Abstract
A vehicle air filter housing having a broad band tuner. The housing is formed from a tray having a divider wall defining an unfiltered air induction chamber and a tuner chamber. A cover securable to the tray includes a second divider wall defining a filtered air chamber and a flow path chamber. A filter member provides a seal between the tray and the cover, and holds an air filter between the unfiltered air chamber and the filtered air chamber. A plate securable to the flow path chamber has a plurality of perforations. Air inducted through the inlet passes through the air filter and flows through the flow path chamber at a velocity whereby the filtered air passes over the perforated plate and predetermined frequencies pass through the plate perforations for attenuation in the tuner chamber. The tuners in the tuner chamber may be sized to attenuate different frequencies.
