Cleaning the Foam Air Filter: Step-by-Step
- Remove the seat and access panel to reach the air filter box.
- Carefully detach the air filter from its frame to avoid spilling dirt into the intake tract.
- Inspect the filter for damage; cracks or crumbling foam means it must be replaced (KTM OEM Air Filter: Part 54606015000 fits this model)–5.
- Wash the filter in a dedicated foam air filter cleaner or mild, biodegradable soap. Gently squeeze but do not wring or twist the foam layer.
- Rinse repeatedly until water runs clear.
- Let the filter air dry completely in a clean, dust-free environmentnever use compressed air or heat sources.
- Once dry, apply a generous amount of foam filter oil. Massage the oil throughout the layers. Carefully blot excess oil, but ensure all pores are saturated for maximum dirt-trapping ability.
- Install the filter onto its mounting frame, making sure the sealing edge is flush and seats tightly against the airbox. Grease the airbox lip if riding in extremely dusty conditions.
- Reinstall the filter, access panel, and seat securely.
How Often Should You Clean or Replace?
- Clean after every ride in severe dust or sand, or at minimum every 2-3 rides on cleaner trails.
