METCO 2003-2004 Cobra & 2007-2010 Shelby GT500 - Valve Cover Breather

METCO Valve Cover Breather
This valve cover breather assembly replaces the original oil fill cap found on the driver's side valve cover on the supercharged Cobra and Shelby GT500 applications.

The base of the breather is CNC-machined from billet aluminum for a precise fit, and the included silicone O-ring is specially designed to prevent seepage at the base of the filter. The filter base is microfinished for surface protection and good looks, and is easily hand-polished to a mirror-like appearance. The removeable filter element is a high-quality reusable unit from S & B Filters, and the filter is securely retained to the filter base by a specially-machined retention groove in the top of the filter 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.
