EVIL ENERGY Oil Catch Can 300ml Baffled Kit with Breather Filter — Compact, Serviceable PCV Trap

The EVIL ENERGY 300ml baffled oil catch can kit reduces oil and moisture re-entry into the intake by trapping blow-by contaminants before they reach the engine.

This compact, vehicle-agnostic catch can is built for hobbyists and mechanics who want a simple way to limit oil vapor, moisture and particulate carryover from the crankcase ventilation system. The kit includes a 300ml baffled reservoir, an optional breather filter for non-PCV setups, and hoses and fittings sized for commonly used PCV connections. It’s designed to be mounted in tight engine bays and provides a serviceable solution: empty and clean it regularly to maintain performance, especially in cold climates where moisture can accumulate.

How does this catch can fit my vehicle?

The EVIL ENERGY unit is a universal design intended to work across many applications, not a vehicle-specific part. Before purchasing, check the inner diameter of your existing hoses and confirm any threaded fitting requirements to ensure compatibility.

• Hose specifications: 2.6 ft (0.8 m) length, 3/8" inner diameter, 2/3" outer diameter
• Thread size for inlet/outlet: M16 x 1.5
• Mounting: measure available engine bay space for secure installation
• Professional installation recommended for best routing and sealing

Why is the baffled design important?

The internal baffle slows airflow and captures oil droplets and heavier contaminants before they can be carried back into the intake tract. This reduces the amount of oil and residue that sticks to intake valves and intercoolers, helping to keep intake components cleaner between maintenance intervals.

• Baffles promote condensation and droplet separation for more effective trapping
• 300ml capacity balances space and service interval frequency
• Serviceable design: remove, drain and clean as part of routine maintenance

When should I use the breather filter versus inline PCV installation?

The kit offers flexibility: fit the breather filter when your vehicle lacks a closed PCV system and you need an open vent, or install the catch can inline between PCV hoses to act as a sealed trap in closed systems. Choose based on your vehicle’s ventilation architecture and local regulations.

• Breather filter option: for pre-PCV or open-vent setups requiring atmospheric venting
• Inline sealer option: place between PCV hoses for closed-system routes
• Swap configurations as needed for seasonal or vehicle changes

How should I maintain this catch can, especially in cold weather?

Cold conditions increase moisture in the crankcase ventilation stream, which can lead to freezing if the can is neglected. Empty and inspect the can frequently during winter, and reinstall the vehicle’s original PCV hose if ice risk is high.

• Weekly checks recommended when temperatures reach freezing or below
• Drain and clean the 300ml reservoir to prevent sludge and ice buildup
• Reinstall original PCV hose or use inline routing if persistent condensation occurs

Who is this for: The EVIL ENERGY 300ml baffled catch can kit is aimed at enthusiast drivers, tuners and DIY mechanics who want a compact, adaptable solution to reduce oil and moisture carryover in their engine’s ventilation system. It’s best suited to users who can verify hose sizes and mounting space beforehand and who will perform routine service. If you’re looking for a straightforward, reversible upgrade to help keep intake components cleaner between services, this kit offers a practical balance of size, flexibility and serviceability.
