EVIL ENERGY 300ml Baffled Oil Catch Can Kit – Aluminum Air-Oil Separator, Sealed or Vented with Breather Filter

EVIL ENERGY's 300ml baffled oil catch can is an aluminum air-oil separator designed to trap crankcase oil and moisture before they re-enter the intake, helping keep your PCV system and intake tract cleaner.

This compact, universal kit fits most gasoline engines and gives you the option to run it as a sealed in-line can or as a vented breather using the included filter. Constructed from lightweight aluminum and fitted with NBR hoses and M16x1.5 inlet/outlet threads, it holds 300 ml of collected oil and uses internal baffling to separate oil from blow-by gases. Whether you want to protect turbochargers, extend intake cleanliness, or simply reduce carbon buildup, this kit offers a straightforward installation with flexible routing choices.

How does the baffled design improve oil separation?

The internal baffle slows and redirects incoming crankcase vapors so heavier oil droplets fall out of the flow and collect on the can walls. This reduces the volume of oil that reaches the intake or the turbocharger, helping maintain performance and reducing deposits. Baffling also reduces foaming and keeps oil trapped under different driving conditions.

• Internal baffle chamber for improved droplet knock-out
• 300 ml capacity to collect extended amounts before service
• Aluminum body dissipates heat and resists corrosion

Can I use it with or without the breather filter?

Yes — the kit ships to support both setups. Use the breather filter when venting to atmosphere (common for non-PCV setups) or remove it and plumb inline between PCV hoses for a sealed system that routes filtered gases back into the intake. This flexibility suits a range of factory and modified valve-train layouts.

• Vented option: fit the breather filter for open-air breathing
• Sealed option: connect both PCV hoses inline to recirculate gases
• Adapters and hoses included for most common routing needs

Will it fit my car and how complicated is installation?

The EVIL ENERGY catch can is designed as a universal unit and works with most vehicles that have space for mounting. Hose length is approximately 0.8 m (2.6 ft) with 3/8" ID and M16x1.5 in/out threads, so verify clearance and thread compatibility before fitting. Installation is typically a simple swap into the PCV line or a short run to a convenient mounting point near the engine bay.

• Hose spec: 0.8 m length, 3/8" ID, 2/3" OD
• Thread spec: inlet/outlet M16 x 1.5
• Mount and service weekly in cold climates to avoid moisture freezing

How do I maintain and service the catch can?

Drain and wipe out the can whenever the collected oil level approaches the 300 ml capacity or as part of routine oil-change intervals. In freezing conditions, check and empty more often because moisture can accumulate and freeze inside hoses or fittings. The aluminum body and simple hose connections make cleaning quick with minimal tools.

• Empty before the 300 ml limit is reached to prevent overflow
• Weekly inspections recommended at or below freezing temperatures
• Clean with solvent and dry before reassembling the breather filter

Who is this for? The EVIL ENERGY 300ml baffled oil catch can kit is suited for DIY-minded drivers, enthusiast tuners, and owners of turbocharged or high-mileage petrol engines who want to reduce oil carryover into the intake. It’s ideal if you need a compact, universal solution that can be run vented or sealed, offers straightforward installation, and provides reliable separation without complicated electronics or vehicle-specific adapters. Verify hose and thread compatibility with your engine before purchase, and plan regular inspections in cold climates to prevent moisture-related issues.
