This valve cover breather is designed to fit a standard PCV rubber grommet with the 3/4" opening. It is a press-fit (just like a PCV valve) and installs in seconds. Like all Metco breathers, the stand is precision-machined from billet aluminum. The high quality S & B filter element is captured securely by a retaining ring machined into the top of the stand. Image 3 (above) shows this breather installed in the PCV location at the rear of the drivers side valve cover on the 2003-2004 Mustang Cobra application. This breather will fit other applications as well - please contact us if you have questions. Note 1: The total height of this breather above the valve cover is approximately 3.0". Please confirm that you have vertical clearance above the PCV opening prior to ordering.
