I have analyzed current buyer feedback and the technical specifications of several popular aftermarket components to bring you this comparison. I truly believe that the correct accessories are just as vital as your oil choice. Here is an honest, ranked look at these parts.

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 unit earns my top spot because it excels at the core task of blow-by prevention, which is a known necessity for the 6.4L HEMI platform. By capturing oil vapors before they recirculate into the intake, it keeps the valves cleaner over time.
I favor this design because the 6 oz capacity is generous enough that you will not have to empty it constantly. It strikes the right balance between functional engineering and ease of installation for the average owner.
Owners frequently praise the sturdy construction of this canister.
The installation process is widely considered straightforward for DIY enthusiasts.
Buyers note that the unit effectively traps oil that would otherwise coat the intake.

A common complaint regarding this model is its smaller 3 oz capacity, which requires more frequent attention than larger versions. However, this is a necessary trade-off for the tight clearances found in the Hellcat engine bay.
I would point high-performance owners toward this piece because it is specifically shaped to fit the unique layout of supercharged setups. It is a solid, compact solution for managing oil mist in demanding engines.

Compared to the Evil Energy kit I ranked first, this unit prioritizes visual impact with its vibrant color finish and polished construction. It is clearly designed for the owner who wants their engine bay to look as aggressive as the car performs.
I think this is a great addition for anyone attending local car shows. While the Z-bracket provides a clean mounting point, the primary draw remains its ability to dress up the engine compartment.

This pump became popular due to reports of its high flow rates, but I suggest approaching this as a specialized repair part rather than a casual upgrade. It serves a specific need for those managing internal oil pressure issues.

It is recognized as a compatible replacement for 5.7L and 6.4L engines.
Professional installers often cite its importance during a full engine overhaul.

This separator takes the top spot for high-performance filtration because of its advanced internal multi-stage filter system. It is designed to be more efficient than standard cans, making it my choice for forced induction engines that generate significant blow-by.
I value the engineering put into this specific model to ensure maximum separation efficiency. It is a premium accessory, but the long-term protection it provides for your intake system is worth the investment.
Users frequently highlight the effectiveness of the multi-stage filtration system.
The black finish is praised for a stealthy look under the hood.

Choosing Between Them
In my view, the EVIL ENERGY Oil Catch Can stands as the best recommendation for general maintenance, while the J&L 3.0 Oil Separator is the superior choice for high-performance setups. If you just need a functional replacement part, the E-Vniko Dipstick offers great value for the average owner. For those focused on engine bay style, the Billet Z-Bracket Catch Can is a perfect fit, and I suggest only considering the Aulink Oil Pump if your engine requires internal repairs.
Keep in mind that while these accessories provide essential blow-by protection, they are not set-it-and-forget-it components. Most of these units require periodic manual draining to remain effective, so make it a habit to check your levels during every oil change to keep your HEMI running smoothly.
