Fuel Injection improvements on the Harley Davidson Road Glide Ultra FLTRU are usually expensive and complicated. The BoosterPlug is a better and proven alternative.
No need to spend a small fortune on complicated devices like the Power Commander + endless Dyno hours, to make your bike run like it should have from the factory.
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 - no more stalling problems
- Reduced popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the Harley Davidson Road Glide Ultra FLTRU with the Milwaukee 8 engine (2017 and newer).
