NGK Laser Iridium spark plugs are OE-style iridium-tipped plugs supplied here as a box of four (ILTR6R8G). They combine a fine iridium center electrode, high-grade alumina ceramic insulator and a copper core to aid heat removal for reliable starts and longevity. Many Laser Iridium plugs include a platinum pad on the ground electrode and triple seals to prevent leakage for distributorless ignition systems.
