NGK SPARK PLUG CR7E 4578
NGK Spark Plug CR7E 4578. Features a wide heat range with a copper core that dissipates heat more quickly than iron cores, improving engine performance and providing efficient cooling for the electrode and insulator tip. Offers a raised pre-ignition rating with high conduction copper and a long nose insulator for reliability. Designed for longer life and optimum performance with trivalent metal plating for superior anti-corrosion and anti-seizing properties. Corrugated ribs prevent flashover for consistent ignition, and pure alumina silicate ceramic insulator provides better heat transfer and strength. Triple seals prevent leakage. Specifications include a heat range of 7, 10mm thread size, resistor type, and it is sold individually. Weighs 0.06 lbs. Alternate/OEM part numbers are 4578 and CR7E. Part No. 37-CR7E.
