The NGK Laser Iridium spark plug is an OE-grade iridium replacement that balances long life with high ignitability for modern engines. Its fine-wire iridium center electrode and often-present platinum pad on the ground electrode deliver consistent spark and even wear under distributorless ignition systems. NGK's alumina ceramic insulator, 98% copper core and corrosion-resistant plating aid heat removal and prevent overheating while triple seals help stop leakage for dependable starts.
