Description
The Denso IW22 Iridium Spark Plug utilizes advanced technology to provide unmatched performance. Featuring an iridium electrode that is six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this 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 creates a robust seal that resists wear, even under the most demanding conditions. The tapered cut and U-groove design of the ground electrode optimize flame propagation, resulting in a more complete and efficient combustion process. Upgrade to Denso Iridium spark plugs and experience improved throttle response, increased power, and reduced emissions.
