Air Filter Cleaning & Replacement Guide for 2015 Husqvarna TE125
Keeping the air filter of your 2015 Husqvarna TE125 in top condition is one of the most effective ways to ensure long engine life and consistent performance. The TE125 features a single-cylinder, two-stroke engine that relies on clean air for reliable operation. Extreme dust, mud, and water splashes encountered on trails make frequent air filter maintenance especially important for this model.
Why Air Filter Maintenance Matters for the TE125
- Two-stroke engines like the TE125 are sensitive to airflow restrictions and dust–even minor neglect can lead to loss of power, premature engine wear, and hard starting.
- The 2015 TE125 uses a polyurethane foam air filter specifically designed for high filtration and airflow in off-road conditions.
- Unique to this model, the air filter can be serviced without tools by removing the left side airbox cover, making cleaning quick and seamless.
- Genuine filters feature multiple layers of foam to optimize filtration–always inspect the integrity and fit of both the foam element and the filter cage.
How to Clean the Air Filter
-
Remove the Airbox Cover:
Open the left side panel. Locate the tab and gently pull the airbox cover off. The filter is held in place on a cage–squeeze the filter and pull straight back. -
Check for Damage:
Inspect the foam element for rips, breaks, or glued seams coming apart. Any damaged filter must be replaced immediately. -
Remove Gross Debris:
Tap the filter gently to dislodge sand and debris. Do not bang or wring, as this can tear the foam. -
Wash the Filter:
Submerge in a bucket of warm water with a dirt bike-specific air filter cleaner or mild detergent. Work the solution through the foam by squeezing (never twisting or wringing). -
Rinse Thoroughly:
Rinse in clean water several times until no soap or dirt remains.
Allow the filter to air dry completely–avoid heat sources, which can deform the foam. -
Oil the Filter:
Once dry, apply high-quality foam filter oil evenly, massaging to work the oil into all pores. Avoid leaving dry spots. Keep oil off the inside of the filter cage for best engine protection. -
Check the Sealing Surface:
Lightly grease the filter's mounting lip for a positive seal against the airbox and prevent fine dust bypass. -
Reinstall:
Position the filter back onto the cage and press it firmly in place. Double-check seat and cover alignment before securing the airbox cover.
How Often Should You Service the Filter?
- Inspect and clean after every ride in dusty or wet conditions.
- For standard trail use, service the air filter every 2-3 rides.
- Replace with a new filter if you notice visible holes, weakening seams, or thick grime that doesn't wash out.

- 2015 TE125 air filters are interchangeable within the 2011-2017 KTM and Husqvarna models, providing a wide selection of compatible replacements and upgrades.
- Always ensure the filter cage and mounting bushings are clean–dirt in these areas can cause sealing issues and engine damage.
- When reinstalling, use the recommended air filter foam thickness and shape for the best performance.
- Check the airbox for water; the TE125's electric start and electronics are vulnerable if wet debris is pulled through a damaged filter.
