What to Look For Before Buying

When picking an oil catch can for a 5.7 HEMI, I weigh fitment, build quality, and maintenance needs. The right can should mount solidly, filter oil vapor well, and drain without leaks. I favor billet aluminum for durability and a sturdy bracket for flexible installs. Also check what hardware is included, the warranty, and how easy it is to service over time.

Check Consideration 1 – Fitment And Compatibility

Consideration 1 – Fitment And Compatibility: Make sure the can is designed for the 5.7L and 6.4L HEMI family and fits your exact Dodge, Challenger, Charger, or Jeep Grand Cherokee. Check where it mounts and how much space is left in your engine bay to ensure the Z-bracket or alternative mount will fit without rubbing belts or hoses. If it’s compatible with Mopar PCV plumbing, that helps minimize relocation and leaks.

Value Consideration 2 – Construction Quality And Materials

Prioritize billet aluminum with a durable finish (anodized or painted) for heat and corrosion resistance. A knurled drain, O-ring seals, and high-quality hose ends reduce leaks and maintenance. A tight tolerance design helps prevent oil creep into the intake system over time.

Rating Consideration 3 – Filter Performance And Maintenance

Look for a true filtration stage (mesh or diffuser) to trap oil vapors before reaching the intake. Confirm the capacity supports your driving style, and note any recommended drain intervals. Easy access for draining and cleaning extends service intervals and keeps performance consistent.

Verify Consideration 4 – Included Hardware And Warranty

Choose a kit that includes hoses, fittings, and clamps for a complete bolt-on install. A warranty or lifetime support adds peace of mind for long-term ownership. Verify the required tools and steps to complete the install without modification.

Frequently Asked Questions

What is the main benefit of an oil catch can on a HEMI engine?

It traps oil vapor and moisture from blow-by gases before they reach the intake, reducing carbon buildup on valves and the manifold and helping sustain combustion efficiency and power.

Do I need a large-capacity catch can for daily driving?

For daily driving, a modest capacity with a good filtration system is usually sufficient. Frequent draining is less of a concern when the can is easy to access, but larger capacities reduce maintenance frequency during long drives.

Will a Z-bracket fit my vehicle correctly?

Z-brackets are designed to simplify mounting in common HEMI engine bays. Verify the bracket’s mounting points align with your model year and engine layout to ensure a proper fit without interfering with belts or hoses.

Is billet aluminum worth the extra cost?

Billet aluminum offers superior strength, heat resistance, and corrosion protection. It tends to last longer and maintain a premium engine bay appearance, making it worthwhile for enthusiasts seeking durability.

How often should the catch can be drained?

Drain intervals depend on driving conditions and oil vapor generation. Start with a monthly check, then extend or shorten intervals based on observed accumulation and driving style.

🎯 Final Verdict

My top pick is the RANSOTO unit for its premium billet construction, exclusive Z-Bracket, and a complete bolt-on kit. It offers durable performance, easy maintenance, and a refined engine-bay look that fits both daily drivers and enthusiasts seeking a high-end upgrade. As a strong alternative, the 6.4L Billet Kit with the new Z-Bracket provides similar durability and a full install. I’d recommend the RANSOTO for the best balance of build quality and install convenience, with the 6.4L kit as a close second for broader compatibility.
