Designed for enduro and motocross, the TWIN AIR air filter (manufacturer part number 158039) combines proven engineering and selected materials to provide optimal protection for your engine in the most demanding terrains. Its multi-foam construction ensures progressive filtration: coarse dirt is trapped in the first layer, while the denser second foam stops fine particles without hindering airflow. Designed for riders who push their machines, it facilitates volume management in the airbox thanks to a slightly reduced format compared to the original.

• Triple layer of foam: ventilated pre-filter, dense foam for fine particles, and flame-retardant layer.
• Third flame-retardant layer allowing, if necessary, the removal of the original flame arrestor.
• Specific Twin Air adhesive resistant to solvents and petrol for durable foam retention.
• Patented breathable seal for maximum contact with the filter housing and optimal sealing.
• Bonded assembly between envelopes that prevents dust infiltration between layers.
• Version: Standard — suitable for motocross and off-road applications.
• Manufacturer reference: 158039.

Ideal for riders seeking reliable filtration and optimised airflow in dusty or sandy terrains.
