Description
The Denso IU22 Iridium Spark Plug is designed for enthusiasts and professionals seeking optimal engine performance and reliability. Featuring an iridium electrode that's six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this spark plug ensures durability and consistent performance under extreme conditions. The ultra-fine 0.4mm iridium electrode reduces voltage requirements, leading to improved firing performance and quicker starts. Denso's 360° laser welding creates a robust seal, enhancing resistance to wear and tear. The ground electrode's tapered cut and U-groove design create a large volume area for the flame's center, promoting efficient combustion and increased power. With a 10 mm thread size and 19.1 mm (3/4") thread reach, the IU22 spark plug offers broad compatibility.
