NGK Laser Iridium spark plug pairs long life with high ignitability for demanding engines. The iridium-tipped fine wire center electrode is far harder than platinum and delivers a consistently stable spark, while a platinum pad on the ground electrode aids even wear in distributorless systems. High-grade alumina ceramic and a copper core control heat for reliable starts and extended service intervals.
