Moroso Oil Catch Tanks

Air/Oil Separator:
From the factory excess crankcase vapors, residual oil and moisture are vented back into the intake manifold and crankcase ventilation system. Capturing this oil mist before it reenters the engine reduces detonation and deposits on the intake track, including the valves themselves and from lowering the efficiency of the intercooler.

This is accomplished by having two tanks; the first tank collects the excess crankcase vapors, residual oil and moisture that are vented back into the intake manifold. The second tank collects the excess crankcase vapors, residual oil and moisture from each cylinder head. If both were plumbed into the same tank then the crankcase ventilation system could not operate the way it was designed to the Moroso Kit is the only Subaru air separator that accomplishes this.

The Billet Aluminum bodies of this Air Oil Separator kit compliment any engine compartment and can be polished, chromed or powder coated for a custom look. Each Separator has a billet aluminum clamp, a bottom drain with an elbow that makes draining the collected oil a mess-free proposition. Includes stainless steel mounting brackets, 1/2 inlet and outlet fittings, 66 of 3/8 diameter and 66 of 1/2 diameter rubber hose for plumbing the Air-Oil Separators inline. Also, two genuine Subaru throttle body gaskets are included in each kit.


Dry Sump Breather Tank:
Moroso all aluminum, lightweight tanks are equipped for easy hookup to a vacuum pumps or dry sump pumps. Hand-operated drain cock facilitates tank cleaning. Includes non-hooded, clamp-on-style filtered breather that traps oil while allowing air to escape freely. Mounting clamp and simple instructions are included.
