Riding the 2019 Husqvarna TE150 means navigating a variety of conditionsfrom dusty trails to muddy single-track. To keep your two-stroke engine performing at its best, routine air filter maintenance is essential. The TE150 uses a high-quality dual-layer foam filter engineered for off-road durability, making proper cleaning & replacement critical for engine longevity.

How to Clean the Air Filter

  • Remove the seat & air filter cover: Access the filter by first disengaging the seat latch and removing the seat. The TE150 utilizes a quick-release seat for fast access.
  • Extract the air filter: Gently pull out the filter and inspect its foam integrity. Typical for this model, the filter is a dual-layer foam design, optimized for catching grime, sand & fine dust particles .
  • Pre-clean: Carefully tap the filter to remove loose debris. Avoid forceful squeezing that could tear the foam.
  • Soak with cleaner: Use a dedicated foam filter cleaner or mild soap solution. Massage thoroughly to release trapped particulates.
  • Rinse & dry: Rinse with cool water, then press out excess (do not wring) and air-dry completely before re-oiling.
  • Apply air filter oil: Use air filter-specific oil, ensuring full coverage but no pooling. The TE150 filter is designed to work best when evenly oiled for dust sealing & optimal airflow.
  • Inspect airbox: Wipe away any residual dust or grit from inside the airbox and sealing surfaces. Check for gasket wear or damage.
  • Reinstall the filter: Press the filter firmly into its seatthe TE150 features a greaseless sealing ring for maximum contact, acting as a breathable gasket.

When to Replace the Air Filter

  • Replace if foam is torn, brittle, or permanently stained. The TE150's OEM filter is engineered to withstand repeated cleanings, but degradation happens over time.
  • Dual-layer foam offers robust filtration; if layers separate or adhesive not holding, replace immediately to avoid engine contamination.
  • Use recommended replacements like OEM or high-grade performance filters with a 45/65 PPI (pores per inch) dual-layer for best protection.
