The NGK Laser Iridium spark plug, in a box of 4, is engineered for long life and consistent spark delivery. An iridium-tipped fine wire center electrode offers exceptional hardness and durability, while the copper core and pure alumina ceramic insulator aid heat control and dielectric reliability. Many Laser Iridium plugs also use a platinum pad on the ground electrode to promote even wear in distributorless ignition systems.
