EVIL ENERGY 300ML Baffled Oil Catch Can – Aluminum Universal Oil Separator with 5ft 3/8" NBR Hose, Removable Baffle

EVIL ENERGY's 300ML baffled oil catch can is a compact aluminum breather tank that traps oil and moisture before they contaminate your intake, helping keep valves and pistons cleaner.

Designed as a universal add-on for gasoline engines, this 300ml oil separator uses a removable baffle and optional steel-ball media to condense and collect blow-by oil and water vapor from crankcase vents. It ships with a 5-foot NBR hose (3/8" ID) and M16*1.5 threaded ports for secure connections, offering a robust, heat-resistant route to reduce carbon deposits in the intake tract when fitted correctly.

How does the baffled design reduce intake contamination?

The internal removable baffle slows airflow so oil droplets and moisture coalesce and fall out of the vapor stream. Adding the included steel balls increases surface area for condensation, improving separation efficiency without restricting crankcase ventilation.

• Removable internal baffle for staged airflow and easy cleaning
• Steel-ball media option to boost droplet capture
• Aluminum body resists corrosion and handles engine bay heat

Will this fit my vehicle and how do I mount it?

With a 300ml capacity and standard threaded ports, the EVIL ENERGY catch can fits most cars and light trucks if there is adequate space for installation. It’s intended for inline connection to PCV hoses or as a vent-to-atmosphere setup when used with the breather filter.

• Universal sizing—300ml volume works for many engines
• M16*1.5 threaded inlet/outlet for common fittings
• Includes 5ft (1.5m) NBR hose (3/8" ID, 5/8" OD) for flexible routing

How should I use it with or without a breather filter?

Install the can with its breather filter for pre-PCV or naturally ventilated engines to vent to atmosphere while still capturing oil. For engines with an active PCV system, plumb the can inline between PCV hoses and omit the breather filter so the system remains sealed and functional.

• Breather-filter mode: vent with filtration for non-PCV setups
• Inline mode: connect between PCV hoses to keep system sealed
• Choose hose routing to avoid heat sources and kinks

What maintenance is required and are there cold-weather considerations?

Empty and clean the catch can regularly to prevent build-up—weekly checks are advisable in high-moisture or cold conditions. In freezing environments, accumulated moisture can freeze and obstruct venting; if that’s a concern, revert to the original PCV hose during extreme cold or increase service frequency.

• Easy-to-remove top for draining and access to the baffle
• Recommended frequent inspection in winter to prevent freezing
• Wash and replace steel balls or baffle as needed to maintain performance

Who is this for? Drivers who want a simple, serviceable way to reduce oil carryover into the intake—particularly enthusiasts running older cars, turbocharged engines, or anyone aiming to slow carbon buildup—will value the EVIL ENERGY 300ML catch can. It’s suited to DIY installers who can accommodate a compact canister and routing for a 3/8" hose, and who understand the difference between sealed PCV setups and vented configurations. EVIL ENERGY backs this product with straightforward after-sales support for returns or exchanges if you encounter quality issues.
