Release the full potential in your motorcycle:
- Improved and softer throttle response
- Improved acceleration
- Say goodbye to the low speed surge problem

- Little to no popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the Harley Davidson Tri Glide Ultra Classic FLHTCUTG with the Milwaukee 8 engine (2017 to 2020).
