The NGK Laser Iridium spark plug delivers high ignitability and long life as an OE-equivalent replacement. Its fine iridium center electrode is extremely durable, about six times harder than platinum, while a platinum pad on the ground electrode promotes even wear in distributorless systems. High-grade alumina ceramic and a 98% pure copper core help prevent overheating; trivalent plating aids corrosion resistance.
