The TWIN AIR air filter (manufacturer reference 152122) is a replacement element designed for vintage machines in the Cross category. Built around a multi-foam structure, it effectively protects the airbox while facilitating the airflow necessary for the engine.

• Triple-layer construction: a porous foam at the entry retains dust, sand, and large debris; a second denser foam captures fine particles without obstructing airflow; a third flame-retardant layer allows for the removal of the original flame arrester screen if necessary.
• Specific Twin Air adhesive: ensures the cohesion of the different foams and resists solvents and gasoline present in the airbox.
• Optimized dimensions: slightly more compact than the original element to free up volume in the airbox and promote engine breathing.
• “Breathable” seal: maximum contact surface with the housing to limit lateral leaks and ensure consistent sealing.
• Adhesive assembly between envelopes: prevents dust accumulation between layers and facilitates maintenance.

Available version: Standard. Universe: Cross / Vintage. Common compatibilities (examples): YAMAHA YZ 400 Competition 1979, YAMAHA YZ 250 1979. Ideal for riders seeking robust filtration and simplified maintenance on their vintage machines.
