The NGK Laser Iridium spark plug is an OE-grade iridium-tipped replacement that balances longevity and reliable ignitability for modern engines. A fine-wire iridium center electrode and a platinum pad on the ground electrode deliver consistent spark and even wear. NGK's high-grade alumina ceramic insulator and 98% copper core aid heat removal and prevent overheating; trivalent plating and triple seals help resist corrosion and leakage for durable service.
