The NGK TR4 V-Power Spark Plug is engineered to optimize ignitability and performance with its innovative v-cut center electrode design. This design directs the spark to the edge of the electrode, accelerating spark development and reducing quenching for reliable ignition in a variety of engine conditions. The plug is equipped with trivalent metal plating to resist corrosion and seizing, ensuring longevity and reliability. It also features corrugated ribs to prevent flashover, a pure alumina silicate ceramic insulator for robust strength and efficient heat transfer, and a copper core that aids in effective heat dissipation. Additionally, triple seals on the plug prevent leakage, making it a dependable choice for maintaining engine efficiency and performance over its service life.
