EVIL ENERGY Universal Baffled Catch Can with Breather Filter
Brand: EVIL ENERGY
A reliable, budget-friendly catch can that offers flexible installation options for most vehicles.
This EVIL ENERGY kit is a versatile choice for most cars, thanks to its universal design and 300ml capacity. The included breather filter gives you flexibility: install it for pre-PCV cars as a vent system, or remove it for an inline sealed setup. The 2.6ft NBR hose with 3/8-inch ID fits standard PCV connections, and the M16*1.5 threads are common on many vehicles.
One thing to keep in mind is the note about freezing temperatures. In cold climates, the crank vent system produces more moisture, which could freeze inside the can. If you live in a colder region, you might need to check and drain it more frequently. Otherwise, this is a solid, affordable option for basic oil separation.
- Flexible breather filter option
- Universal fit for most cars
- Affordable price point
- Freezing risk in cold climates
- Short hose length

Buyer’s Guide: What to Consider
Choosing the right catch can involves understanding your vehicle’s PCV system and your driving needs. Here are five key factors to consider before making a purchase.
- Baffled vs. Non-Baffled: Baffled catch cans use internal baffles or filters to separate oil from air more effectively, reducing the chance of oil being sucked back into the intake. Non-baffled cans are simpler but less efficient. For most engines, a baffled design is recommended to prevent carbon buildup.
- Capacity: Catch can capacity determines how often you need to empty it. A 300ml can is fine for daily driving, but if you track your car or drive aggressively, a larger capacity like 750ml reduces maintenance frequency. Consider your driving habits when choosing.
- Hose Length and ID: Hose length affects where you can mount the can. A longer hose (5ft) offers more flexibility, while a shorter one (2.6ft) may limit placement. The inner diameter (ID) must match your PCV system's hose size, typically 3/8-inch, to ensure a proper seal.
- Breather Filter: Some catch cans come with a breather filter for vented installations on pre-PCV cars. This allows the crankcase to breathe while still catching oil. If your car doesn't have a PCV valve, a breather filter is essential. Others can be installed inline without it.
- Build Material and Sealing: Aluminum alloy is common for its durability and heat resistance. Look for fully welded construction and quality O-ring seals to prevent leaks. Anodized finishes add corrosion resistance. A well-sealed can ensures no oil vapors escape into the engine bay.
Conclusion
In summary, a catch can kit is a smart investment for any engine, especially direct-injection models prone to carbon buildup. The options above range from budget-friendly universal kits to high-capacity performance cans, so there’s something for every driver.
For most daily drivers, the EVIL ENERGY baffled cans with breather filters offer excellent value and reliability. If you need extra capacity or advanced filtration, consider the 10AN model or the bronze filter version. Whichever you choose, regular maintenance will keep your engine clean and running efficiently.
