NGK V-Power Spark Plugs (LFR4A-E) feature a unique "V" cut in the center electrode that helps direct the ignition spark to the edge of the electrode to increase ignitability and reduce quenching. Engineered for the marine environment, these plugs feature trivalent metal plating for superior anti-corrosion and anti-seizing properties. Proper heat transfer and durability are ensured by the NGK pure alumina silicate ceramic insulator, protecting your engine from breakage and misfires.
