EVIL ENERGY 300ml Baffled Oil Catch Can Kit — Blue Aluminum Tank, NBR Hose, M16*1.5 Ports

EVIL ENERGY's 300ml baffled oil catch can is a universal aluminum air–oil separator designed to trap oil and moisture before they re-enter the intake, helping reduce carbon buildup in PCV systems.

This compact catch can kit pairs a removable-baffle aluminum tank with a durable NBR hose and M16*1.5 threaded ports to give you a simple, serviceable way to manage crankcase vapors. It fits many engines when the hose inner diameter and mounting space match; the kit includes a 0.8m fuel-rated hose and guidance for choosing the right configuration. Installation options allow it to be used either as a vented breather or inline with the PCV depending on your vehicle’s needs.

How does the baffled design reduce oil and moisture carryover?

The internal removable baffle creates a tortuous path that slows vapor flow, causing oil droplets and moisture to condense and collect away from the PCV line. Adding steel wool further increases surface area for capture. This separation lowers the amount of oil reaching the intake tract and valves without changing engine operation.

• Removable baffle for easy cleaning and inspection
• Optional steel wool placement to improve droplet capture
• 300ml capacity reduces frequent emptying while remaining compact

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

The EVIL ENERGY kit is universal but not one-size-fits-all; you must measure your existing PCV or breather hose inner diameter and verify mounting room. The included hose is NBR with 3/8" ID and 2/3" OD, and the kit uses M16*1.5 fittings. If measurements or fitting threads differ, select a different hose/fitting kit or consult a professional installer.

• Measure original hose inner diameter before ordering
• Verify available mounting space for the 300ml tank
• Use M16*1.5 ports or adapt with correct fittings if needed

Can I install the catch can as a vent or inline with the PCV?

Yes — the design supports both setups. Fit it with the breather filter as a vented catch can for pre-PCV or open-vent applications; install it inline between PCV hoses without the breather when you need a sealed system. Choose the configuration that matches your vehicle’s factory ventilation strategy.

• Vented setup: breather filter installed for crankcase venting
• Inline sealed setup: bypasses breather and connects between PCV hoses
• Follow vehicle ventilation type to avoid incorrect plumbing

What maintenance and cold-weather cautions should I follow?

The catch can collects oil and water, so routine draining and cleaning keeps it working properly; in freezing conditions moisture in the system can freeze and block passages. Check and clean the can weekly in subfreezing weather or reinstall the original PCV hose temporarily. The removable baffle makes inspection and cleaning straightforward.

• Empty and clean the can regularly, more often in cold climates
• Remove or inspect steel wool during service to prevent clogging
• Reinstall original hose in prolonged freezing to avoid blockages

Who is this for: EVIL ENERGY’s 300ml baffled oil catch can kit is intended for vehicle owners, tuners, and mechanics who want a compact, serviceable way to reduce oil carryover in PCV systems. It suits cars with compatible hose sizes and limited engine-bay space, and it works well for drivers who prefer a maintainable aluminum can with a replaceable hose and clear mounting options. If you’re unsure about fitment or thread sizes, have a professional check your setup before installation.
