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

EVIL ENERGY's 300ML baffled oil catch can is a compact aluminum air-oil separator that traps blow-by oil and moisture before they reach the intake, letting you run a cleaner PCV system or sealed setup.

This universal oil catch can kit is designed for hobbyists and professional installers who want a simple way to reduce oil contamination in the intake tract. Built from lightweight aluminum with a removable internal baffle and optional breather filter, the can captures oil droplets and water vapor while offering installation flexibility: vent-to-atmosphere for pre-PCV engines or inline as a sealed catch can for PCV-equipped units. The kit includes a durable 5 ft NBR hose (3/8" ID) and M16x1.5 threaded ports for secure fittings.

How does the baffled design protect the engine?

The internal removable baffle and the ability to add steel shot increase dwell time and promote oil separation from the crankcase gases. That means fewer oily vapors reach intake valves and combustion chambers, reducing deposits over time without altering normal crankcase ventilation.

• Removable baffle for easy cleaning
• Steel-ball option to improve oil coalescence
• 300 mL capacity suitable for many street engines
• Aluminum body resists corrosion and heat

Should I use the breather filter or run it inline with PCV hoses?

The kit supports both configurations: install the included breather filter for venting to atmosphere on pre-PCV systems, or remove the breather and plumb the can inline between PCV hoses for a sealed setup. Choose based on your vehicle’s emission and ventilation requirements.

• Breather filter: for engines that originally vent to atmosphere
• Inline (sealed) setup: for PCV systems to prevent vapor escape
• Threaded M16x1.5 ports for secure connections
• Professional installation recommended for correct routing

Will this fit my car and how do I install it?

This is a universal 300 mL catch can—fit depends on hose inner diameter, available mounting space, and routing. Measure your existing hose ID and compare to the kit’s 3/8" (0.375") inner diameter; check clearance where you plan to mount the can and ensure the M16x1.5 fittings match your adapters or hose clamps.

• Hose included: 5 ft (1.5 m) NBR hose, ID 3/8", OD 5/8"
• Ports: M16x1.5 thread for inlet/outlet fittings
• Verify mounting location and hose routing before purchase
• Consider professional installation if unsure

How do I maintain it and avoid freeze-related problems?

Drain and clean the catch can regularly to prevent sludge buildup, especially in wet climates where crankcase moisture increases. In freezing temperatures the vented moisture can freeze and block flow, so either clean more frequently or revert to the original PCV hose when conditions risk ice formation.

• Empty catch can at recommended service intervals
• Clean baffle and filter as needed to maintain flow
• Reinstall OEM PCV hose in extreme cold to prevent icing
• Inspect hoses and clamps for wear and secure fit

Who is this for: The EVIL ENERGY 300ML baffled oil catch can is aimed at car owners, tuners, and mechanics who want a compact, flexible solution to reduce oil contamination in the intake system. It's well suited for street and light performance vehicles where space is limited, and for anyone who can verify hose sizes and feels comfortable with or can arrange professional installation. If you need a larger capacity or a vehicle-specific kit, confirm fitment or look at other sizes before ordering.
