This dual-layer filtering mechanism is crucial as it prevents harmful contaminants from entering the intake manifold, which can be detrimental to engine performance. I find this feature particularly appealing as it ensures that my engine remains clean and operates efficiently.

Moreover, the reusable design is a game-changer. With the inclusion of a drain valve, I can easily empty the contents of the catch can without having to reinstall it. This convenience means less downtime for my vehicle and more time enjoying the open road. The ability to reuse the catch can consistently is not only practical but also cost-effective in the long run, which makes me feel like I’m making a smart investment.

Keeping my engine clean is paramount, and the WENJTP Oil Catch Can excels in this area.

It’s also worth noting that WENJTP has made improvements to the sealing of the catch can by switching to a tapered thread and adding thread seal tape. This enhancement ensures that there are fewer leaks, which is essential for the proper functioning of any catch can. While the adapters may not fully enter the oil catch can as depicted in some pictures, this minor discrepancy doesn’t diminish the product’s overall effectiveness.

2. EVIL ENERGY Oil Catch Can, Universal Baffled Catch Can Kit with Breather Filter, 300ml Aluminum Air Oil Separator Tank NBR Fuel Hose Kits for PCV System

As I dive into the world of automotive accessories, one product that stands out to me is the EVIL ENERGY Oil Catch Can. This universal baffled catch can kit is designed for anyone looking to enhance the performance and longevity of their vehicle’s engine. With its 300ml aluminum air oil separator tank and NBR fuel hose kits for the PCV system, this product promises a lot. But what does this mean for car enthusiasts and everyday drivers alike? Let’s break it down.

First off, the universality of this oil catch can is a major plus. It can be applied to most cars, which means whether you drive a sedan, a truck, or a sporty coupe, this catch can is likely to fit your needs. The installation process is straightforward, provided there’s sufficient space in your engine bay. This feature is especially beneficial for individuals who enjoy customizing their cars or enhancing engine performance without needing to buy a specific kit for their model.

The specifications of the catch can are also impressive. With a hose length of 2.6ft (0.8m) and an internal diameter of 3/8″, the design allows for flexibility during installation. The capacity of 300ml is significant enough to collect excess oil and moisture, thus preventing them from re-entering the engine. This is crucial for maintaining optimal engine health, as the build-up of oil vapor can lead to performance issues over time.

Another remarkable feature is the Breather Filter option. For those with pre-PCV (Positive Crankcase Ventilation) systems, installing the oil catch can with a breather filter allows for a vent system, which can enhance engine performance by reducing pressure build-up. Alternatively, it can be installed in line between PCV hoses without the breather filter, serving as a seal can. This flexibility caters to different preferences and vehicle setups, making it a versatile choice for users.

However, I must note a critical aspect regarding maintenance. When the temperature drops to freezing levels, the crank vent system may generate a significant amount of moisture. This can present a risk of freezing, which is why it’s advised to clean the oil catch can weekly or revert to the original PCV hose. This proactive maintenance ensures that the catch can functions effectively and protects your engine from potential issues.

The after-sales service provided by EVIL ENERGY is commendable. They stand by the quality of their product, offering hassle-free returns or exchanges in case of quality issues. This commitment to customer satisfaction is refreshing and provides peace of mind for anyone considering a purchase. Plus, their customer service team is readily available to assist with any questions or concerns, which is an essential factor when investing in automotive products.

This durability means fewer worries about replacements or repairs, allowing me to focus on enjoying my driving experience.

Moreover, the EVIL ENERGY Oil Catch Can is compatible with both configurations of the PCV system. Users have the option to install it with a breather filter for pre-PCV cars as a vent system or without the breather filter for a sealed can setup between PCV hoses. This versatility caters to different vehicle setups, making it a smart investment for a wide audience. It’s great to have a product that adapts to my needs rather than forcing me to adapt to it.

It’s important to note that in freezing temperatures, the crank vent system can generate increased moisture, which may lead to freezing risks. To mitigate this, the manufacturer recommends cleaning the catch can weekly or reinstalling the original PCV hose in cold conditions. This proactive approach to maintenance ensures that I can enjoy the benefits of the oil catch can year-round, without worrying about potential blockages or performance issues during the winter months.
