EVIL ENERGY 300ml Baffled Oil Catch Can Kit with Detachable Breather Filter, M16x1.5 Threads

EVIL ENERGY's 300ml baffled oil catch can kit captures crankcase oil and vapors before they re-enter the intake, offering a tunable venting option with a detachable breather filter.

This compact, universal catch can is designed to fit many gasoline engines as an aftermarket crankcase ventilation accessory. With a 300ml capacity, M16x1.5 inlet/outlet threads, and a baffled internal design, it separates oil mist from blow-by gases and stores condensate for periodic draining. The kit includes a 0.8m (2.6ft) hose with 3/8" inner diameter and provides the option to run the can as a sealed inline unit for PCV systems or as a vented unit using the supplied breather filter for pre-PCV setups.

How does the EVIL ENERGY catch can reduce oil in the intake?

The baffled interior slows incoming crankcase gases so oil droplets coalesce and run down into the reservoir instead of traveling into the intake tract. Removing that oil-laden vapor helps keep intake valves and intake tract surfaces cleaner over time. It doesn’t change factory PCV behavior when installed inline; instead, it intercepts and stores contaminants before they reach the intake.

• Baffled core design increases separation efficiency.
• 300ml reservoir holds condensate between service intervals.
• Detachable breather option lets you vent to atmosphere on pre-PCV engines.
• Inline installation available for sealed PCV systems.

Will this catch can fit my vehicle and what do I need to check?

This unit is universal but not one-size-fits-all: confirm hose inner diameter, thread type, and mounting space before purchasing. The kit uses M16x1.5 inlet/outlet threads and a 3/8" (ID) hose; measure your existing PCV hose and available clearance to ensure correct fitment. Professional installation is recommended if you are unfamiliar with PCV plumbing.

• Hose length included: 0.8m (2.6ft); hose ID: 3/8", OD: 2/3".
• Thread spec: M16 x 1.5 for inlet and outlet fittings.
• Check mounting locations for clearance and bracket placement.
• Consider adapters if your vehicle uses different thread sizes.

How should I install and maintain the EVIL ENERGY catch can?

Install either inline between PCV hoses for a sealed system or fit the breather filter for atmospheric venting on pre-PCV engines. Secure the unit with a bracket in a stable location away from extreme heat and road spray. Regular inspection and draining are important: remove accumulated oil and grime when the reservoir is near capacity or according to your driving conditions.

• Install inline for sealed PCV engines or with breather filter for venting.
• Mount with included hardware in a protected, accessible spot.
• Drain and clean weekly in extremely cold or wet climates to avoid freezing risk.
• Reinstall original PCV hose if excessive moisture or freezing occurs.

What are the practical limits and cautions I should know?

The can helps trap oil and moisture but isn’t a maintenance-free cure: capacity is limited to 300ml and must be emptied periodically. In regions where temperatures reach freezing or lower, condensed moisture can increase and risk freezing in the crank vent—frequent cleaning or temporarily returning to the OEM PCV routing may be necessary. Always verify hose diameters and thread sizes to avoid improper fitment.

• Capacity: 300ml — monitor fill level frequently under heavy-duty conditions.
• Freezing temperatures increase moisture collection—clean more often.
• Not vehicle-specific; verify hose and thread compatibility before purchase.
• Professional installation recommended for correct routing and sealing.

Who is this for: The EVIL ENERGY 300ml baffled catch can kit suits enthusiasts and DIY mechanics who want an affordable aftermarket solution to reduce oil and moisture entering the intake—especially on older engines without factory breathers or on modified cars where intake cleanliness matters. Choose this kit if your vehicle accepts M16x1.5 fittings, you can accommodate a 0.8m hose run, and you’re willing to check and drain the can periodically as part of routine maintenance.
