About this product
Upgrade your motorcycle's performance with the Denso IU24 Iridium Spark Plug. Engineered for superior ignition and longevity, this spark plug delivers enhanced power and efficiency. Experience the difference of Denso's advanced technology.
Description
The Denso IU24 Iridium Spark Plug is designed for motorcycle enthusiasts and professionals seeking optimal engine performance. Featuring iridium electrodes that are six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this spark plug ensures exceptional durability and reliability. The ultra-fine 0.4mm iridium electrode reduces voltage requirements and significantly improves firing performance. Its 360° laser-welded electrode provides a robust seal that resists wear, even under the most demanding conditions. The ground electrode is designed with a tapered cut and U-groove, creating a large volume area that optimizes flame propagation for a more complete and powerful combustion. This results in improved throttle response, increased fuel efficiency, and reduced emissions. Easy to install with its 16 mm (5/8") hex size, the Denso IU24 is a direct replacement for your stock spark plug, guaranteeing a seamless upgrade.
