An air diffuser (20) for an air intake system of an internal combustion engine. The air intake system includes a throttle body (22) up stream from an intake manifold (24), with the air diffuser (20) mounted between them. The air diffuser (20) includes vanes (62, 64) extending into its main bore (52) in order to diffuse and redirect the air flowing from the throttle body (22) into the intake manifold (24). The diffusion and redirection of the air reduces the noise emanating from the intake manifold (24) for particular engine operating conditions.
