An air induction assembly includes a tuning tube that is integrally formed with an air duct having a distal tube end extending into a resonance chamber. The air duct includes a shoulder portion that transitions into a base end of the tuning tube. The shoulder portion has a greater diameter than the tuning tube and defines an external duct surface. The resonance chamber includes an opening for receiving the tuning tube. A flange surrounds the opening and defines an external resonance chamber surface. The external resonance chamber surface abuts against the external duct surface to define an attachment interface. The assembly is welded at the attachment interface to securely attach the resonance chamber to the air duct.

Method and apparatus for attaching a resonance chamber to an air induction component

An air induction system comprises flow body ( ) and a filter housing ( ). The filter housing ( ) has a first housing portion ( ) and a second housing portion ( ) in communication with the air flow body ( ). A filter ( ) is disposed in the filter housing ( ). A connector comprises a wing ( ) mounted to a post ( ) extending from the first housing portion ( ) and a slot ( ) on the second housing portion ( ). (FIG. ). The first housing portion ( ) has at least one cutout ( ) adjacent post ( ). (FIG. ).

Moldable twist lock snap fit design for plastic air cleaner

An air induction system ( ) comprises a flow body ( ) and a filter housing ( ). (FIG. ). The filter housing ( ) has an opening ( ) of a first shape. (FIG. ). A filter support ( ) has an outer periphery ( ) of about the first shape and an inner periphery ( ) of a second different shape. The support is operatively connected to the housing ( ). (FIG. ). A symmetric filter ( ) is also connected to the support ( ). (FIG. ). The air induction system attenuates engine noise for a motor vehicle.
