Trivalent metal Plating provides superior anti-corrosion and anti-seizing properties. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage.

Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Hex size-5/8 inch. Resistor Value-5K Ohm. Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.

Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling.

Upgrade your ride: level up over oem, v-power, g-power, and standard grade plugs with the NGK Iridium IX Spark Plug that provides superior performance and durability.
Enhance performance: the iridium alloy used in the NGK Iridium IX is six times harder and eight times stronger than conventional platinum and can handle temperatures associated with fuel-injected and turbocharged engines. Maximize ignitability: the focused flame kernel allows faster combustion, and the tapered-center ground electrode reduces energy absorption.
