NGK CR7HIX 7544 spark plug is a performance-grade Iridium IX plug designed for enhanced durability and stable ignition in high-tech, high-performance engines. It features a copper core, an iridium fine-wire electrode, and advanced coatings to resist corrosion and flashover. The fine-wire iridium center electrode provides a consistent spark and high durability, with an iridium alloy electrode that has a high melting point suitable for modern high-efficiency engines. Trivalent metal plating offers enhanced anti-corrosion and anti-seizing characteristics. Corrugated ribs on the insulator prevent flashover, while the pure alumina silicate ceramic insulator provides superior strength and heat transfer. A copper core ensures effective heat dissipation, and triple seals prevent leakage. This is a resistor type plug to suppress interference. Specifications include a 5/8 inch (16mm) hex size, 10mm thread diameter, 1/2 inch (12.7mm) thread reach, projected insulator type, approximately 5kO resistor value, heat range 7, and a 0.028in (0.7mm) gap size. The center electrode tip is fine iridium, 0.6mm diameter. The ground electrode is single tapered cut nickel, and the seat type is gasket.
