EVIL ENERGY 300ML Baffled Oil Catch Can — Universal Aluminum Breather Tank with 5ft NBR Hose

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

Designed as a compact, serviceable solution for PCV and crankcase ventilation plumbing, this EVIL ENERGY catch can uses a removable baffle (and optional steel wool) to condense and collect oil before it reaches the intake tract. The kit arrives with a durable 5 ft NBR hose and M16x1.5 threaded ports, making it adaptable to many petrol and light-duty diesel engines where space allows. It’s built for routine maintenance access and engineered to limit carbon and sludge transfer that shortens component life.

How does the baffled design reduce oil contamination?

The internal baffle disrupts vapor flow so heavier oil droplets and moisture condense and fall out of the airflow instead of traveling into the intake. Removing the baffle and adding steel wool increases surface area and improves separation for finer aerosol capture. Collected liquid remains accessible for periodic draining, preventing re-entrainment.

• Removable internal baffle for staged separation
• Option to add steel wool to increase capture efficiency
• Condensed oil drains to the can for easy maintenance

Will this catch can fit my vehicle and PCV setup?

The 300 ml capacity and threaded M16x1.5 inlet/outlet are compatible with many aftermarket or factory PCV plumbing layouts; however, confirm physical clearance and hose routing before purchase. For cars without a separate breather, install with the included breather filter; for vehicles with a PCV valve, use inline between PCV hoses as a sealed separator.

• 300 ml volume suits most compact installations
• Universal 3/8" ID hose and M16x1.5 thread connections
• Can be used as vented or sealed depending on application

What materials and hose specifications are included?

The canister is made from aluminum for light weight and corrosion resistance while the kit includes a 5 ft (1.5 m) NBR hose noted for heat and wear resistance. Hose inner diameter is 3/8" with a 5/8" outer diameter; these dimensions match many common PCV fittings to reduce the need for adapters.

• Aluminum body for durability and light weight
• NBR hose: 5 ft length, 3/8" ID, 5/8" OD for flexible routing
• M16x1.5 threaded ports for secure attachment

How should it be maintained, and are there cold-weather considerations?

Empty and inspect the catch can on a regular schedule to prevent overflow and blockages. In freezing climates, condensed moisture may freeze inside the system; clean the can weekly or revert to the stock PCV hose in severe cold to avoid vent restriction. Follow inspection intervals based on driving conditions and observed oil accumulation.

• Periodic draining and inspection recommended
• Weekly checks advised in below-freezing temperatures
• Temporary reinstatement of original PCV hose if freezing occurs

Who this product is for: The EVIL ENERGY 300ML baffled oil catch can is aimed at car enthusiasts, DIY mechanics, and everyday drivers who want a straightforward way to reduce oil and moisture entering their intake system. It suits vehicles with limited engine bay space that still need a fitted separation solution, and it’s ideal for anyone comfortable routing a 3/8" hose and performing periodic visual inspections and drains. If you need a compact, serviceable, and adaptable oil separator to lower intake contamination risk without complex plumbing, this catch can is a practical option.
