Fuel Injection mods on the Harley Davidson Road King Classic FLHRC are usually expensive and complicated. The BoosterPlug is a better and proven alternative.

Did you think the complicated Power Commander was the only way to sort out the fuel injection on your bike ? The BoosterPlug mod will offer the better solution at a fraction of the cost.

No complicated mechanical work or programming is required when installing the BoosterPlug. You simply plug it in using the original connectors and you are done.

A true plug and play modification that will make your bike so much better:
- Fix the snatchy throttle response problem
- Stronger acceleration
- No more low speed surging
- Stronger idle
- no more stalling problems
- Minimize the backfire in your aftermarket exhaust

This version of the BoosterPlug covers all versions of the Harley Davidson Road King Classic FLHRC with the Milwaukee 8 engine (2017 - 2020).
If you have an older Road King Classic, 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.
