NGK Laser Iridium spark plugs (ILFER7B8EG), sold as a box of four, use a fine-wire iridium center electrode and high-grade alumina ceramic insulator for OE-level durability and consistent spark. The iridium tip offers higher melting point and extended life compared with larger electrodes. Features include a copper core for heat removal, trivalent anti-corrosion plating, triple seals to prevent leakage and a platinum pad on the ground electrode for even wear in distributorless systems.
