TWIN AIR Air Filter - 154504: designed for motocross practices, this multi-layer foam filter incorporates Twin Air's fundamentals to protect the airbox while maintaining an optimised airflow. It is aimed at riders who want a reliable and easy-to-maintain intake element during muddy or sandy outings.

• Triple-layer construction: outer breathable layer to trap large debris (dust, sand), denser intermediate layer to stop fine particles while allowing air to pass, and a third flame-retardant layer.
• The presence of the flame-retardant layer allows, depending on the original setup, the removal of the factory-supplied flame arrestor if necessary.
• Specific adhesive developed for Twin Air: ensures the cohesion of the foams and resists solvents and petrol encountered during maintenance.
• Slightly reduced dimensions compared to the original element to free up volume in the airbox and promote airflow.
• “Breathable” seal providing maximum contact surface with the casing and bonding of the envelopes to prevent dirt accumulation between layers.
• Version: Standard
