The air filter in your 2018 Husqvarna TC250 is critical to the performance and longevity of your dirt bike.

Why Regular Service is Critical
- Performance: Clean air filters allow proper airflow, supporting maximum horsepower and acceleration.–4
- Protection: The two-layer foam traps large and small particles, preventing damage to the cylinder, piston, and rings.–5
- Durability: Quality foam and adhesives are designed to withstand repeated cleanings without deteriorating.–1
Step-by-Step Air Filter Cleaning
- Remove the seat: Release the seat latch and lift off to access the airbox.
- Take out the filter: Unclip the air filter cage and pull the filter assembly from the airbox gently. Note how it is positioned for reinstallation.
- Inspect the filter: Examine the foam for tears, holes, or degrading. Replace immediately if any damage is found.
- Clean the filter: Rinse the filter in a dedicated cleaning solution or mild, non-flammable solvent. Gently squeeze but do not wring the foam to preserve shape and integrity.
- Dry thoroughly: Allow the filter to air dry completely. Never use heat sources which may deform the foam.
- Re-oil the filter: Apply high-quality foam air filter oil evenly, working oil into all surfaces until uniformly coated but not dripping.
- Reinstall: Mount the filter back onto its cage, ensuring a proper seal. Insert assembly and secure the airbox and seat.
