The TWIN AIR air filter (manufacturer ref. 152122) is a replacement part 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 inlet traps dust, sand, and large debris; a second denser foam captures fine particles without hindering airflow; a third fire-retardant layer allows, if necessary, the removal of the original flame arrester.
- Specific Twin Air adhesive: ensures the cohesion of the different foams and resists solvents and gasoline present in the airbox.
- Optimised 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 casing to limit lateral leaks and ensure uniform sealing.
- Bonded 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.
