NGK Laser Iridium spark plugs deliver a blend of longevity and reliable ignition for OE-replacement use. The iridium-tipped center electrode resists wear and sustains a consistent spark, while the alumina ceramic insulator and copper core help manage temperatures and ensure dependable starts. Many Laser Iridium variants also use a platinum pad on the ground electrode for even wear in distributorless ignition systems.
