Denso IW20 Iridium Spark Plug

Maximize your engine's performance with the Denso IW20 Iridium Spark Plug. Engineered for superior ignition and longevity, this spark plug delivers consistent power and reliability for your motorcycle.

Description

The Denso IW20 Iridium Spark Plug features an iridium electrode that is six times harder than platinum and capable of withstanding extreme temperatures up to 4,000°F. Its ultra-fine 0.4mm iridium electrode significantly reduces voltage requirements, resulting in enhanced firing performance and improved combustion. The 360° laser welding ensures a robust seal, resisting wear even under the most demanding conditions. The ground electrode incorporates a tapered cut and U-groove design, creating an ample area for flame expansion and promoting efficient burning. This resistor-type spark plug has a 14mm thread size, a 19.1mm (3/4") thread reach and a 1.1mm spark gap.
