The NGK Laser Iridium spark plug combines long life and stable ignition using an iridium-tipped fine wire center electrode and often a platinum pad on the ground electrode for even wear in distributorless systems. High-grade alumina ceramic and a 98% copper core assist heat control and reliable starts. Corrosion-resistant plating and triple seals reduce seizure and leakage, making these plugs a durable OE-style option.
