Abstract

Various embodiments provide for a filter assembly. The filter assembly includes a filter housing, a filter element, and a cover. The cover includes a first cover end and a second cover end disposed axially away from the first cover end. A second coupling member is adjacent to the second cover end. The second coupling member is configured to engage a first coupling member to couple the cover and the filter housing. A biasing member is coupled to the first cover end. An interface plate is configured to press against a first endplate of the filter element to secure the engagement of a first engagement portion of a filter seal member of the filter element and a second engagement portion of a housing seal member of the filter housing.
