Transform your Harley Davidson Road Glide Special FLTRXS to how it should have been delivered from the factory with the BoosterPlug fuel injection upgrade.
With the BoosterPlug you will have a better solution than the complicated and expensive Power Commander that is almost impossible to set up correctly.
You don't have to be a trained engineer or a computer programmer to install the BoosterPlug upgrade. Easy and fast plug and play installation.
Release the full potential in your motorcycle:
- Improved and softer throttle response
- Faster acceleration
- Say goodbye to the low speed surge issue
- Takeoff made easy by the stronger idle
- Little to no popping in your aftermarket exhaust
This version of the BoosterPlug upgrade covers all versions of the Harley Davidson Road Glide Special FLTRXS with the 107 or 114 Milwaukee 8 engine (2017 to 2020).
If you have an older Road Glide Special FLTRXS, you can find the BoosterPlug for it in the related products below.
Please note that we can not build a BoosterPlug for the "2021 and newer" model due to new emission regulations. You can see the detailed explanation here
