- Billet Valve Cover Breathers
- Fits 1.22'' Breather Hole
This valve cover breather assembly is modeled after the popular Metco breathers designed for factory valve covers, but this unit fits aftermarket valve covers with the standard 1.22' breather hole.
Like all Metco breathers, the base is CNC-machined from billet aluminum for precise fit, and then microfinished for surface protection and good looks. The removable filter element is a high-quality reusable unit from S & B Filters, which is retained in the filter base by the specially-machined retention groove at the top of the base.
The purpose of this valve cover breather is to vent unwanted accumulation of pressure in the crankcase, and to provide maximum circulation of ambient air in the crankcase to reduce oil temperatures. The installation of this breather will contribute to increased engine oil life and reduce the possibility of failed engine seals resulting from excessive crankcase pressure. This breather will reduce the effectiveness of the vehicle's PCV system, and it is not emissions-legal.
Kit includes (1) breather assembly and (1) rubber valve cover grommet. Total height above the valve cover is approximately 3.25'.
