Designed for motocross enthusiasts and owners of vintage machines, the TWIN AIR air filter (ref. 152117) focuses on a multilayer foam construction and careful implementation to protect the airbox and intake. Its design prioritises progressive filtration of dust and sand while maintaining an airflow suitable for the needs of a vintage 2-stroke engine.

• Triple layer foam: first layer is airy to trap large particles, second is denser to capture fine particles, third layer is fire-retardant.
• Specific adhesive: adhesive developed for Twin Air that is resistant to solvents and petrol, ensuring the cohesion of the foam panels.
• Compact design: slightly smaller than the original element to increase the available volume in the airbox and promote airflow.
• Breathable seal: maximised contact surface with the filter housing for good sealing and reliable retention in dusty conditions.
• Bonded assembly: eliminates gaps between layers to prevent the accumulation of impurities.

Ideal for vintage YZs and other motocross machines where dust protection is crucial without complicating maintenance. Version: Standard. Manufacturer reference: 152117.
