EVIL ENERGY 300ML Baffled Oil Catch Can with Breather Filter — Universal Aluminium, 5ft Hose

EVIL ENERGY’s 300ML baffled oil catch can is a universal aluminum crankcase oil separator with a removable baffle and breather filter to trap oil and moisture before they reach the intake.

This compact 300ml catch can kit is built for tuners and everyday drivers who want to reduce oil vapor and moisture from entering the intake and PCV system. Machined from aluminum with M16x1.5 inlet/outlet threads and a 5ft NBR hose included, the assembly is designed to fit many engine bays as either a vented breather or an inline seal can. It’s a practical add-on for engines prone to carbon buildup or for vehicles where extra crankcase vapor control is desired.

How does the baffled design improve oil separation?

The removable baffle inside the EVIL ENERGY catch can slows airflow and increases surface area, letting oil droplets coalesce and fall out of the airstream. Adding the supplied steel balls further encourages droplets to collide and separate, reducing the amount of oil and moisture that returns to the intake.

• Removable internal baffle for staged separation
• Optional steel-ball media to enhance droplet capture
• Clear bottom or drain port allows periodic removal of trapped oil

Can I use this catch can with my vehicle’s PCV system?

Yes — the EVIL ENERGY unit is configurable for both pre-PCV setups and inline PCV systems. Install the breather filter when you need an open vent, or run it without the filter inline between PCV hoses to act as a sealed separator.

• Use breather filter for open venting on non-PCV or vented systems
• Use sealed inline configuration for PCV-equipped engines
• M16x1.5 ports match many fittings; verify hose ID before installing

What fittings and hose dimensions are included, and how do I check compatibility?

The kit ships with a 5ft (1.5m) NBR hose with a 3/8" inner diameter and a 5/8" outer diameter, chosen for heat and wear resistance. Before purchasing, measure your factory hose inner diameter and confirm available mounting space to make sure the 300ml can and hose routing will fit your engine bay.

• Hose: 5ft length, 3/8" ID, 5/8" OD (NBR material)
• Ports: M16x1.5 thread for secure fittings
• Recommended: measure existing hose ID and verify clearance

How should I maintain the catch can in different weather conditions?

Because crank ventilation can generate more moisture in cold weather, the catch can can collect water and oil that may freeze if neglected. Empty or inspect the can weekly in freezing conditions and reinstall the original PCV hose if extreme cold risks causing blockages.

• Weekly inspection and drain recommended in sub-freezing temperatures
• Remove breather filter or reinstall stock PCV routing for winter use
• Professional installation advised for correct hose routing and mounting

Who is this for? Enthusiasts, tuners, and daily drivers who want a compact, durable solution to reduce oil vapor and moisture recirculation will find this EVIL ENERGY 300ML baffled catch can useful. It’s especially suited for older engines showing early carbon or oil-fouling symptoms, turbocharged engines sensitive to intake contamination, and anyone who wants a configurable vented or sealed crankcase separator with a quality NBR hose included.
