Improving the fuel injection performance on your DUCATI Monster 821 is easy and efficient with the proven BoosterPlug tuning solution.
No need to spend a small fortune on complicated devices like the Power Commander + auxiliary parts + 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 tuning choice to optimize the fuel Injection on your motorcycle:
- Soft and smooth throttle response
- Harder acceleration.
- Eliminate the low speed surge issue
- Reduced popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the DUCATI Monster 821 from 2017 and newer.
If you have an older Monster 821 model, you can find the BoosterPlug for it in the related products below.
Note: The Ducati Monster 821 series is using the same temperature sensor for the fuel injection calculations as for the temperature readout in the dashboard. (Most other brands have seperate sensors).
This means that your dashboard display will show 20°C / 35°F lower than actual ambient temperature when you install the BoosterPlug, and you may get an ice warning in the dashboard too.
There's no way around this, and it's probably not an issue for most people, but we want you to be informed about it - and it's an easy way to see that the BoosterPlug is working as intended :-)
