Twin Air pre-oiled air filter 158601FRX KTM 990 Adenture

A patented design, a rigorous choice of materials and extreme manufacturing quality guarantee Twin Air filters unrivalled performance and protection. This makes them the preferred choice of most top-level riders in national and international championships.

- A first layer of aerated foam traps dust, sand and impurities
- A second, denser layer of foam traps the finest particles, while facilitating airflow.
- Specially developed for Twin Air filters, the glue that holds the foam together is resistant to various solvents and petrol.
- Twin Air filters are significantly smaller than the original elements, to increase the volume available in the airbox and promote airflow.
- Unique "breathing seal" design ensures maximum contact surface with the filter housing body
- Bonding of the two foam shells together eliminates the risk of dust and impurities becoming lodged between the two layers
