The filter element of claim 1, wherein the one or more keyed fingers are axially outwardly and radially offset from the threaded aperture. 4. The filter element of claim 1, wherein the radially extending arm portion terminates at the a radially inner end, and at an axially inwardly extending end portion. 5. The filter element of claim 1, wherein the open space is axially and radially offset from the threaded aperture and configured to receive a cantilevered bridge portion of a latching body associated with the filter head. 6. The filter element of claim 1, wherein the one or more keyed fingers protrude radially inwardly. 7. The filter element of claim 1, wherein the one or more keyed fingers include four keyed fingers. 8. The filter element of claim 1, wherein the one or more keyed fingers form an axially extending hoop. 9. The filter element of claim 1, further comprising a second cap at a second open end of the canister. 10. A filter element for installation in a filter element adapter assembly with a keyed retractable shroud for covering threads configured to receive the filter element, the filter element comprising: a filtering media compiled in a cylindrical pack defining a longitudinal axis and having an outer radial surface, an inner radial surface defining a fluid chamber, a first axial end face, and a second axial end face; anda first end cap having a main body with an axially inward side and an axially outward side, the end cap comprising:an annular shelf on the axially inward side on which the first axial end face of the filtering media sits,a threaded central passage positioned radially inward of the annular shelf in fluid communication with the fluid chamber of the filtering media, andone or more keyed fingers coupled to the main body and protruding axially from the main body, the one or more keyed fingers positioned on the axially outward side of the main body and radially outward of the threaded central passage,wherein the one or more keyed fingers include a radially inwardly extending arm portion spaced axially outwardly from the axially outward side of the main body to form an open space between the radially inwardly extending arm portion and the axially outward side, the radially inwardly extending arm portion having a radially inner end that faces radially inwardly toward an open interior space that is axially outwardly from the threaded aperture, the radially inner end being disposed between gaps on circumferentially opposite sides thereof that communicate with the open interior space. 11. The filter element of claim 10, wherein the one or more keyed fingers include a terminal end portion extending axially toward the filter media. 12. The filter element of claim 10, wherein a radially inward portions of the one or more keyed fingers is attached to adjacent portions of the end cap main body. 13. The filter element of claim 10, wherein the one or more keyed fingers extend radially inwardly form an annular peripheral portion of a canister enclosing the filtering media. 14.
