NGK B7HS is a high-quality original spark plug, developed for 2-stroke outboard motors, personal watercraft, and other gasoline engines. The spark plug delivers a powerful and stable spark, ensuring quick cold starts, smooth engine operation, and efficient combustion. Its robust construction and effective heat dissipation make the spark plug suitable for both recreational and professional use under demanding conditions.
NGK is the world's leading manufacturer of spark plugs and an original equipment supplier to a wide range of engine manufacturers. The B7HS is manufactured with a copper core and a nickel center electrode, which ensures optimal heat dissipation and a long service life. This is a non-resistor spark plug and should therefore only be used where the engine manufacturer specifically prescribes this type. The corrosion-resistant trivalent coating protects against rust and makes the spark plug particularly well-suited for the maritime environment.
The spark plug is used on several Yamaha 2 HP, 3.5 HP, 4 HP, and 5 HP 2-stroke outboard motors, as well as a wide range of Johnson, Mercury, Mariner, Suzuki, Tohatsu, Force, and Sea King engines, where NGK B7HS is the recommended original type. Always check the engine's owner's manual or the existing spark plug before ordering.
