Direct-injection and forced-induction F-150 engines push crankcase vapors, oil mist, and moisture back through the PCV system and directly into the intake tract. Left unchecked, that contamination bakes onto intake valves, reduces intercooler efficiency on the 3.5L EcoBoost, and can contribute to detonation. Moroso's air-oil separator kit plumbs into the factory PCV system on your 2011-2014 F-150 3.5L EcoBoost or 5.0L, intercepting contaminants before they ever reach the intake manifold.
Billet aluminum construction with internal baffling. Each separator body is machined from billet aluminum and fitted with internal baffling and mesh media that strip oil mist and moisture from crankcase blow-by gases. Cleaned vapor continues on to the intake while captured oil collects in the body for periodic draining.
Complete kit, ready to install. Moroso includes heavy-duty brass inlet and outlet fittings, fuel/emission/PCV vapor hose, a stainless steel mounting bracket, and a billet aluminum mounting clamp for the separator body. No sourcing additional hardware or fabricating brackets to get this on the truck.
Two body sizes to fit your preference and available space. The large body is the original Moroso size, offering 43% more capacity than the small body version. It features a bottom drain with an elbow fitting that makes emptying collected oil virtually mess-free, and the polished finish can be chromed, painted, or powder coated. The small body fits tighter engine bays and is available in a polished or black anodized finish; its two-piece design simply unscrews for draining.
Product Benefits
- Cleaner Intake Air: Captures oil mist, moisture, and crankcase vapors before they enter the intake manifold.
- Protects Intake Valves: Reduces carbon and oil deposits on valve faces and intake surfaces.
- Intercooler Protection: Keeps oil contamination out of the intercooler on EcoBoost-equipped trucks.
- Reduces Detonation Risk: Cleaner, drier intake charge lowers the likelihood of detonation from oil contamination.
- Billet Aluminum Body: Internal baffling and mesh media for effective oil and vapor separation.
- Complete Hardware Included: Brass fittings, PCV hose, stainless bracket, and billet clamp in the box.
- Large Body Option: 43% more capacity than the small body, with a mess-free bottom drain elbow.
- Small Body Option: Compact fitment with a two-piece body that unscrews for easy draining; polished or black anodized finish.
- Customizable Finish: Polished large body accepts chrome, paint, or powder coat.
Note: Fits 2011-2014 F-150 with 3.5L EcoBoost or 5.0L engines. Available in three configurations: small polished body, small black anodized body, or large polished body. Some vehicle crankcase ventilation systems require two separator bodies for proper capture and ventilation.
