An air cleaner assembly includes a filter element and a outer jacket. The filter element has a first end cap with a central opening therein for airflow communication with the filter interior. The second end cap is a closed end cap having spaced radially directed projections and spaced, axially directed projections. The outer jacket is selectively mountable and dismountable on the filter element upon axial relative movement between the jacket and the element. The jacket includes a locking member positioned to selectively engage the jacket with the second end cap radial projections and to secure the jacket on the filter element. The radial projections engage the jacket and support the jacket spaced from a remainder of the second end cap sufficiently to provide an airflow inlet arrangement. In one example, the locking member includes a bead circumferentially lining the inner wall of the jacket. Each of the radial projections on the second end cap selectively engages the bead. Engine air flow systems using an air cleaner assembly are described. Methods for installing and changing out a filter element in an air cleaner include tilting a filter element at an angle relative to a longitudinal axis of the housing, and after tilting the filter element, straightening the element and axially moving one of the element and the housing relative to the other two position the element inside of the housing.
