The NGK 5545 Iridium IX Spark Plug - DPR9EIX-9 is crafted for high-performance applications, offering a fine wire center electrode that guarantees high durability and a consistently stable spark. The iridium alloy used in the electrode has an extremely high melting point, ideal for today's advanced high-performance engines. It features trivalent metal plating for superior anti-corrosion and anti-seizing properties, along with corrugated ribs to prevent flashover. The pure alumina silicate ceramic insulator provides exceptional strength and efficient heat transfer, while the copper core aids in effective heat removal. Triple seals prevent leakage, ensuring optimal engine performance and longevity.
