The Moroso filtered valve cover breather is a clamp-on, half-hood style vent with a 1.5 inch inner diameter, offering a larger filtered outlet for valve cover tubes. The half-hood provides partial protection for the filter element while the clamp-on installation keeps it serviceable. It's suitable for applications that require a bigger breather opening and basic oil separation.
