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. 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 covers all versions of the Harley Davidson Road Glide Special FLTRXS with the 107 or 114 Milwaukee 8 engine (2017 and newer).
