Air/Oil Separator Tank 2-Breathers / 2 16an Fem

The Air/Oil Separator Tank 2-Breathers / 2 16AN Fem by MOROSO is engineered for serious engine builders and enthusiasts running forced-induction or high-performance naturally aspirated platforms. This separator addresses a critical problem in modified engines: excess crankcase pressure and oil vapor that bypass standard PCV systems. By trapping oil mist before it enters your intake manifold, this tank preserves fuel octane quality, prevents carbon deposits, and extends engine life—making it essential for turbo, supercharger, and aggressive street builds.

Dual breather ports allow simultaneous evacuation of crankcase gases from multiple sources, while the dual 16 AN female inlet ports provide robust, leak-free connections using standard braided hose and fittings. The baffled internal design employs gravity and surface tension to separate oil droplets from vapor, directing liquid back to the pan while allowing clean air to exit through the breathers. MOROSO's compact dimensions—10 x 7.3 x 12 inches—ensure versatile under-hood packaging without sacrificing capacity, and at 5.585 lbs, weight penalty remains minimal even on weight-critical builds.

This separator tank is ideal for owners of turbocharged, supercharged, or high-displacement engines where stock PCV systems fall short. Street racers, drift cars, and track-focused vehicles benefit most, but any serious performance build benefits from reduced oil carryover and improved engine cleanliness. Installation pairs seamlessly with catch-can setups and aftermarket intake systems; the 16 AN female connections accept industry-standard -16 fittings for quick, repeatable assembly. Verify clearance and breather line routing to your intake source before final installation.
