The NGK BPZ8HN-10 is a high-quality original resistor spark plug, developed for Mercury and Mariner 2-stroke outboard motors with CDI ignition. The spark plug delivers a powerful and stable spark, ensuring fast cold starts, smooth engine operation, and efficient combustion. The factory-set electrode gap of 1.0 mm 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 BPZ8HN-10 is equipped with a copper core, nickel center electrode, and Z-type inductive resistor, which effectively reduces electrical noise and protects the engine's ignition and electronic systems. The corrosion-resistant coating makes the spark plug particularly well-suited for use in maritime environments.
The spark plug is used on, among others, several Mercury 20 HP, 25 HP, 30 HP, and 40 HP SeaPro 2-stroke outboard motors from the 1990s and 2000s. Always check the engine owner's manual or the existing spark plug before ordering.
