The NGK Laser Iridium spark plug pairs a fine-wire iridium center electrode with OE-quality construction to deliver durable, consistent ignition and extended service life. Iridium’s extreme melting point and a center electrode six times harder than platinum resist wear, while high-grade alumina ceramic and a 98% copper core aid heat control. Many Laser Iridium plugs also use a platinum pad on the ground electrode for even wear in distributorless systems.
