Top 10 Best Boat Engine Spark Plugs

NGK BU8H surface gap plugs feature a semi-surface discharge design to improve ignition and burn off any carbon before it can build up to foul the plug. Check your engine owners manual for the correct spark plug and use only the plug as recommended by your engines original equipment manufacturer. NGK Trivalent metal plating also provides superior anti-corrosion in the marine environment and anti-seizing for easier removal. The copper core aids in heat removal to keep the spark plug operating efficiently. Spark plugs are easy to change with common spark plug sockets..

NGK BUHW-2 surface gap plugs feature a tungsten center electrode and a solid terminal. Check your engine owners manual for the correct spark plug and use only the plug as recommended by your engines original equipment manufacturer. NGK Trivalent metal plating also provides superior anti-corrosion in the marine environment and anti-seizing for easier removal. Dont just clean used spark plugs, replace them with new plugs for better performance. Replace all the engine plugs at the same time.
