Abstract
A filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.
