Keeping your 2019 Sherco 250SEFFAC running at peak performance begins with proper air filter maintenance. The air filter protects your engine from airborne dirt, sand, and grime encountered during off-road riding. For the 250SEFFAC, Sherco uses a dual-stage foam filter system, which demands routine care for performance and engine longevity.
Why Air Filter Maintenance Matters for Your Sherco 250SEFFAC
- Dual-stage foam filter (outer/coarse, inner/fine) delivers both high airflow and filtration — ideal for technical trails and race use.
- Flame-laminated foam is used, ensuring durability and resistance to degradation while maximizing protection from debris.
- Specific OEM fit and wide sealing ring help block out fine dust, a notable advantage in harsh conditions.
- Maintaining a clean air filter is essential for consistent throttle response and protecting your Sherco's engine from accelerated wear.
How Often to Clean or Replace the Sherco 250SEFFAC Air Filter
- After every ride in very dusty, sandy, or muddy conditions
- Every 2-3 rides in standard trail environments

Preparation – Tools & Supplies
- Clean workspace & gloves
- Foam filter cleaner/degreaser
- Foam filter oil specific for dual-stage filters
- Replacement filter (OEM or high-quality aftermarket — ensure fit for SEF models from 2014-2021)

Step-by-Step: Cleaning/Changing Your Sherco 250SEFFAC Air Filter
- Remove the seat by unlocking and lifting it off the chassis. Locate and carefully unclip the air box cover.
- Detach the air filter cage: Loosen and remove the filter cage holding screw. Avoid dropping dirt into the intake tract.
- Check for debris inside the air box. Wipe clean with a damp towel if needed before reinstalling a clean filter.
- Pre-clean inspection: Inspect your air filter for tears or signs of deterioration. Replace the filter if you see damage or hardening.
- Cleaning:
- Soak the filter in manufacturer-recommended foam air filter cleaner or a mild degreaser. Gently massage (do not wring or twist) to avoid damaging seams.
- Rinse thoroughly with water until all soap and dirt are removed.
- Allow the filter to air dry completely – never use compressed air or excessive heat.
- Oiling:
- Apply foam air filter oil – fully saturate, then squeeze out excess oil so it's evenly coated but not dripping.
- Pay attention to sealing surfaces and filter seams for a uniform coat.
- Reinstallation:
- Reattach the filter to the plastic cage, ensuring all edges/seams are properly sealed.
- Secure the filter assembly back into the air box, reinstall the cover, and ensure the seat is firmly locked.
What Makes the 2019 250SEFFAC Air Filter Unique?
- Flame-retardant and dual-layer design for superior protection in high-heat, high-dust riding — key for the SEF-F/SEFFAC four-stroke engines.
- The OEM fit is matched by aftermarket brands, but always confirm compatibility for SEF Factory models from 2014-2024 for proper sealing and protection.
- Wide, flexible sealing rings & heavy-duty glue in these filters are specifically designed to handle tough enduro riding and extended maintenance intervals.
Pro Tips for Sherco Owners
- Keep a spare pre-oiled filter in a sealed bag for fast swaps on multi-day rides.
- Inspect the air box and intake track for signs of dust bypass, paying special attention after very dusty rides.
- Apply a thin bead of air filter grease on the sealing edge for extra protection, especially in extremely fine dust conditions.
