The NGK Laser Iridium High Ignitability spark plug pairs longevity with improved spark performance for OE applications. A durable iridium tip and high‑grade alumina ceramic with a copper core resist overheating and provide reliable starting. Raised platinum pads or fine wire tips on ground electrodes ensure even wear in distributorless systems. Engineered for modern engines where high ignitability and consistent spark are priorities.
