NGK Laser Iridium spark plugs (box of 4, SILZKFR8H7S) use a fine iridium center electrode for high ignitability and long tip life, offering OE-grade replacement performance. Iridium alloy provides superior melting-point durability compared with platinum, while a pure alumina ceramic insulator and a 98% pure copper core aid heat control and reliable starts. Raised platinum or fine-wire ground electrodes promote even wear in distributorless ignition systems.
