NGK BR7HS-10 is a high-quality original resistor spark plug, developed for 2-stroke outboard engines and other petrol engines where a spark plug gap of 1.0 mm is required. The spark plug delivers a stable and powerful spark, which ensures reliable cold starts, smooth engine operation, and efficient combustion. The factory-set spark plug gap makes the spark plug ready for installation without the need for adjustment in most applications.
NGK is the world's leading manufacturer of spark plugs and an original equipment supplier to a wide range of engine manufacturers. The BR7HS-10 is equipped 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 trivalent plating makes the spark plug particularly well-suited for the marine environment.
The spark plug is used on, among others, several Yamaha 25 HP, Yamaha 30 HP, Yamaha 40 HP, as well as select Tohatsu and Mariner 2-stroke outboard engines where the manufacturer specifies the BR7HS-10 with a 1.0 mm spark plug gap. Always check the engine manual or the existing spark plug before ordering.
