EVIL ENERGY 300ML Baffled Oil Catch Can — Universal Aluminium Breather Tank with 5ft 3/8" NBR Hose, Removable Baffle

EVIL ENERGY's 300ML baffled oil catch can is a compact, universal aluminum breather tank that captures oil and moisture from crankcase vapors to help keep intake systems cleaner.

This kit includes a 300ml baffled aluminum catch can with removable baffle and steel ball media, plus a 5ft (1.5m) 3/8" ID NBR hose and M16 x 1.5 fittings. Designed for universal fitment rather than a specific vehicle, the unit offers dual installation modes—use with the included breather filter for vent-to-atmosphere setups on pre-PCV engines, or install inline between PCV hoses as a sealed separator. The can’s internal baffling and optional media condense oil droplets, reducing carbon build-up on intake valves, throttle bodies and sensors when fitted correctly.

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

The EVIL ENERGY catch can slows crankcase vapors and forces them through baffling and optional steel-ball media. Oil droplets and moisture condense inside the can, leaving cleaner vapors to be routed back to the intake or vented safely.

• Removable baffle plus steel-ball media improves separation efficiency.
• Aluminum body resists corrosion and dissipates heat.
• 300ml capacity provides compact capture without major space demands.
• Drainable design for routine removal of collected oil.

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

This catch can is a universal unit; it’s not vehicle-specific. Measure your current crankcase or PCV hose inner diameter and verify available mounting space before installing to ensure proper fit and function.

• Hose kit includes 5ft of NBR hose with 3/8" (ID) and 5/8" (OD) dimensions.
• Ports use M16 × 1.5 threads—confirm fittings match your hoses or adapters.
• Professional installation is recommended when routing or modifying PCV lines.
• Check clearance for the 300ml can and mounting bracket in your engine bay.

How do I maintain this oil catch can and avoid freezing issues?

Regular maintenance prevents clogging and preserves separation performance. In cold climates, condensation in the crank ventilation system can freeze; frequent draining or reinstalling the original PCV hose during extreme cold helps avoid blockages.

• Inspect and drain the can at regular intervals based on driving conditions.
• Clean or remove baffle and media periodically to restore flow.
• In freezing temperatures, monitor moisture buildup and increase service frequency.
• Follow manufacturer recommendations and seek professional help if unsure.

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

Yes—this design supports both vented and sealed configurations. Use the breather filter to vent to atmosphere on pre-PCV engines, or omit the breather and install the can inline between PCV hoses for a sealed recirculation setup.

• Breather-filtered setup: vents to atmosphere, suitable for non-PCV systems.
• Sealed inline setup: fits between PCV hoses to return cleaner vapors to intake.
• Choose configuration based on vehicle emission controls and local regulations.
• Adapters or different hose lengths may be required for specific engine layouts.

Who is this for: The EVIL ENERGY 300ML baffled oil catch can kit is aimed at DIY enthusiasts, tuners, and mechanics who want a compact, universal solution to reduce oil and moisture contamination in intake systems. It’s well suited for turbocharged or high-mileage engines where crankcase vapor management matters, provided you verify hose sizes, mounting space and local venting rules before installation. If you prefer professional fitment, a mechanic can ensure correct hose routing, secure fittings and compliance with emission regulations.
