NGK Laser Iridium spark plugs (box of 4, ILNFR9B7G) use an iridium-tipped fine-wire center electrode for durability and a stable spark, tuned for OE applications. The plugs feature a high-grade alumina ceramic insulator and a copper core to aid heat transfer, with trivalent metal plating for corrosion resistance. They’re recommended where OE fine-wire iridium plugs are specified.
