BoosterPlug KTM Duke 390 (2017 -2020)

Fuel Injection improvements on the KTM Duke 390 are usually expensive and complicated. The BoosterPlug is a better and proven aftermarket alternative to solve the common problems without the need for a load of additional parts.

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 or similar aftermarket parts.

We designed the BoosterPlug to be easy and fast to install, so it comes with the correct connectors so you can install it on your own without problems.

A true plug and play solution that will make your bike so much better:

- Improved and softer throttle response
- Quicker acceleration
- No more low speed surging
- Stronger idle
- no more stalling problems
- Aftermarket exhaust backfire reduced or eliminated

This version of the BoosterPlug covers all versions of the KTM Duke 390 from 2017 to 2020.
If you have an older Duke 390 model, 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.
