A first flap is pivotally mounted to support frame in the first opening. The first flap is displaceable between a fully outwardly open position, a fully inwardly open position and an intermediate closed position. Further, the flap is tuned to a resonance frequency of between 12 and 18 hertz characteristic of the wind throb generated by the vehicle in which the air extractor is mounted.
