Overview of Denso Iridium Spark Plug - IW16

  • Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves
  • Six times harder than platinum, iridium does not melt in temperatures above 4000 deg. F
  • Ground electrode features a tapered cut and U-groove that forms a large volume area for the flames center
  • 360 deg. laser welding of electrode provides a seal that resists wear even in the worst conditions
  • Replaces NGK #'s: BP5ES, BPR5ES, BP5ES-11, BPR5ES-11 and BPR5EVX-11

Bike runs better

September 26, 2013

I put these in my Vulcan a few years ago and I swear it ran better and was a touch more powerful. Same goes for the FXD, faster, smoother, better. Great plugs!

I would recommend this item to a friend.

Replaced the stock Harley plugs and the bike runs great! They came pre-gapped at .040 so they were ready to go.
