NGK Laser Iridium spark plugs (box of 4, SILZKR8E8G) are engineered for high ignitability and longevity in OE applications. The iridium-tipped center electrode offers a hardness advantage over platinum and the fine-wire design promotes a stable spark. High-grade alumina ceramic and a 98% pure copper core aid heat control, while design features like raised platinum pads on the ground electrode support even wear in distributorless ignition systems.
