Denso Iridium Spark Plug #5317 Vespa ET2 50 1997-2001

Product Details

  • Six times harder than platinum, iridium doesn't melt in temperatures up to 4,000 degrees Fahrenheit
  • Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves
  • 360 degree laser welding of electrode provides a seal that resists wear even in the worst conditions
  • Ground electrode features a tapered cut and u-groove that form a large volume area for the flame's center
