The Moroso filtered valve cover breather is a clamp-on, no-hood breather with a 2" inner diameter that offers a larger filtered vent opening for valve covers requiring a clamped connection. Its clamp-on design accommodates thicker cover flanges and larger oil-return openings, supplying a visible, filtered crankcase vent without adding a hooded fitting or separate plumbing.
