Recommended for:

The FL-XiED-10's are a cost effective alternative to an aftermarket tuner & dyno runs.  FL-XiED-10's will cool your bike down and make it run better.



  • Touring  2010-2016
  • Softail  2012-2017
  • Dyna  2012-2017
  • V-Rod  2012-2016

Note:  It is recommended that bikes that have full exhaust system upgrades, or those with the catalytic converter removed, use the FL-ViED-10 product.  Fine tuning of the O2 sensor signals may be required to optimize the fuel mixture when the catalytic converter is not in place.


Simple install-comes with instructions.  No tools required, installs in a few minutes.


2014-17 Sportsters use the XL-ViED-14


They work inline with the smaller H-D Delphi heated narrow band 02 sensors and Delphi ECM to richen the fuel mixtures, adding 6% more fuel to the engine in closed loop mode.

There is an indirect richening of the open loop fuel mixtures through the learning mode, or adaptive fuel value action built into your ECM.  This ensures the richer 13.8-12.5:1 AFR's are ALSO adjusted in heavy/full throttle operation.


Kick ass product, bikes running cooler and smoother. -Lyle


"409” ignition wires provide continuous heat protection up to 600-degrees Fahrenheit

Customer Reviews

Easy to Install, Nice Upgrade Review by W9awx
Purchased the enrichment plug and play kit for my stock 2015 Softail Heritage Classic. Very simple install. Total time was about 30 minutes with a bunch of futzing around figuring out where to run the ground wires. Engine sounds smoother getting the little extra fuel it needs. No barking on deceleration now and acceleration is much smoother too. If you do not have plans to move into a stage two, three, or four at some point, this is a no-brainer. (Posted on 10/29/2020)
