Air Filter Cleaning – Replacement Guide for 2013 KTM Freeride350

Shop parts for a 2013 KTM Freeride350 Dirt Bike.

The 2013 KTM Freeride350 features a unique dual-layer foam air filter specifically designed for versatile off-road environments. Proper cleaning and timely replacement of the air filter are critical to preserving engine power, throttle response, and the extended lifespan of your dirt bike.

Why Air Filter Maintenance Is So Important for the Freeride350

  • Dual-layer foam construction: Designed for optimal dust and debris capture on varied terrain, this filter is more susceptible to performance loss if neglected due to the bike's open, easily accessed airbox design.
  • Mature foam filters degrade when over-oiled or insufficiently cleaned, leading to premature engine wear.
  • Cleaning and proper re-oiling restore filter efficiency and ensure consistent airflow required for KTM's fuel-injected engine management.

How Often to Service Your Air Filter

  • Inspect before and after every ride in dusty or wet conditions.
  • Clean after every 3–5 rides in mild conditions, or more frequently with heavy dust or water crossings.
  • Replace the filter annually, or sooner if it shows tears, permanent staining, or loss of foam elasticity.

Required Tools – Supplies

  • Gloves
  • Air filter cleaner/degreaser (or gentle dish soap for DIY approach)
  • Air filter oil suitable for KTM dual-layer foam
  • Clean water
  • Soft bristle brush (optional)
  • Replacement air filter for KTM Freeride350 (OEM part number 72006015000)

Step-by-Step: Air Filter Removal

  1. Remove the seat to expose the airbox.
  2. Take off the airbox upper part as needed for improved working space.
  3. Detach the air filter carrier by unclipping it.
  4. Pull the filter and carrier out as a single unit – avoid twisting or bending the frame.
  5. Carefully remove the filter from its carrier frame.

How to Clean the Air Filter

  1. Tap the filter gently to shake off loose dirt.
  2. Apply air filter degreaser or mild soap – massage gently for even dirt removal. NEVER use gasoline or harsh solvents as these damage foam and glue layers.
  3. Rinse with cool water from the clean side out to drive contaminants away from the engine-facing surface.
  4. Squeeze (do not wring) to remove water. Set aside to fully air dry away from direct sunlight and heat since these degrade foam over time.

Oiling and Reinstallation

  1. Once dry, apply a small amount of foam filter oil. Work it through the filter for complete coverage, focusing on seams and folds.
  2. Squeeze out excess oil – filter should be damp but not dripping. Too much oil restricts airflow and increases dirt attraction.
  3. Install the filter onto the support frame. Check that the filter's sealing rim sits flush on the airbox edge for a tight seal – the Freeride350's airbox is exposed, so even minor gaps allow dirt ingress.
  4. Reverse the removal steps: insert carrier with filter, secure airbox upper part, and reinstall the seat.

When – How to Replace the Air Filter

  • Replace if foam is torn, deteriorated, or cannot be fully cleaned due to staining or old oil saturation.
  • For the 2013 KTM Freeride350, the OEM filter (part number 72006015000) is recommended for best fit and longevity.

Model-Specific Tips for the 2013 Freeride350

  • The air filter is especially accessible but also more exposed compared to other KTM models. This increases maintenance necessity, especially in muddy or sandy conditions.
  • The airbox design makes it susceptible to water or debris if the seat is not fully secured after maintenance—double-check seat fit every time.
  • Do not substitute single-layer filters, as KTM's dual-layer design is critical for this model's air intake requirements and engine protection.
