The NGK Laser Iridium spark plug blends long life with reliable OE-equivalent performance. A fine iridium-tipped center electrode provides extreme durability and consistent spark, while high-grade alumina ceramic and a copper core help prevent overheating and ensure reliable starts. Many Laser Iridium plugs include a ground-electrode platinum pad for even wear in distributorless systems, making them a durable replacement for modern engines.
