Shop parts for a 2017 KTM 150XCW Dirt Bike.

Keeping your 2017 KTM 150XCW in peak riding condition means regular care for the air filter, a mission-critical component designed to protect your engine from dust, debris, and water. The twin-layer foam construction of the filter provides excellent airflow while trapping harmful particles. For this model, KTM recommends checking the filter about every 30 minutes of off-road riding, or more often if you're tackling especially dry, silty, or dusty trails. Neglecting this can starve your engine of air, reduce power, and accelerate wear.

  • Clean absorbent towels

Oiling and Reinstalling the Air Filter

  3. Slide the foam filter back onto the supporting cage, ensuring correct fitment without bunching.
  4. Insert the assembly back into the airbox, matching the notches for proper orientation.
  5. Secure the air filter frame, ensuring a snug, uniform seal all around the intake.
  6. Before replacing the cover and seat, inspect the airbox for debris and clean as required.

Replacing the Air Filter

For the KTM 150XCW, the Twin Air 154116X or equivalent is recommended for best fitment and reliability1.
