Twin Air Motorcycle air filter Yamaha Yz 250

A patented design, a rigorous selection of materials, and extreme manufacturing quality guarantee Twin Air filters unmatched performance and protection levels to this day. This makes them the preferred choice of most top-level riders in both national and international championships. A first layer of breathable foam traps dust, sand, and impurities. The denser second layer of foam stops the finest particles while promoting airflow. A third flame-retardant layer allows for the removal of the original backfire screen. Specially developed for Twin Air filters, the adhesive that holds the foam pieces together resists various solvents and gasoline. Twin Air filters are noticeably smaller than the original elements to increase the volume available in the airbox and enhance airflow. The unique "breathable seal" design ensures maximum contact surface with the filter housing. The adhesion of the two foam shells eliminates the risk of dust and impurities settling between the two layers.
