ABSTRACT:
An air filter assembly for the air intake system of an internal combustion engine includes a housing which receives a removable, replaceable filter cartridge. The lower end of the filter housing includes a hub assembly which defines the outlet opening from the housing. A removable, replaceable bridge assembly extends into the housing from the outlet opening and provides an axial support for the filter cartridge. The bridge and hub assembly are provided with cooperating releasable retaining mechanism comprising a rib projecting into the outlet opening which engages a circumferentially extending ring on the bridge assembly to prevent the bridge assembly from being pulled into the housing. The bridge is also provided with deflectable arms which also engage the rib to prevent the bridge from being pushed out of the housing unless the arms are deflected when the bridge is to be withdrawn from the housing.
