Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high performance engines. The 06 millimeter laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect.




Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response.

Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.
