured with a copper core, a nickel center electrode, and a built-in 5 kΩ resistor, which reduces electrical noise and protects the engine's ignition and electronic systems. The corrosion-resistant coating makes the spark plug particularly suitable for the maritime environment. The spark plug is used on, among others, several Yamaha 225G 2-stroke V6 (1998-2004), Yamaha 250B V6 EFI (1997-2006), and Yamaha V6 Excel models.
