Designed for faster starts and quicker accelerationBetter fuel economy and lower emissionsOE approved designLaser welded iridium center electrode tipPlatinum disc welded to backside of ground electrodeIdeal for applications with DIS (Distributorless Ignition System) “waste spark” ignition systems that require double precious metal spark plugsManufactured using triple-gasket sealing process to prevent leakage through the shellAlumina silicate insulator for strength and optimal heat transferCold-rolled threads for easier removal and installationCorrugated ribs eliminate misfire causing “flashover”Trivalent metal platingLast 80 to 100 thousand miles 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.
