NGK Laser Iridium spark plugs combine long life with consistent spark performance through a fine iridium-tipped center electrode that resists wear better than platinum. High-grade pure alumina ceramic and a 98% pure copper core help prevent overheating and ensure reliable starts. Many variants include a platinum pad on the ground electrode for even wear in distributorless ignition systems, making them a strong OE-equivalent option for modern engines.
