Moroso Air Oil Separator

MOR 85484
These Moroso Air-Oil Separator Tanks are plumbed into a vehicle's breather/PCV system to capture excess crankcase vapors and the residual oil mist from re-entering the intake track. There are versions available for factory configurations, vacuum pumps, and universal installations.
This kit has two tanks: the first collects the excess crankcase vaporsresidual 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-this kit is the only one that accomplishes this
Capturing this oil mist before it re-enters the engine reduces detonation and deposits on the intake tract, including the valves themselves and from lowering the efficiency of the intercooler
Ethanol enriched fuels put off more moisture during the combustion process-these are an excellent tool for collecting this extra moisture
Includes 3/8" and 1/2" 90º inlet and outlet fittings, 66" of 3/8" and 1/2" rubber hose for plumbing the inline and a billet aluminum mounting clamp for the body
Each separator has a bottom drain with an elbow that makes draining the collected oil virtually mess free
Genuine Subaru throttle body gasket included
