TWIN AIR Air Filter - Manufacturer Ref. 158210

Designed for off-road practices, this TWIN AIR Standard filter features a multi-foam construction and selected materials to protect the engine from dust and sand. Its compact design allows for more free volume in the airbox while aiming to optimize airflow — a common choice among motocross riders concerned with reliability on muddy or dusty tracks.

• Double layer of foam: a first airy layer captures larger impurities, while the second, denser layer limits fine particles without excessively obstructing airflow.
• Bonded assembly between the two foam layers to prevent dust intrusion between the layers.
• Specific adhesive developed to resist solvents and gasoline, ensuring the cohesion of elements even after cleaning.
• Intentionally more compact profile than the original element to increase available space in the airbox.
• "Breathable" seal to maximize the contact surface with the filter housing and improve mechanical sealing.

Ideal for the Cross universe, this filter is aimed at enthusiasts and competitors seeking effective protection and proven longevity in off-road conditions. Easy to install; follow the manufacturer's recommendations for maintenance and any potential oil impregnation.
