Shop parts for a 2022 Husqvarna FX350 Dirt Bike.
The 2022 Husqvarna FX350 is renowned for its strong midrange power and cross-country versatility. To keep your FX350 delivering top performance, routine air filter maintenance is crucial. Below is a MotoSport-exclusive guide for cleaning and replacing your FX350’s air filter—ensuring optimal airflow and engine protection tailored to this model.
Why Air Filter Maintenance Matters
- Protects your engine from damaging debris, dust, and dirt
- Ensures consistent power delivery and throttle response
- Maintains fuel efficiency for long rides and races
How Often Should You Service the Air Filter?
- For the 2022 FX350, clean and re-oil the air filter after every dusty ride or race
- Replace the filter if damaged, torn, or overly worn
- During very sandy or muddy conditions, inspect mid-ride for excessive clogging
What You Need
- Motocross-specific biodegradable air filter cleaner and air filter oil
- Warm water and mild soap (for rinsing)
- Clean, lint-free towels
- Gloves to protect your hands from grime and chemicals
- Replacement air filter (if the original is beyond cleaning)
Step-by-Step Air Filter Removal
- Remove the seat by unscrewing the rear seat bolt and sliding the seat back.
- Access the airbox on the right side. The FX350’s simple side cover latch makes this process tool-less and fast.
- Unclip the air filter cage from its tabs. Note: The 2022 FX350 uses a robust twin-air foam filter design. Ensure you note filter orientation for proper reinstallation.
Cleaning the Air Filter
- Usher the air filter gently off the cage. Inspect for rips or tears. If damaged, use a new filter.
- Soak the filter in a bucket of specialty foam air filter cleaner (biodegradable recommended). Massage the cleaner through the foam. Avoid using gasoline, as it can degrade the filter material over time.
- Rinse thoroughly with warm water until no dirt or cleaner remains.
- Squeeze (do not wring or twist) the filter gently to remove excess water.
- Allow the filter to dry completely before oiling. This is critical for the FX350’s high airflow requirements.
Oiling and Reinstalling
- Apply a premium motocross air filter oil evenly. Work the oil in thoroughly to ensure all pores are sealed from dust while allowing air to pass. The FX350 benefits from proper, not excessive, oiling–to avoid hampering airflow.
- Reinstall the air filter onto the plastic cage, ensuring it seats fully and securely on all edges. The Husqvarna system uses tabs–ensure these snap back in place firmly.
- Double-check the fit by gently pulling on the filter. Any looseness can let dirt pass directly into the engine.
- Reattach the airbox cover and reinstall the seat.
Special FX350 Notes
- The 2022 FX350’s airbox design is tuned for cross-country riding. Keeping the filter clean maximizes the model’s signature throttle response and top-end power.
- Owners who perform airbox ventilation mods (removing top and side covers, as some do for increased air flow) should increase filter inspection frequency, as more debris may enter the airbox.
When to Replace
- Swap your FX350 air filter if it shows tears, hardening, or if constant cleaning fails to restore proper color and flexibility.
- Always use genuine or high-quality aftermarket filters designed specifically for the Husqvarna FX350 for best fit and sealing performance.
Regular air filter cleaning and timely replacement will keep your 2022 Husqvarna FX350 running at peak performance, ride after ride. For genuine and performance air filters, along with all FX350 parts, MotoSport has you covered.
