Ngk V-Power Plugs 2238

The NGK TR5 is a V-Power spark plug designed for economical performance. It features NGK's V-Groove technology, which enhances ignitability, lowers ignition system voltage requirements, and provides strong anti-fouling characteristics. These characteristics contribute to improved fuel mileage and acceleration. The plugs are constructed with a pure alumina silicate ceramic insulator for strength and heat transfer, a copper core for heat removal, and trivalent metal plating for anti-corrosion and anti-seizing properties. They are also designed with corrugated ribs to prevent flashover and triple seals to prevent leakage. The TR5 has a 14mm thread size, a 1.25mm thread pitch, a tapered seat, and a 0.708-inch reach. Its electrode tip is made of nickel alloy, and the center electrode is projected. This is a single-ground strap, resistor spark plug with a manufacturer heat range of 5.
