Abstract
A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.
