When I first came across the WENJTP Oil Catch Can Kit, I was immediately intrigued by its comprehensive design and practical features. This kit stands out primarily because of its universal compatibility and thoughtful construction, making it a solid choice for anyone looking to enhance their engine’s performance and longevity. The 5 oz (approximately 150ml) capacity may seem modest, but I appreciate how this size balances effectiveness with ease of maintenance — it’s large enough to capture a meaningful amount of oil vapor yet small enough to clean regularly without hassle.

One of the biggest advantages for me is the universal fit, which covers a wide range of popular car brands such as Honda, Toyota, Nissan, Lexus, Mazda, Jeep, Dodge, Ford, Chevy, and Volvo.

The inclusion of 4 adapters and a breather filter drain valve plug adds versatility, allowing for a tailored installation that fits your specific engine setup. This flexibility really impressed me because it eliminates many compatibility worries upfront.

The enhanced filtering system is another feature that caught my attention. The washable breather filter works hand-in-hand with the internal baffle system in the oil reservoir tank to trap oil and reduce impurities from entering the intake manifold.

By keeping the engine cleaner, this catch can not only supports better performance but also contributes to prolonging the engine’s life — a benefit that any car enthusiast or daily driver would value highly.

What I found particularly user-friendly is the reusable design featuring a drain valve. Instead of having to uninstall or dismantle the can to empty it, you simply unscrew the valve and drain the accumulated oil. This convenience means I can maintain the system frequently without any fuss, ensuring optimal function at all times. The fact that the product now uses a tapered thread and includes thread seal tape to improve sealing shows the manufacturer’s commitment to quality and continuous improvement, even if it means the adapters don’t fully enter the oil catch can as depicted in earlier images.

Finally, the package itself is well thought out. It comes with a billet aluminum oil catch can, which is both durable and lightweight, a filter, a fully adjustable mounting bracket, five adapters, and two screws. This all-in-one kit provides everything needed for a secure and effective installation, allowing me to get started right away without the need for additional purchases.

Get It From Amazon Now: Check Price on Amazon & FREE Returns How a PCV Valve Catch Can Help Me I’ve found that installing a PCV valve catch can has made a noticeable difference in the way my engine runs and its long-term health. The PCV (Positive Crankcase Ventilation) system helps reduce harmful gases inside the engine, but sometimes these gases carry oil vapors that can build up inside the intake system. By using a catch can, I’m able to trap these oil vapors before they reach the intake manifold, which keeps my engine cleaner and prevents carbon buildup. This simple addition also helps maintain better engine performance and efficiency. Since the catch can stops oil and sludge from contaminating the intake, my engine breathes cleaner air, which improves combustion. Over time, this means fewer maintenance headaches for me and potentially longer engine life. For anyone wanting to protect their engine from unnecessary wear and keep it running smoothly, a PCV valve catch can is definitely worth considering.
