Iridium IX DCPR7EIX Spark PlugsNGK Iridium IX DCPR7EIX Spark Plugs for Harley-Davidson Twin Cam 1999-2016, Pair

Iridium plugs for Twin Cam motorcycles

The NGK Iridium IX range uses a very fine iridium centre electrode. NGK says this small diameter lowers the voltage needed to fire the plug. The shell has a plated finish for resistance to corrosion.

Ready to fit from the box

These plugs come pre-gapped, so they are set up for fitting without adjusting the gap first. Supplying them as a pair means you can change both plugs on a twin-cylinder engine at the same time.

What comes in the pack

The pack contains two spark plugs, part number DCPR7EIX. They are listed for Harley-Davidson Twin Cam engines from 1999 to 2016.

How to use

With the engine cool, remove the old plugs and fit the new pre-gapped plugs into the spark plug holes. Tighten them following the engine manual and refit the plug leads.
