*Please note: May not apply to all kits

Plumbed into a vehicle's PCV system to capture the excess crankcase vapors, residual oil mist and moisture from reentering the intake tract
Vehicles from the factory vent these excess crankcase vapors, residual oil mist and moisture right back into the intake manifold which could cause detonation, oil deposits to form in the intake tract including the valves themselves and from lowering the efficiency of the intercooler in intercooler equipped vehicles
Increases engine performance from cleaner intake air
Air-Oil Separators have billet aluminum bodies with internal baffling and mesh media
Includes heavy duty brass inlet and outlet fittings, Fuel/Emission/PCV Vapor hose, stainless steel mounting bracket and billet aluminum mounting clamp for the body of the separator
Some Vehicle crankcase ventilation systems require that 2 Air-Oil Separator bodies be used to properly capture and ventilate the system

Moroso Air-Oil Separators are available in 2 sizes, not all kits are available with both size body

Air-Oil Separator Kits, Large Body
The original size, 43% more capacity than the Small Body Version
Features a bottom drain with elbow that makes draining the collected oil virtually mess-free
Polished body can be chromed, painted, or powder coated for a custom look

Air-Oil Separator Kits, Small Body
Smaller size fits in more applications and some customers prefer the smaller size body
Two piece body unscrews for draining
Available with a polished or black anodized finishLearn More

Metco Motorsports Valve Cover Breather

 2003-2004 Mustang Cobra, 2007 & Newer Shelby GT500, Mercury Marauder

An Original Metco Motorsports Design!

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.

Note 1:  This breather will not fit the New Edge Mach 1 4V application due to inadequate hood clearance.

Note 2:

  This breather stand is also available with a male #10AN connection at the top instead of the provision for the breather element.  This configuration is designed for use in a custom crankcase evacuation system or for use with a vacuum pump.  Please see PN MBR0004-10AN listed elsewhere in this section.
