1. A filter element, comprising:
filter media; and
an endplate coupled to the filter media, the endplate comprising:
a first wall projecting radially outward of the endplate along an entire circumference of the endplate, the first wall having a pattern defining an outer circumferential uneven surface structured to mesh with a matching pattern formed on an inner surface of a shell housing when the filter element is installed in the shell housing, an upper surface of the first wall defining a gasket retaining lip, a lower surface of the first wall defining a housing support lip, the gasket retaining lip and the housing support lip each having a variable outer radius that matches a profile of the outer circumferential uneven surface, the housing support lip being a planar surface that is continuous along an entire perimeter of the endplate; and
a gasket retaining wall engaged with and extending axially away from the gasket retaining lip.
