- Gently tap to remove loose dirt. For thorough cleaning:
- Use an air filter cleaner or mild, non-petroleum detergent in warm water.

- Clean the airbox and filter sealing surface with a lint-free cloth.
- Reinstall the filter onto the cage, ensuring proper alignment of the filter lip on the airbox sealing ring.
