A water filter cartridge has an end cap with inlet and outlet nozzles extending from the end cap. A lateral support extends laterally from at least one of the nozzles. A projection extends from the lateral support toward a receiving manifold to cooperate with the manifold during use. The lateral support is offset from the end cap so the projection is vertically offset from an end of the cartridge and laterally offset from and supported from the nozzles.

A filter assembly for authenticating a filter cartridge includes a filter housing and an optical scanner mounted to the filter housing. A controller uses the optical scanner to take one or more digital images of the filter cartridge and obtain digital coded data identifying the filter cartridge. Specifically, the controller locates a functional locator on the filter cartridge, determines a location of an identifying region on the filter cartridge, reads the digital coded data by interrogating the identifying region with the optical scanner, and determines that the filter cartridge is authentic based at least in part on the digital coded data.

A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A transmission oil filter is assembled from a filter element, a base, and a cover. Each of the three pieces extends beyond the filtration media to form an inlet channel. The inlet channel is low enough to fit under a valve body. Placing the inlet in this channel ensures that the inlet draws transmission fluid at road gradients and acceleration rates at which an inlet under the filtration media would draw air.

A filter housing assembly for fluid filtration which may be attached to, and removed from, a filter base by a push-actuated release. The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.
