The NGK Laser Iridium High Ignitability spark plug pairs extended tip durability with improved spark performance for demanding engines. An iridium-tipped center electrode offers superior hardness and longevity while a fine-wire center electrode and platinum or raised platinum pad on the ground electrode promote even wear and stable sparks in distributorless systems. High-grade alumina ceramic and a 98% copper core resist overheating; trivalent plating and triple seals protect against corrosion and leakage. Supplied in a box of 4.
