The filter inlet shape has been designed to increase (maximize) the amount of cold air drawn in. The highly galvanized mesh together with the filtering surface is characterized by maximum efficiency with very good filtering properties. The carbon housing provides excellent thermal insulation. The housing is removable, which allows the filter to be used for a very long time by systematically cleaning it. The use of dedicated SIMOTA cleaning oils ensures extended filter life. Please select the mounting diameter from the top menu. The kit includes a filter cartridge.
