BOMLING 6.4L Billet Oil Catch Can Kit for 2011–2021 6.4 HEMI — Black, Z-Bracket Mount & Patented Diffuser

BOMLING's 6.4L billet oil catch can kit is a complete air-oil separator system engineered to trap crankcase oil vapor before it reaches the intake on 6.4 HEMI engines (2011–2021 Charger, Challenger, Chrysler 300).

This kit combines a large-capacity billet catch can, updated Z-bracket mounting, forged fittings and a patented diffuser to reduce oil and vapor transfer through the PCV/UPR path. It’s made to be a direct, durable solution for drivers who want to limit oil contamination in the intake tract, maintain cleaner intake components and provide an accessible, serviceable reservoir for captured oil.

How does this catch can attach and fit my 6.4 HEMI?

The BOMLING kit includes a new Z-bracket specifically designed for 2011–2021 6.4 HEMI engine bays and necessary billet hose ends and forged fittings for a secure installation. The bracket improves mounting geometry and helps position the can away from hot or moving components, allowing for clean routing of PCV hoses.

• Includes Z-bracket and hardware tailored for Charger, Challenger, Chrysler 300 6.4L models.
• Billet hose ends and forged fittings for OEM-style connections.
• Compact footprint for fitting in tight engine compartments.

What filtration and separation does the system use to trap oil?

The can uses a multi-chamber internal design with a patented diffuser that cools and condenses oil vapor so it coalesces and drains to the reservoir. The layered filtration prevents oil droplets from re-entering the intake while allowing only vented air to return or vent safely to atmosphere.

• Patented diffuser and chamber filtration to separate vapor from air.
• Condensation surfaces and baffle channels reduce re-entrainment of oil.
• Clean-air outlet only, minimizing oil carryover to intake.

How do I service the catch can and what capacity does it hold?

The billet tank offers a large 4 oz (approx. 6.4L marking is model series) capture volume and a serviceable drain point so owners can empty collected oil quickly during routine maintenance. The CNC billet construction includes easy-open fittings and a visible drain area so you can check and remove accumulated oil without removing the entire assembly.

• 4 oz capture reservoir with accessible drain/discharge point.
• Billet construction for straightforward opening and resealing during service.
• Maintenance intervals depend on driving style; inspect during regular oil changes.

Will this kit prevent intake contamination and what are the limits?

This catch can significantly reduces oil vapor and particulate entering the intake, which helps keep throttle bodies and intake valves cleaner over time. It is not a cure-all — heavy blow-by or poorly functioning PCV components can still introduce oil; regular inspection and proper installation are required for best results.

• Reduces oil carryover to intake systems when installed correctly.
• Compliments existing PCV components but does not replace engine diagnostics or repairs.
• Best used as part of proactive maintenance to limit carbon and oil deposits.

Who is this for? BOMLING’s billet oil catch can kit is aimed at owners of 6.4L HEMI-powered Dodge Charger, Dodge Challenger and Chrysler 300 models (2011–2021) who want a robust, serviceable way to minimize oil contamination in their intake systems. It’s suited to daily drivers, performance enthusiasts, and anyone performing regular engine maintenance who values a durable, CNC-machined assembly with upgraded fittings and bracketry for a clean, reliable installation.
