Twin Air 160742 Powerflow Throttle Body Kit for Husqvarna FC 350/450 14-15/KTM 350 XC-F/450 SX-F/XC-F 13-15

Get faster, smoother throttle response where you need it most. Installed in your throttle body’s Venturi tube, the precision-engineered sleeve reduces the diameter and accelerates the velocity of your air-fuel mix.

Add the thinner butterfly valve and less obstructive shaft, and you’ve got faster, more even throttle response through low- and mid-range.

For better top-end throttle response (90-100% open throttle position), use the kit’s larger butterfly valve without the sleeve.
