The 2017 Husqvarna FX450 is a high-performance off-road machine that demands consistent air filter maintenance for optimum power and engine longevity. Keeping your air filter clean and serviced is essential when riding, especially in dusty or sandy environments common for this model's typical use.

Understanding Your FX450 Air Filter System
- Foam Air Filter: The FX450 uses a high-flow, reusable foam filter, which excels at trapping dust and debris when oiled properly.
- Quick Release Airbox Cover: No tools are needed, making routine checks fast and hassle-free.
- Integrated Cage: The filter mounts to a rigid cage with tabs that secure it firmly in place, ensuring an airtight seal.
Cleaning the Air Filter
- Remove the seat and unclip the airbox cover to access the filter cage.
- Carefully detach the filter from the cage tabs, avoiding unnecessary stretching.
- Gently brush or tap off surface dust before removing to prevent dirt from falling into the air intake.
- Soak the filter in a purpose-made air filter cleaner, working it by handavoid wringing or twisting, which can damage the foam and reduce its lifespan – treat the filter gently.
- Rinse in warm water until the cleaner and dirt are fully removed. Repeat if necessary for heavy buildup.
- Let the filter dry completely in a cool, shaded areadirect sun can deteriorate foam quickly.
Oiling and Reinstalling
- Once dry, fully saturate the filter with high-quality air filter oil. Use a biodegradable or regular oil based on your preference, and match cleaner and oil types if possible for best results.
- Work the oil through evenly, ensuring every cell is coated. Gently squeeze out excess oildo not wring.
- Wipe away surplus oil with a clean towel or cloth.
- Apply a light bead of waterproof grease to the airbox sealing rim and the filter's sealing edge to improve dirt protection and ensure a perfect seal.
- Reinstall the filter carefully to the cage, making sure the tabs are fully seated and the seal is flush.
- Double-check that no cleaning cloths or foreign objects remain in the intake tract before closing the airbox and replacing the seat.
Replacement Guide
- Replacement Interval: Replace the air filter if the foam is torn, excessively worn, or after several cleaning cycles.
- Recommended Practice: Keep at least one extra pre-oiled filter for quick swaps during long, dusty rides.
- Only use quality foam filtersavoid cheap alternatives that may compromise filtration and fitment.
