LFR6A-11 V-Power Spark Plug | NGK 3672

Outboard engine manufacturers like Yamaha and Mercury use the NGK LFR6A spark plug as an OEM part to give boat owners the dependable premium performance they need. The nickel electrode has a V-cut grooved design to help generate the spark faster than regular nickel plugs. The engine fires right up and requires less voltage to burn the air-fuel mixture, meaning better acceleration and efficiency. It has trivalent metal plating to resist corrosion and triple sealing so no combustion gas leaks. A solid copper core and alumina silicate ceramic insulator manage heat levels.

NGK 3672 V-Power spark plugs are an economical way to maintain the factory performance of your outboard motor. It is a direct fit for many Yamaha 4-cylinder, V6 and V8 engines; check the owner’s manual to see if the plugs are compatible. Each NGK LFR6A-11 spark plug is rated for up to 30,000 miles or one season of use and has cold-rolled threads for easy installation and removal. We have these plugs in stock at warehouses across the U.S. for fast shipping coast to coast.
