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, we need you to send your throttle body to us so we can install the special TD adapter. 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.
