There is no generic “scooter air filter.” Airbox shape, engine family, intake location, and service method vary even within one badge. These are named replacement filters with published model or OEM-number applications. Match the exact year, engine, airbox, and part number before ordering. Dry DS elements should not be oiled; foam filters require only the oiling method specified by their manufacturer.

Buying tips
- Match the airbox and OEM number, not only displacement or brand name.
- Dry paper or DS elements are not foam filters and should not be oiled.
- For foam elements, use the maker’s specified cleaning and oiling instructions; excess oil can contaminate the intake.
- A “universal” cone filter is a near-miss, not a replacement unless its dimensions, jetting needs, mounting, and local rules are confirmed.
