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

The NGK Iridium IX Spark Plugs utilise a 0.6mm laser welded fine iridium tip which ensures high durability and a consistently stable spark along with a tapered ground electrode which minimizes electrical quenching effect. The longer insulator nose prevents fouling, the corrugated ribs on the insulator prevent flashover and a triple gasket seal eliminates combustion gas leakage.
