Twin air 158028 Air filterRef : TA00353A / 1096913

TWIN AIR Air Filter - 158028: specially designed for motocross and enduro riding, this multi-layer filter effectively protects the engine from dust, sand, and impurities while maintaining suitable airflow for modern filter housings. Careful design and assembly ensure lasting reliability in muddy or sandy terrains.

• Triple layer foam: a first airy foam retains large grains and debris, a second denser foam stops fine particles without hindering airflow, and a third flame-retardant layer allows for the removal of the original anti-backfire screen.
• Specific Twin Air adhesive: adhesive developed for filters, resistant to solvents and gasoline to ensure the cohesion of layers even after repeated cleanings.
• Optimized format: slightly more compact element than the original to free up volume in the airbox and promote internal airflow.
• High surface breathable seal: ensures maximum contact between the filter and the housing body, limiting unwanted infiltrations.
• Glued assembly of foam envelopes: eliminates pockets where dust could settle between layers.

Filter version: Standard. Main compatibilities: BETA RR 450 4T ENDURO RACING (2012), BETA RR 450 4T ENDURO (2012), BETA RR 450 4T CROSS COUNTRY (2012). A part to keep in your toolbox for regular maintenance of the filter housing during your off-road outings.
