Shop Car Stars Iridium EX Spark Plugs

Designed for performance enthusiasts, the Iridium EX spark plugs offer superior ignitability, improved throttle response, and excellent fouling resistance. The laser-welded 0.6mm iridium tip ensures high durability and a stable spark, while the tapered ground electrode reduces electrical cooling. A longer insulator nose prevents contamination, and corrugated ribs prevent flashover. The triple gasket seal prevents gas leakage. The iridium alloy's high melting point provides durability against thermal and electrical corrosion, ideal for high-performance engines. Trivalent Metallic Coating offers superior anti-corrosion and anti-friction properties.
