Laser Iridium™ Spark Plug by NGK Spark Plugs®. Electrode Tip Material: Iridium. Spark Plug Gap: Pre-gapped. Often specified as original equipment, NGK Spark Plugs Laser Iridium spark plugs are the best combination of performance and longevity. Iridium tip is six (6) times harder than platinum providing the strongest ignitability and the longest life possible. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in DIS ignition systems. OE engineered for specific vehicle applications.
