The NGK Laser Iridium spark plug delivers a balance of longevity and consistent ignition using an iridium fine-wire center electrode, high-grade alumina ceramic and a copper core to prevent overheating. Many models include a platinum pad on the ground electrode for even wear in distributorless ignition systems. The fine-wire design supports reliable starts, stable idle and enhanced durability for modern engines.
