NGK Iridium Spark Plugs feature a laser welded Iridium center electrode tip which ensures high durability and a greater spark while the platinum disc welded to the backside of the ground electrode provides a longer life. The longer insulator nose prevents fouling, the corrugated ribs on the insulator prevents flashover and the triple gasket seal eliminates combustion gas leakage.
