Supercharged engines like the 2007-2014 Shelby GT500 push heavy crankcase vapor, oil mist, and moisture through the PCV system and back into the intake tract. Left unchecked, those contaminants cause detonation, carbon buildup on valves, and reduced intercooler efficiency. Moroso's air-oil separator kit intercepts those vapors before they reach the intake, keeping combustion clean and your GT500's supercharged 5.4L breathing fresh air on every pull.
Billet aluminum construction with internal baffling. Each separator body features a polished billet aluminum housing packed with internal baffling and mesh media that strips oil and moisture from blow-by gases. The separated oil collects in the body rather than coating your intake manifold, valves, or intercooler core.
Two body sizes to fit your install. Moroso offers this kit in a large body version and a small body version. The large body carries 43% more capacity than the small body, features a bottom drain with an elbow fitting for virtually mess-free draining, and has a polished finish that accepts chrome, paint, or powder coat. The small body fits tighter engine bays, uses a two-piece design that unscrews for draining, and comes in polished or black anodized finish. Both versions include heavy-duty brass inlet and outlet fittings, fuel/emission/PCV vapor hose, a stainless steel mounting bracket, and a billet aluminum mounting clamp.
Plug-and-play PCV integration. The kit plumbs directly into the factory PCV system without permanent modification to OEM hardware. No tuning changes are required after installation.
Product Benefits
- Cleaner Intake Air: Captures oil mist and moisture before they re-enter the intake manifold, reducing the risk of detonation and carbon deposits.
