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.

Filter assembly with sound attenuation member and related method of manufacture

A filter element includes support grid secured about its periphery edges to a periphery frame member. A pleated filter media is secured to the frame member and is sized and positioned to fully cover the filter fluid aperture. The support grid is positioned such that it is effective in providing support to the filter media against fluid forces. At least one elongated comb member is provided and includes a plurality of spaced tapered teeth protruding outwards towards the filter media. The teeth are sized and spaced to be received into at least a portion of grooves present between the pleats of the filter media. The teeth of the comb member are sized and spaced to regulate filter media pleat separation and spacing.
