The BoosterPlug is the easiest and most efficient way to upgrade the fuel injection on your Harley Davidson Freewheeler FLRT .
The BoosterPlug is the best way to sort out the fuel injection on your bike - without the high cost and the complicated programming of a Power Commander.
The BoosterPlug is installed in less than 10 minutes. It plugs directly into your bikes wire harness using original connectors – no cutting or splicing.
The smarter choice to optimize the fuel Injection on your motorcycle:
- Fix the snatchy throttle response problem
- Harder acceleration
- Eliminate the low speed surge problem
- Stronger idle and less tendency to stall
- Aftermarket exhaust backfire reduced or eliminated
This version of the BoosterPlug covers all versions of the Harley Davidson Freewheeler FLRT with the Milwaukee 8 engine (2017 to 2020).
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
