Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.
The 0.6mm laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect.
Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage.
Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines.
Trivalent metal plating has superior anti-corrosion and anti-seizing properties.

Heavy-duty nickel center electrode ensures longer life than standard copper plugs.
Copper core provides better heat transfer for resistance to pre-ignition and fouling.
Metal glass fused resistor maximizes interference suppression.
Ribbed insulator design prevents misfire due to current leakage.
Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize.
