A second filter portion includes a second generally-tubular frame and a second pleated filter media disposed adjacent to the second generally-tubular frame. A coupler is provided for connecting the first filter portion to the second filter portion and establishing fluid communication between the first and second filter portions when connected. The coupling includes a first coupling portion including a side wall defining a receiver, as well as a lug clip disposed adjacent to the receiver.
