The primary factor separating quality from junk in this category is consistent filtration, as poor designs fail to prevent sludge buildup in your Hemi’s intake. After analyzing performance data and buyer feedback, I have ranked these options by their long-term effectiveness. While my personal view favors robust protection for high-output engines, I have organized these choices to help you find the right fit for your specific maintenance goals.
1. EVIL ENERGY Oil Catch Can Compatible with Dodge Charger Challenger 6.4L 2011-2022 Chrysler 300 5.7 HEMI SRT8 Air Oil Separator Kit 6 oz
This kit earns its place as the budget catch can because it provides an accessible entry point for owners wanting to protect their intake tract without overspending. It uses a multi-stage honeycomb filter that effectively traps oil vapors before they reach your valves.
In my view, this is the most straightforward option for a daily driver. Just remember that it is not CARB-exempt, so you should verify your local emissions rules before installing it.
Buyers frequently praise the simple, tool-free drainage of the tank base.
Users report that the included Z-bracket simplifies the installation process significantly.
The most common advice is to monitor the 6oz capacity strictly during the first few weeks.

This pump is ideal for the performance enthusiast who has modified their engine and requires higher oil pressure to prevent internal damage. It is engineered to meet strict quality standards, ensuring that vital engine parts stay lubricated under stress.
I find that this component is a necessary upgrade if you are pushing your Hemi beyond stock power levels. It is a specialized part, so ensure your specific model year and engine displacement match the manufacturer's fitment list.

The most surprising aspect of this tool is its stainless steel construction, which prevents the rusting issues often found with cheaper plastic or flimsy metal alternatives. It serves as a reliable measuring gauge to ensure your oil stays within the safe range marks.

The most common complaint regarding this unit is the smaller 3oz capacity, which requires more frequent emptying than larger kits, yet it provides a balanced solution for tight engine bays. It uses high-quality NBR hoses and quick-connect fittings that fit the complex layout of the Hellcat platform perfectly.
I think this is a smart choice if you have limited space, as the compact design tucks away neatly. It is built specifically for the unique demands of forced induction engines, keeping your intake tract cleaner.

5. J&L Oil Separator Co. 3.0 Oil Separator Compatible with 2011-2023 Charger Challenger Cherokee 300C & 2018-2024 Durango 6.4L Hemi Passenger Side (Black)
Unlike the Hellcat-specific unit, this system offers a more refined, premium design that utilizes a larger reservoir and more advanced separation technology. It stands out to me because it is specifically calibrated for the 6.4L Hemi, offering superior protection against oil blow-by.
I consider this the best all-around choice for someone who prioritizes engine longevity above all else. It is a robust, well-constructed component that integrates cleanly into your engine bay.
Many owners highlight the high-quality finish and solid construction of the unit.
Users consistently report that the installation process is intuitive and fast.

Choosing Between Them
If you want the best for your engine, I recommend the J&L 3.0 Oil Separator for its superior filtration capabilities. For budget-conscious owners, the Evil Energy 6.4L kit serves as a reliable alternative, while the Aulink high-pressure pump and replacement dipstick round out the needs for performance builds and routine maintenance. I believe these choices cover the essential requirements for any 392 owner looking to protect their investment.
Regardless of which catch can you select, you must commit to regular maintenance to keep your engine running at its peak. Failing to drain the reservoir can lead to overflow, which defeats the purpose of installing these performance upgrades in the first place. Treat your engine with care, and it will respond with the reliability you expect from a Hemi.
