Description
The Denso IW24 Iridium Spark Plug utilizes advanced technology to provide exceptional performance and longevity. Its iridium electrode, six times harder than platinum, can withstand temperatures up to 4,000°F, guaranteeing reliable operation even under extreme conditions. The ultra-fine 0.4mm iridium electrode reduces voltage requirements while significantly improving firing performance. The 360° laser welding ensures a robust seal that resists wear and tear. Furthermore, the tapered cut and U-groove design of the ground electrode create a large volume area that optimizes flame propagation, leading to enhanced combustion efficiency and increased horsepower. Upgrade to Denso Iridium spark plugs for improved engine starts, smoother idling, and enhanced throttle response.
