VHM Carbon Airbox Intake Boot for YAMAHA YZF 250 2019-2020

The VHM AI020619 airbox intake boot is designed for YAMAHA YZF 250 from 2019 to 2020. The intake boot connects the airbox to the throttle body on a four-stroke engine. The stock rubber boot softens with heat and can lose its shape; a rigid boot keeps its shape and ensures a consistent airflow.

Key features

• Carbon boot: unlike a rubber boot, it doesn't soften or lose its shape with heat.

Fitting tips

1. Remove the seat, the air filter and the stock boot following the manual.
2. Fit the new boot, pushed fully onto the throttle body, and tighten its clamp.
3. Check the seal with the airbox: no dust must be able to get through.
