The NGK Laser Iridium spark plug provides OE-level longevity and stable ignition for modern engines. Its iridium fine-wire center electrode offers durability well beyond platinum, supported by a high-grade alumina ceramic insulator and a 98% copper core to control heat. Most Laser Iridium plugs use a platinum ground pad, plus trivalent metal plating and triple seals to prevent corrosion and combustion leakage.
