EVIL ENERGY Oil Catch Can 300ml Baffled Aluminium Universal Kit with 5ft NBR Hose

EVIL ENERGY's 300ML baffled oil catch can is a compact aluminum breather tank that separates oil and moisture from crankcase vapors to reduce intake contamination. This universal kit includes a 300ml baffled aluminum canister, a removable internal baffle (and the option to add steel wool), and a 5ft NBR hose with 3/8" inner diameter so you can route crankcase ventilation away from the intake system. The catch can is provided with M16x1.5 threaded ports and can be fitted with or without a breather cap depending on whether your vehicle vents to atmosphere or into the PCV system. The design aims to trap oil droplets and moisture before they reach intake valves and throttle bodies, helping maintain cleaner intake pathways.

How does this catch can reduce oil and moisture entering the intake?

The baffled interior forces vapors to change direction and condense, while optional steel wool or the removable baffle captures oil droplets. Condensed oil collects inside the 300ml reservoir for periodic drainage instead of traveling into the intake tract.

• Baffled chamber slows airflow and promotes condensation
• Optional steel wool increases surface area for oil capture
• Aluminum body resists corrosion and sheds heat for better condensation
• 300ml capacity balances compact size with useful collection volume

Will this kit fit my vehicle and how do I choose the right hose size?

The EVIL ENERGY catch can is universal, but correct fitment depends on your engine’s hose inner diameter and available mounting space. Measure your existing crankcase or PCV hose inner diameter, verify that M16x1.5 fittings will work with your setup, and confirm there is room to mount a 300ml canister. Professional installation is recommended if you’re unsure.

• Hose supplied: NBR, 5ft (1.5m) length, 3/8" ID, 5/8" OD
• Ports: M16x1.5 thread for inlet/outlet fittings
• Check clearance for placement and hose routing before installing
• Optional professional install advised for tight engine bays

Can I use the catch can with or without the breather filter?

Yes — install it with the supplied breather cap if you want the unit to vent to atmosphere (pre-PCV style) or run it inline without the breather when connecting between PCV hoses. Choose the configuration that matches your vehicle’s ventilation design and local regulations regarding crankcase emissions.

• Breather-on: vents filtered air to atmosphere for non-PCV setups
• Inline: connects between PCV hoses to seal and trap oil in closed systems
• Swap options quickly using the threaded ports
• Follow local laws on venting to atmosphere versus recirculation

What maintenance does the EVIL ENERGY catch can require?

Drain and inspect the can regularly — frequency depends on driving conditions and engine blow-by levels. In cold climates, increased moisture can freeze, so weekly checks or temporarily reverting to the factory PCV hose in extreme cold are recommended to avoid blockage.

• Empty collected oil periodically based on accumulation
• Clean the baffle and internal surfaces during service intervals
• In freezing conditions, inspect weekly or reinstall OEM hose as needed
• Replace NBR hose if cracked or hardened over time

Who is this for? This EVIL ENERGY 300ML baffled oil catch can is aimed at DIY enthusiasts, tuners, and vehicle owners who want a compact, universal solution to limit intake contamination from crankcase vapors. It's suitable for naturally aspirated and forced-induction engines where space is limited and a moderate collection capacity is desired. If you have a known blow-by issue, frequently track your car, or are converting a pre-PCV setup, this kit offers an accessible way to capture oil and moisture before it reaches intake components. For exact fitment and optimal performance, measure hose sizes and consider professional installation when in doubt.

FAQ

Q: How do I know if the 3/8" hose fits my car?

A: Measure your existing crankcase or PCV hose inner diameter; if it’s 3/8" this kit fits. Check clearance and M16x1.5 fitting compatibility before installing.

Q: How often should I empty the catch can?

A: Empty when oil accumulation is noticeable; typical intervals range from weeks to months depending on engine condition and driving style.
