The NGK Laser Iridium Long Life spark plug combines a fine iridium center electrode with a raised platinum ground tip to deliver extended durability and consistent spark for OE-equivalent replacement. High-grade alumina ceramic and a 98% copper core aid heat control and reliable starting. Trivalent plating and triple seals limit corrosion and leakage; recommended for vehicles originally equipped with OE SPE-type iridium plugs.
