BBK Performance Billet Aluminum PCV Oil Separator Catch Can Kit

The BBK Performance Oil Separator Kit is a precision-engineered catch can system designed to intercept harmful oil vapor from your engine's PCV (Positive Crankcase Ventilation) system before it reaches the intake tract and combustion chamber. Built on proven BBK technology and premium materials, every kit in this line delivers the same real-world performance protection across a wide range of applications.

How It Works

During normal engine operation, crankcase pressure is vented through the PCV valve back into the intake manifold. Over time, oil vapor carried in this airflow coats intake valves and burns inside the combustion chamber, leading to carbon buildup that robs power and reduces fuel economy. Excess oil in the combustion charge can also dilute effective octane levels, increasing the risk of detonation — a particularly common concern in modern high-compression engines. The BBK Oil Separator catches this vapor before it causes damage, depositing captured oil into a removable reservoir rather than allowing it to recycle back through the engine.

Key Features:

• CNC-machined billet aluminum construction — machined from solid billet aluminum for strength, precision, and a premium underhood appearance
• Anodized finish for lasting corrosion resistance and clean aesthetics
• High-efficiency, multi-stage filtration captures fine oil vapor droplets, ensuring only clean, oil-free air enters the intake
• Knurled removable base with O-ring seal for leak-free, tool-free draining at every service interval
• Protects intake valves and combustion chambers from carbon buildup, preserving fuel economy and long-term engine performance
• Helps maintain proper octane levels to reduce the risk of detonation in high-compression and high-RPM applications
• Complete kits include factory-style PCV hoses, connectors, and all necessary hardware for a straightforward installation
• Application-specific and universal fitments available across a wide range of popular domestic platforms
