NGK Laser Iridium spark plug set (box of 4) offers OE-quality ignitability and longevity using iridium fine-wire center electrodes and high-grade alumina ceramic. The iridium tip resists wear while a 98% copper core aids heat dissipation to keep plugs operating reliably. Many Laser Iridium plugs also include a platinum pad on the ground electrode for even wear in distributorless ignition systems and consistent spark performance.
