The NGK Laser Iridium spark plug pairs an iridium-tipped fine-wire center electrode with high-grade alumina ceramic and a 98% pure copper core to deliver long life and consistent ignition. Many Laser Iridium variants include a platinum pad on the ground electrode for even wear in distributorless systems. The design is intended for drivers seeking durable, stable spark performance and reliable starts across modern engine conditions.
