Description
A properly functioning air filter is critical for maintaining consistent engine performance and fuel efficiency on your XS400. Factory filters deteriorate over time, restricting airflow and reducing throttle response—the Hiflofiltro HFA4402 restores unrestricted intake flow while providing superior filtration for long-term engine protection. This is a direct bolt-on replacement that requires zero modifications to your stock airbox.
