The NGK Iridium IX spark plugs are engineered for high-performance engines, delivering outstanding acceleration, improved fuel efficiency, and exceptional durability. Designed specifically for enthusiasts seeking reliable ignition and enhanced engine response, these plugs feature a tapered cut ground electrode that promotes better starting, smoother idling, and more responsive throttle control. The Iridium fine wire center electrode offers six times the hardness of platinum, ensuring long-lasting performance under demanding conditions. With an extremely high melting point thanks to the iridium alloy construction, these plugs are well-suited for modern engines that require robust, high-temperature components. Ideal for a variety of ATVs and motorcycles, they provide dependable ignition for models such as Honda XR80R, Honda SL70, and others in the same class. Upgrading to NGK Ruthenium HX plugs can further improve performance for those seeking even greater efficiency and power.
