A fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an enclosing outer shell, a filtering element positioned within the outer shell so as to define an annular clearance space between the outer shell and the filtering element. A nutplate is assembled to the outer shell so as to close the outer shell and provide an internally-threaded mounting portion for attachment to the engine block mounting base. The sidewall which defines the threaded mounting portion is free of any flow openings therethrough. A seal arrangement including an inner seal positioned between the nutplate and the filter element and an outer seal positioned between the engine block mounting base and the nutplate is provided as part of the fluid filter assembly. The nutplate and inner seal are designed to cooperate with each other so as to define a plurality of flow passageways extending between the nutplate and inner seal and providing a flow path from the engine block mounting base to the annular clearance space.

[ What is claimed is:] [1.] A fluid filter assembly which is constructed and arranged to threadedly mount to a mounting base to receive a flow of incoming fluid to be filtered by a filtering element and to discharge said fluid downstream of said filtering element, said fluid filter assembly comprising:an enclosing outer shell having an upper formed channel;a filtering element positioned within said enclosing outer shell so as to define an annular clearance space;a nutplate having an annular sidewall with an upper, radially outer lip which is securely anchored into said formed channel and a threaded mounting portion constructed and arranged for assembly to said mounting base, said threaded mounting portion including a lower edge, said lower edge includes a plurality of spacer tabs extending axially from said lower edge in a direction away from said upper, outer lip portion;an inner seal positioned between said nutplate and said filtering element;an outer seal adapted to be positioned between said mounting base and said nutplate; andwherein said flow of incoming fluid flows through a flow passageway defined by said lower edge and by said inner seal.
