Burger Motorsports B58 Crankcase Vapour Separator Kit for BMW F-Series M140i, M240i, 340i, 440i

Important: Requires the BMS B58 Intake to install on M140i, M240i, 340i and 440i.

Keep oil mist and blow-by out of your induction system and safeguard performance on your turbocharged B58 engine. This Burger Motorsports catch tank is a dedicated B58 breather solution that traps oily vapour before it contaminates your intercooler, charge pipework and intake valves. Precision CNC machined from billet aluminium and anodised black, it is a direct, vehicle-specific upgrade for BMW F-series M140i, M240i, 340i and 440i owners who want cleaner airflow, stronger consistency and long-term reliability on stock, remapped or track-driven cars.

We run this BMS kit on our own B58 builds and our customers have been genuinely impressed with the amount of residue it captures. Expect a tidier intake tract, reduced valve coking on the direct injection B58, and repeatable power on spirited road or track days. If you are searching in the UK for a BMW B58 blow-by separator, crankcase catch tank or PCV upgrade for your F-series six-cylinder, this is the package to choose.
