NGK Laser Iridium spark plugs (box of 4, ILFER7A8EG) pair an iridium-tipped fine-wire center electrode with a high-grade alumina ceramic insulator for durability and consistent spark. Iridium provides superior electrode hardness and a high melting point, while copper cores assist heat removal. These plugs are OE-style replacements aimed at offering long life and reliable ignition in modern engines requiring fine-wire iridium plugs.
