NGK V-Power Spark Plugs, model BKR4E-11, feature a unique v-cut center electrode design that enhances spark development for improved ignitability and reduced quenching. They are equipped with trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, a pure alumina silicate ceramic insulator for strength and heat transfer, a copper core for efficient heat dissipation, and triple seals to prevent leakage.
