Abstract
An underhood air cleaner (10) includes a plastic housing (12) having an inlet (14) for receiving dirty air, a filter element (18) for filtering the air, and an outlet (42) for discharging clean filtered air. A plastic outlet duct (40) is butt welded (50) to the housing outlet (42) in axially non-overlapping relation, to eliminate axial overlap previously required for a hose clamp, to reduce the amount of underhood space required by an engine air cleaner in the axial direction.
