Description:
The NGK TR5 V-Power Spark Plug is engineered to provide reliable ignition performance and improved ignitability over standard nickel spark plugs. Featuring NGK’s signature V-cut center electrode, this plug helps direct the spark to the edge of the electrode for faster spark development, improved flame travel, and reduced quenching. This design supports more consistent starts, smoother idle, and dependable combustion performance in a wide range of engines.
Built with a copper core for efficient heat removal and a pure alumina silicate ceramic insulator for strength and thermal transfer, the TR5 is designed for durability in demanding operating conditions. Trivalent metal plating helps resist corrosion and seizing for easier installation and removal, while corrugated ribs help prevent flashover and triple seals help prevent leakage. This resistor spark plug is a solid replacement choice for vehicles and equipment originally equipped with OE nickel alloy plugs.
