Abstract

An air induction system (10) comprises a flow body (14) and a filter housing (16). (FIG. 1). The filter housing (16) has an opening (26) of a first shape. (FIG. 1). A filter support (34) has an outer periphery (38) of about the first shape and an inner periphery (42) of a second different shape. The support is operatively connected to the housing (16). (FIG. 1). A symmetric filter (46) is also connected to the support (34). (FIG. 1). The air induction system attenuates engine noise for a motor vehicle.
