Whether you're an experienced racer or a weekend trailblazer, efficient air filter care is critical for maximizing the performance and longevity of your KTM’s powerful mid-size four-stroke engine.
Key Features of the 2025 KTM 350XCF Air Filter System
- Twin Air Filter: Features a fail-proof cage and mounting system for safe, accurate installation.
- Tool-Free Access: Remove the left side panel to access the air filter – no tools required.
- Optimized Airbox: Precisely positioned ducts prevent air deformation and shield the filter from debris.
- Water Protection Option: For extremely wet conditions, KTM offers a washable air filter water protection cover to add an extra safeguard against moisture ingress. This is especially recommended if you ride in muddy or wet environments.
How to Access the Air Filter
- Ensure the bike is clean, cool, and on a stable stand.
- On the left side of the bike, locate the airbox cover.
- Release the latches or fasteners (no tools needed) and carefully remove the side panel.
- The air filter is now visible – mounted in a secure cage system for consistent fit and protection.
Cleaning the Air Filter
- Gently remove the air filter and filter cage as a single unit.
- Carefully separate the foam filter from the cage.
- Inspect the filter for excessive wear or damage. Replace if necessary.
- Clean the filter using a proper foam air filter cleaner – never use gasoline or compressed air, as these can damage the foam and compromise performance.
- Once cleaned, allow the filter to dry completely, then re-oil it with a high-quality foam air filter oil. Work in the oil evenly, ensuring full coverage and squeezing out excess (do not wring or twist).
- Reinstall the filter onto the cage, checking for a secure and gap-free fit.
- Carefully reinstall the filter and cage into the airbox, confirming it clicks or seats fully. Misalignment can allow unfiltered air into the engine.
- Reattach the airbox cover and secure any latches.
Replacement Recommendations
- Inspect & clean your filter after every dusty or muddy ride, especially in extreme conditions.
- Replace the air filter at least every 15–20 hours of use or sooner if showing signs of deterioration (tears, compressed foam, permanent discoloration).
- For wet environments, consider adding KTM's air filter water protection cover for additional defense.
