Burger Tuning BMS Oil Catch Can Kit for 2021+ Mazda 3 & 2019+ CX-30 SKYACTIV® 2.5L Turbo

Protect your Mazda's turbocharged engine with the Burger Motorsports (BMS) Oil Catch Can Kit, specifically engineered for the 2021 and newer Mazda 3 and 2019 and newer Mazda CX-30 equipped with the SKYACTIV® 2.5L turbocharged engine. Designed to help control oil blow-by and crankcase vapors, this high-flow oil catch can system helps reduce oil contamination in the intake tract, intercooler, charge piping, intake valves, and intake manifold.

Turbocharged Mazda SKYACTIV® engines can experience oil vapor accumulation in the intake system due to crankcase ventilation and oil blow-by. As boost pressure increases, these issues may become more noticeable. Oil deposits can contribute to intake system contamination and may affect engine performance over time. The BMS Oil Catch Can Kit is designed to help address this issue by separating oil from crankcase vapors before they return to the intake system.

Engine Protection and Oil Separation Technology

Unlike universal catch cans that may use restrictive internal passages, undersized hoses, excessively long hose routing, or inadequate baffling, the BMS Oil Catch Can Kit is engineered specifically for the turbocharged Mazda 3 and CX-30 applications listed below. Its design prioritizes efficient oil separation while maintaining the airflow required for proper crankcase ventilation.

The system features a precision-machined aluminum catch can with a non-clogging triple-baffle air/oil separation system. This design helps capture oil droplets and contaminants while maintaining high airflow and minimizing unnecessary restriction. The large inlet and outlet passages measure over 16 mm, exceeding the original equipment manufacturer (OEM) PCV piping size as specified by BMS.

Custom heavy-duty silicone hoses are designed to maintain a high flow rate throughout the system. The unrestricted design helps minimize excessive crankcase pressure that can occur with more restrictive catch can configurations. The kit also retains the factory fully closed-loop positive crankcase ventilation (PCV) system, helping prevent crankcase vapors from being intentionally vented directly into the atmosphere.

Precision Construction and Vehicle-Specific Mounting

The BMS Oil Catch Can is precision CNC-machined from solid blocks of high-grade aluminum, with 100% CNC-machined construction and no welded joints. The lightweight aluminum can features a durable anodized black finish for a discreet, factory-style appearance in the engine bay.

The included billet aluminum mounting bracket is CNC-machined and designed around the Mazda 3 and CX-30 turbo engine bay. Its mounting locations help minimize hose length and support efficient system operation while maintaining a clean, stealth appearance.

Installation takes approximately 20 minutes, according to the manufacturer, and the kit includes the required mounting bracket, hoses, and installation hardware. The system is fully reversible, allowing the vehicle to be returned to its original configuration.

Easy Maintenance and Oil Disposal

Captured oil can be removed by unscrewing the catch can's base or using the drain plug, as applicable to the installed configuration. The collected oil should be disposed of responsibly with used engine oil during routine oil changes.

The manufacturer describes the triple-baffle air/oil separation system as non-clogging and requiring no dedicated servicing of the separation mechanism. However, the catch can itself still needs to be checked and emptied periodically. BMS recommends emptying the can approximately every 3–6 months, with the appropriate interval depending on driving conditions, engine use, and the amount of oil collected.

The catch can is guaranteed for the life of the vehicle according to the manufacturer.
