EVIL ENERGY 300ml Baffled Oil Catch Can Kit — Blue Aluminum PCV Air-Oil Separator with NBR Hose, M16*1.5 Ports

EVIL ENERGY's 300ml baffled oil catch can is a universal PCV air-oil separator designed to trap oil and moisture before they re-enter the intake, protecting engine components from buildup. This aluminum catch can kit includes a removable baffle, NBR fuel hose, and M16*1.5 threaded ports to fit most vehicles with space for installation. Its 300ml capacity and compact footprint make it suitable for a wide range of passenger cars and light trucks; install it as a vented breather or inline with the PCV depending on your engine setup. The kit ships in blue and is built for durability and straightforward maintenance.

How does the baffled design reduce carbon and sludge buildup?

The internal removable baffle slows crankcase vapors, causing oil droplets and moisture to coalesce and fall out of the airflow so they collect in the can. You can add a small amount of steel wool to the baffle area to improve condensation and capture efficiency.

• Removable baffle to separate oil from blow-by vapors
• Optional steel-wool packing increases condensation surface area
• Collected liquids remain in the 300ml reservoir for easy draining

Will this catch can fit my vehicle and how is it installed?

The EVIL ENERGY kit is built as a universal fit but requires available space near the PCV system. Ports use M16*1.5 threads and the included NBR hose measures 0.8m (2.6ft) long with a 3/8" ID to 2/3" OD, suitable for many OE vacuum lines.

• 300ml aluminum tank sized for most passenger vehicles
• M16*1.5 inlet/outlet threaded ports for secure hose fittings
• 0.8m NBR hose included—check routing, clearances, and mounting points before purchase

Can I use it with or without the breather filter and what are the differences?

You can configure the catch can as a vented breather or install it inline with the PCV hose depending on engine ventilation needs. Use the breather filter for pre-PCV or atmospheric venting setups; for closed-loop PCV systems, run the can inline without the breather to keep the system sealed.

• With breather: vents crankcase to atmosphere while capturing oil and moisture
• Inline (no breather): sits between PCV and intake to maintain closed-loop operation
• Choose the configuration that matches your vehicle's ventilation architecture

What maintenance or seasonal care does this catch can need?

Routine inspection and draining keep the catch can effective. In cold climates, condensation in the crank vent can freeze and clog lines—clean the can more frequently or revert to factory PCV routing during extreme cold to avoid blockages.

• Empty the 300ml reservoir regularly based on driving style and oil consumption
• Weekly checks recommended in freezing temperatures to prevent ice buildup
• Remove and clean the baffle and steel wool packing periodically for best performance

Who is this for? This EVIL ENERGY catch can is aimed at drivers who want to reduce oil and moisture recirculation into the intake—car enthusiasts, owners of higher-mileage engines, and anyone performing routine engine maintenance. It's well suited for DIY installers comfortable routing vacuum lines and securing a compact tank in the engine bay. If you need a universal, serviceable solution with clear installation options (vented or inline) and durable NBR hosework, this kit provides a practical, low-cost way to isolate crankcase contaminants from the intake system. If you have limited under-hood space or very cold-weather operation, verify fitment and local conditions before installing.

FAQ

Q: How often should I empty the EVIL ENERGY 300ml catch can?

A: Empty it when the reservoir reaches near capacity or during routine service—frequency varies by driving conditions and engine oil consumption.

Q: Can I use the catch can on a turbocharged engine?

A: Yes, it can be used on turbocharged engines; confirm hose routing, clearances, and that the installation preserves required vacuum lines.
