The 2018 Sherco 450SEFFAC comes equipped with a flame-laminated, dual-layer foam air filter designed for high performance and durability, which is vital for protection against dirt intrusion in off-road conditions. Ensuring your air filter is clean and in optimal condition is essential for maintaining engine performance – neglecting the filter can result in loss of power, increased engine wear, and costly repairs.
Key Features of Your Sherco 450SEFFAC Air Filter
- Dual-layer flame-laminated foam for advanced filtration & maximum airflow.
- Full open-cell structure stops ultra-fine dirt while maximizing breathable surface area.
- Heavy-duty glue bonding resists harsh solvents – perfect for repetitive cleaning cycles.
- Wide, soft sealing ring ensures positive, dust-proof airbox contact.
- OEM fit guarantees the filter sits perfectly – never force or stretch the filter.
Cleaning Your Air Filter
- Remove the seat & air filter cage. Lift filter gently to avoid dropping dirt into the intake.
- Tap or lightly brush away excess dust & loose debris.
- Submerge in a dedicated foam filter cleaner or mild, non-petroleum detergent. Gently massage – do not wring or twist – to prevent tearing.
- Rinse with clean water until no residue remains. Squeeze out liquid, again avoiding any forceful action.
- Dry fully – air dry away from direct sunlight or excessive heat.
- Inspect for tears, glue separation, or hardened foam. If compromised, replace immediately.
- Once dry, apply a premium foam filter oil throughout. Work oil into all foam cells until evenly pigmented – never leave dry spots or clumping.
Replacing the Air Filter
- Install clean, oiled filter on the air filter cage, ensuring full engagement with the cage tabs – check sealing ring integrity.
- Fit assembly into the airbox, verifying complete seal all around. Rotate gently to ensure uniform pressure.
- Secure airbox cover & seat before riding.
Special Considerations for the 2018 Sherco 450SEFFAC
- Factory Edition: Uses high-flame retardant foam per OEM specifications, especially important for endurance and race settings.
- Greaseless sealing ring (on select aftermarket filters) boosts gasket reliability without messy filter greases.
- Check after every ride – especially in heavy dust or water crossings. This model's open-cell filter design is efficient but sensitive to clogging.
When to Replace Your Air Filter
- Visible tears, separation, punctures, or warping
- Repeated cleaning has degraded foam elasticity or shape
- Loss of filter oil absorption or persistent discoloration
- After extreme dust, long race intervals, or muddy conditions
The right maintenance keeps your 2018 Sherco 450SEFFAC riding hard with maximized engine life. Always inspect and clean your air filter regularly, and choose OEM fitment or certified high-performance alternatives for best results.
