The new Twin Air intake funnel increases throttle response and mid to top-end power on the latest 2021-2023 Honda CRF450R and the 2022-2023 CRF250R models.
It’s easy to install with no modification to any OEM part. Once installed, the throttle feels lighter under acceleration and pulls each gear longer.
For maximum performance benefits, use the PowerTune together with the Twin Air PowerFlow Kit (part number 150231C).

This is a budget solution to the VHM Carbon fibre version.
