Abstract
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.
