Description
V-Power Spark Plug UR4 by Ngk Spark Plugs | Engine Systems at West Marine. V-Power Spark Plugs are designed to improve ignitability and reduce quenching for better engine performance. V-Power spark plugs are designed for improved ignition of your engines fuel/air mixture with a V-groove cut in the center electrode parallel to the ground electrode. This directs the spark to the edge of the center electrode, which exposes it to more of the air/fuel mixture. The design also reduces quenching for better ignition performance. Quenching is where the electrodes drain energy from the flame core. In severe cases, this can extinguish the flame core and cause ignition failure. V-Power Spark Plugs include a resistor which reduces Radio Frequency Interference (RFI) or electrical noise that can cause interference with the operation of radios, electronic components, fuel injections systems, depth finders and other sensitive electronic equipment. Key Features Trivalent metal plating provides superior anti-corrosion and anti-seizing properties Corrugated ribs prevent flashover Pure alumina silicate ceramic insulator provides superior strength and better heat transfer Copper core aids in heat removal Triple seal prevents leakage Specifications Resistor: Yes Electrode Material: Nickel alloy Core Material: Copper Plug Selection To ensure optimum performance please consult your owner's manual to determine the correct spark plug for your engine.
