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.

A fluid directing assembly includes partitions which define fluid directing runners. The partitions extend from a first portion and include an engagement member extending therefrom. The engagement members extend from the partitions such that an interference fit is formed between the first portion and a second portion of the module. The engagement members assure that fluid communication between runners adjacent the apertures formed by the separate portions is prevented.

An injection molded screw retainer is employed on an air intake manifold system to retain screws which connect an active system body to a manifold lower assembly. The retainer is substantially &ldquo;L-shaped&rdquo; and includes a retaining portion and a substantially perpendicular attachment portion. The retaining portion includes a substantially hemispherical feature positioned substantially over the head of the screw. The oversized attachment portion is inserted within a pocket in the active system body. Ultrasonic energy applied by a sonic welding process slightly melts the outer surface of the attachment portion, creating a weld interference between the attachment portion and the pocket, securing the attachment portion within the pocket.
