Abstract
An air filter assembly for an engine includes a filter element, a sound attenuation member and an end cap. The filter element may be a cylindrical filter element defining a hollow interior. The sound attenuation member may extend into the hollow interior of the cylindrical filter element. The sound attenuation member may include a flange at a first end thereof. The flange may have a diameter greater than a diameter of the hollow interior. The end cap may be secured to the cylindrical filter element and may function to fix the sound attenuation member relative to the filter member. The sound attenuation member is operative for reducing engine noise travelling through the air filter assembly.
