Abstract
An air resonator for an air intake system includes a plurality of serially positioned increasing volume chambers. Air passing to the engine passes through these chambers. Noise passing from the engine back towards the source of air will also pass through these increasing volume chambers. As the noise serially passes through the increasing and then decreasing volume, the noise is dissipated.
