An air induction system for attenuating sound produced by an engine, a housing defining a working chamber for attenuating sound produced by the engine. The air induction system further includes a tube having a first end extending into the working chamber and a second end to be in fluid communication with the engine. The air induction system further includes a first flange radially extending from the tube and disposed in the working chamber. The tube, the housing and the first flange cooperate to define a resonator operable to attenuate sound produced by the engine.
