Overview of Denso Iridium Spark Plug - IW31

  • Because the iridium electrodes of this plug can be shrunk to only 0.4mm;, voltage requirements decrease while firing performance improves
  • Six times harder than platinum, iridium does not melt even in temperatures above 4,000deg. F
  • Ground electrode features a tapered cut and U-groove that form a large volume area for the flames center
  • 360deg. laser welding of electrode provides a seal that resists wear even in the worst conditions
  • Sold each
