2024-25 YZ250F Airbox upgrade kit w/ Vortex

 2024 YZ250F Airbox upgrade kit w/ Vortex ecu

 

Kit consists of:

Vortex ECU w/ 10 custom Twisted Development Maps

Airbox

*Adaptor for throttle body

The new intake design of the 2024 YZ250F changed the power delivery and removed some bottom end grunt in favor of top end power and overrev. Most people expect the torquey feel of the Yamaha, and this kit returns the YZ250F to having the strong bottom end feel it is known for. The new airbox has a different volume than the stock setup, so combined with our tuning the bike feels much stronger throughout the entire powerband. 

 

*For this kit, the adaptor needs to be pressed onto the throttle body and cannot be installed by hand. If you do not have access to a press or are not comfortable pressing on your throttle body, you can send your throttle body to us to install the adaptor. Call us with any questions or to confirm availability of the kit prior to sending in parts*

 

THIS AIRBOX WILL NOT FUNCTION PROPERLY WITHOUT THE ADAPTER AND CORRECT MAPPING.
