Direct-injection and modern PCV systems push crankcase vapors, oil mist, and moisture straight back into the intake manifold. On the 2011-2014 Mustang V6 3.7L, that means oil deposits forming on intake valves, reduced combustion efficiency, and the risk of detonation. Moroso's air-oil separator kit intercepts those contaminants before they reach the intake, keeping combustion cleaner and protecting long-term engine health.
Billet aluminum construction with internal baffling. Each separator body features a machined billet aluminum housing with internal baffling and mesh media that strips oil mist and moisture from crankcase vapors. Cleaned air continues on to the intake while captured oil collects in the body for periodic draining.
Complete hardware included. Each kit comes with heavy-duty brass inlet and outlet fittings, Fuel/Emission/PCV vapor hose, a stainless steel mounting bracket, and a billet aluminum mounting clamp. Everything needed for a clean, secure installation is in the box.
Two body sizes to suit your preference. Moroso offers this kit in a Large Body and Small Body version. The Large Body is the original size, offering 43% more capacity than the Small Body version. It features a bottom drain with elbow that makes draining collected oil virtually mess-free, and the polished finish can be chromed, painted, or powder coated. The Small Body fits tighter engine bays and comes in a polished or black anodized finish; its two-piece body unscrews for draining. Select your preferred size and finish from the available options.
