The NGK BPR6EFS is a high-quality original resistor spark plug developed for inboard engines, marine petrol engines, and selected outboard motors. The spark plug delivers a powerful and stable spark, ensuring quick cold starts, smooth engine performance, and efficient combustion. The projected insulator and tapered seat provide high operational reliability and reduce the risk of fouling – even under demanding maritime conditions.
NGK is the world's leading manufacturer of spark plugs and an original equipment supplier to a wide range of engine manufacturers. The BPR6EFS features 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 tapered seat ensures a proper seal on engines designed for this type of spark plug.
The spark plug is used on, among others, several MerCruiser 3.0L, MerCruiser 4.3L, MerCruiser 5.0L MPI, MerCruiser 5.7L EFI, MerCruiser 350 MAG, MerCruiser Scorpion, Volvo Penta 4.3 Gi, Volvo Penta 5.7 Gi, and a range of other marine petrol engines. It replaces, among others, Mercury OEM 816336Q / 8M0176613 as well as several Volvo Penta OEM numbers. Always check the engine owner's manual or the existing spark plug before ordering.
