EVIL ENERGY 300ML Baffled Oil Catch Can Kit — Aluminum Separator with Breather Filter & 5ft 3/8" NBR Hose

EVIL ENERGY's 300ML baffled oil catch can is a compact aluminum separator that captures oil, moisture, and blow-by vapors before they re-enter the intake, helping keep induction components cleaner.

This universal oil catch can kit includes a baffled 300ml aluminum tank, removable baffle and steel-ball dampening, a breather filter option for vented setups, and a 5-foot 3/8" ID NBR hose with M16x1.5 threaded fittings. Designed for retrofits and maintenance-minded owners, it reduces oily deposits in the intake tract and gives you a manageable collection point for condensate and blow-by. The can works as either a sealed inline unit for PCV systems or as a vented can with the included breather, so confirm hose diameters and mounting space before fitting. Professional installation is recommended for a clean, leak-free setup.

How does this catch can limit carbon and oil buildup in the intake?

The baffled interior plus removable baffle and added steel balls cause vapor and droplets to collide and coalesce, so oil and moisture fall out of the airstream and collect in the can. This reduces the amount of oily residue carried back into intake ports, throttle body, and valves.

• Baffle and steel-ball trap enhance droplet separation.
• 300ml collection volume for routine maintenance intervals.
• Aluminum body resists corrosion and handles under-hood heat.

Can I use this on cars with or without a PCV breather?

Yes — the kit is adaptable. Fit the breather filter to use the can as a vent on pre-PCV or non-sealed systems, or remove the breather and plumb the can inline between PCV hoses as a sealed separator for systems that require closed-loop operation.

• Vented setup: install included breather filter for atmosphere discharge.
• Sealed setup: install inline between PCV and intake for closed systems.
• Confirm hose routing and orientation to maintain proper crankcase ventilation.

What hose, fittings, and fitment checks should I make before buying?

This universal kit uses 3/8" ID (5/8" OD) NBR hose and M16x1.5 threaded ports. Measure your existing hose inner diameter and available mounting space, and compare thread/fitting types to ensure a secure connection. If your vehicle uses a different size or non-standard fittings, source compatible adapters or a different kit.

• Hose: 5 ft (1.5 m) length, 3/8" ID, high-wear NBR material.
• Ports: M16x1.5 thread for inlet and outlet fittings.
• Check for clearance and bracket mounting points before installation.

How should I maintain the catch can and handle cold-weather risks?

Empty and clean the catch can regularly to prevent overflow and inspect hoses for blockages. In freezing conditions more moisture can accumulate in the crank vent; consider reinstalling the stock PCV hose or cleaning the catch can weekly to avoid frozen blockages that could affect ventilation.

• Inspect and drain the 300ml reservoir on a scheduled basis.
• Clean baffle and internal components during service intervals.
• Revert to stock routing in severe cold if moisture freeze is a concern.

Who is this for: EVIL ENERGY's 300ml baffled oil catch can kit is aimed at DIY mechanics, performance enthusiasts, and maintenance-focused vehicle owners who want to reduce oily deposits in the intake tract and protect throttle bodies, EGR passages, and intake valves. It's suitable for many aftermarket and older vehicles where hose sizes match 3/8" ID, and for anyone comfortable verifying fitment or arranging professional installation. If you need a larger capacity, different hose size, or factory-specific fittings, consider a model tailored to your vehicle's specifications.
