The NGK 91924 Laser Iridium Spark Plug (ILZNAR8A7G) is engineered to meet the demands of high-performance engines. With its fine wire iridium tipped center electrode, it ensures exceptional durability and a consistently stable spark. The iridium alloy, with its extremely high melting point, is ideal for modern high-tech engines. The spark plug features trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for enhanced strength and heat transfer. A copper core aids in effective heat removal, and triple seals are incorporated to prevent leakage. This spark plug provides reliable performance, contributing to improved engine efficiency and longevity.
