NGK SPARK PLUG CR7HSA NG4549 NG4549
NGK SPARK PLUG CR7HSA NG4549. This spark plug features a wide heat range with a copper wire that dissipates heat quickly for effective electrode and insulator tip cooling. It offers improved performance through a raised pre-ignition rating and a long nose insulator for stable ignition. Designed for longevity and reliability, it meets the requirements of high-performance engines. Trivalent metal plating provides superior anti-corrosion and anti-seizing properties, while corrugated ribs on the insulator prevent flashover. The pure alumina silicate ceramic insulator ensures better heat transfer and increased strength. Triple seals prevent leakage for consistent performance. Specifications include a heat range of 7, 10mm thread size, resistor type, sold as a single unit, and a weight of 0.06 lbs. Alternate/OEM part numbers are 4549 and CR7HSA.
