PQY Baffled Oil Catch Can Kit Universal 2 Port

The PQY 2-port oil catch can uses a compact body to save space in the engine bay. It features universal fitment designed for many cars, with a 50 micron bronze filter that helps separate oil particles from blow-by gas. This design defends critical components like the intercooler and intake system while aiding octane stability by reducing blow-by related detonation risks. Best for small to mid-sized engines with limited space, where a compact, easily serviceable can is preferred. A potential limitation is space in tight engine bays for both ports and routing hoses.
EVIL ENERGY Oil Catch Can Universal Baffled Kit

The EVIL ENERGY universal kit emphasizes versatility with a 300 ml capacity and a removable breather filter option. It includes a braided hose system and M16x1.5 ports, enabling flexible placement in many vehicle configurations. This kit is better for budget-conscious buyers seeking a straightforward, easy-to-install solution. Choose this if you want a simple PCV integration with the option to add a breather filter for pre-PCV setups. A caveat is the smaller capacity, which may require more frequent draining on higher-mileage engines.
PQY Baffled Oil Catch Can Kit Universal 2 Port With Drain Valve

This PQY model adds a bottom drain valve, making maintenance quicker and cleaner. It retains the 50 micron bronze filter to separate oil from blow-by, helping protect the intercooler and intake components. Best for drivers who want hassle-free drainage and easy service life, especially in enclosed spaces where opening the can is less convenient. Limitations include its moderate capacity and potential need for frequent emptying on high-blow-by engines.
EVIL ENERGY Oil Catch Can With NBR Hose Kit

This EVIL ENERGY kit emphasizes a 300 ml capacity with an NBR hose kit, designed for wear and heat resistance. It uses a baffled design and provides a robust interface with M16x1.5 threaded ports for secure connections. Best for cars requiring durable hoses and a compact catch can that still offers reliable oil separation. Consider this option if you prioritize hose quality and long-term heat resistance; note that the 300 ml size means relatively frequent maintenance on higher-mileage engines.
RULLINE Universal 350ml Oil Catch Can

The RULLINE 350 ml can is built from high-quality 0046 aluminum, featuring TIG-welded construction and a gasketed seal to prevent leaks. It includes a convenient dipstick to measure oil levels without opening the can, which supports simple maintenance routines. Best for buyers who want a sturdier, slightly larger option with easy level checks. A potential limitation is its slightly larger footprint, which may affect space in tighter engine bays.
Buying Guide: Key Purchase Considerations
- Capacity and space: How much oil can you reasonably store, and is there room in your engine bay for the can and hoses?
- Fitment and ports: Do you need 2 ports or a single port, and are the thread specs (such as M16x1.5) compatible with your PCV system?
- Filtration level: Are you prioritizing a finer filter (e.g., 50 micron bronze) to better trap oil droplets and moisture?
- Hose quality: Is the hose material (NBR, braided, heat resistant) suitable for your engine heat and oil exposure?
- Maintenance and drain access: Do you prefer a drain valve or dipstick for easy draining and fluid checks?
- Installation considerations: Is there enough space for mounting, routing hoses, and ensuring no kinks or interference with belts and pulleys?
FAQ: Quick Buyer Answers
- What is a blow-by catch tank used for? — It traps oil mist from the PCV system to protect the intake and intercooler from buildup.
- What capacity is typical for daily drivers? — Many compact kits range from 300 ml to 350 ml, balancing space and maintenance needs.
- Do all catch cans need a breather filter? — No; some setups use a sealed configuration, while others include an optional breather filter for pre-PCV applications.
- Which material is best for durability? — Aluminum bodies with TIG welding offer strong, lightweight construction and corrosion resistance.
- How often should I drain the can? — Drain as needed based on drive conditions, oil consumption, and can capacity.
- Can I install a catch can on most cars? — Yes, most cars support universal fitment, but verify space, hose routing, and thread sizes first.
