Modern engines push crankcase vapors, oil mist, and moisture back through the PCV system and into the intake manifold. Left unchecked, that contamination coats valves, degrades intake efficiency, and can trigger detonation. Moroso's large-body air-oil separator for the 2005-2010 Mustang GT 4.6L intercepts those vapors before they reach the intake tract, capturing oil and moisture while returning filtered air to the system.
Large-body construction with 43% more capacity. Moroso's large-body separator offers significantly more internal volume than their small-body version, making it the better choice for engines with higher crankcase blow-by. The billet aluminum body houses internal baffling and mesh media that strip oil mist from crankcase vapors before the air continues downstream. A polished finish allows chroming, painting, or powder coating to suit a custom engine bay build.
Mess-free oil drain design. A bottom drain port with elbow fitting directs captured oil straight out without disassembling the unit or tipping it over. Routine maintenance stays clean and straightforward during every service interval.
Complete hardware included. Each kit ships with heavy-duty brass inlet and outlet fittings, fuel/emission/PCV vapor hose, a stainless steel mounting bracket, and a billet aluminum mounting clamp. Every component needed to plumb the separator into the factory PCV system is in the box.
