At DMG Motorsports, we present the Hiflofiltro HFA4601 Air Filter — an OE-spec replacement engineered to restore your bike's factory airflow and filtration performance without any guesswork. Built to slot straight into the original air box, this filter is a direct swap for the factory unit on select Yamaha and Moto Guzzi models, meaning no re-jetting, no carburetor tuning, and no modifications required. Hiflofiltro backs this filter with the same Powerflow filtering media used across its range, engineered to keep modern high-performance engines breathing clean while protecting internal components from dirt and debris. Whether you're doing routine maintenance or replacing a worn-out factory filter, the HFA4601 delivers OEM fit and finish at an aftermarket value.
