The NGK Laser Iridium spark plug is a premium OE-replacement offering long service life and consistent ignitability. Iridium-tipped fine wire center electrode delivers superior durability—around six times harder than platinum—while a high-grade alumina ceramic insulator and 98% copper core help dissipate heat and prevent overheating. Triple seals and trivalent plating resist corrosion and seizing, making these plugs a reliable choice for high-tech engines and enthusiasts.
