TWIN AIR Air Filter - 150003: designed for demanding motocross riders, this multi-layer filter combines a patented design with a rigorous selection of foams to protect the airbox without restricting airflow. Ideal for use on motocross tracks, it focuses on simplicity and reliability for both training sessions and competitions.

• Triple layer foam: a first airy foam captures dust, sand, and large debris; a second denser layer retains fine particles while maintaining airflow.
• Third fireproof layer: allows for the removal of the original flame arrester if necessary.
• Specific adhesive: the bonding of the foams and the casing resists solvents and petrol, ensuring durability even after maintenance.
• Volume gain: slightly more compact than the original element to free up volume in the airbox and promote airflow circulation.
• Breathable seal: maximum contact surface with the casing to ensure sealing and limit infiltrations.
• Bonded assembly: eliminates the risk of deposits between layers, facilitating cleaning and reuse.
