NGK Laser Iridium spark plug (ILTR7N10) is a fine-wire iridium-tipped plug engineered for OE-style applications that need long life and a stable spark. The iridium center electrode offers exceptional hardness and high melting point, while NGK's pure alumina insulator and copper core aid heat control and consistent starts. Many Laser Iridium plugs include a platinum pad on the ground electrode for even wear in distributorless systems.
