Shop parts for a 2018 Husqvarna TE150 Dirt Bike.

Regular cleaning and periodic replacement of the air filter on your 2018 Husqvarna TE150 is essential for engine protection and optimal performance. A well-maintained air filter ensures your bike breathes easily even on the toughest trails, preventing dust, sand, and debris from causing costly engine damage.

What Makes the TE150 Air Filter Special?

  • Premium dual-stage foam: The TE150's air filters, such as those from Twin Air, FLO, and Pro X, feature a bonded two-layer foam design. This dual-stage construction filters out even the smallest dirt particles while permitting maximum airflow for peak engine performance.
  • Perfect fitment: Filters are specifically sized for the TE150 to maximize air circulation and coverage, sealing tightly around the airbox for superior protection.
  • Accessory filter screens available: Consider using additional filter covers or screens for enhanced protection against mud and sand, especially in harsh riding environments.

Cleaning Your TE150 Air Filter

  1. Remove the seat to access the air filter mounted in the airbox.
  2. Take out the air filter and inspect it for rips, gasket wear, or any excessive dirt. Replace if damaged or excessively soiled.
  3. Pre-clean: Lightly tap the filter to remove heavy debris and shake out loose dirt.
  4. Soak – Wash: Use an air filter-specific cleaner or a mild, biodegradable degreaser. Gently massage the foam in the cleaning solution. Avoid wringing or twisting to prevent damage to the foam seams and glue.
  5. Rinse thoroughly with clean water. Repeat if necessary until water runs clear.
  6. Dry: Carefully squeeze out water – do not wring – then allow the filter to air dry completely. Do not use compressed air or direct heat, as this can damage the foam structure.

Oiling – Installing Your Air Filter

  1. Apply high-quality foam air filter oil evenly, making sure all surfaces are sticky (but not saturated). Gently work oil into the foam for full coverage. Excess oil should be squeezed out – never left to drip.
  2. Check the sealing surface of the filter and airbox. Add a thin layer of waterproof grease to the rim of the filter for added seal if desired.
  3. Reinstall the air filter, ensuring it seats securely and is sealed properly in the airbox.
  4. Reattach the seat and double-check your work before riding.

Replacement Recommendations

  • Replace the air filter when it shows signs of tearing, breakdown, or after multiple cleanings have reduced its efficacy. Most riders benefit from keeping a spare on hand for rapid swaps during heavy use or after extremely dusty rides.
  • MotoSport carries recommended filters like Twin Air, FLO, and Pro X, all compatible with the TE150 for dual-stage protection and perfect fitment.

TE150 Owner Notes

  • The 2018 Husqvarna TE150 is engineered for off-road extremes, making air filtration a critical service item. Its high-strung 2-stroke powerplant is sensitive to even small amounts of dust ingestion, so checking your filter before every ride is good practice.
  • Using an additional filter screen or cover is highly recommended for mud or sand-heavy conditions, adding another layer of engine protection.

Routine maintenance of your 2018 Husqvarna TE150 air filter ensures long engine life, sustained horsepower, and trouble-free rides regardless of conditions. Keeping a replacement on hand and adhering to the above process is the best insurance for off-road performance.
