BMS BMW N54 535i Oil Catch Can Kit – E60/E61 2007-2010 | Burger Motorsports Closed-Loop PCV, Double-Baffled | Fits 535i/535ix

Burger Motorsports N54 Oil Air Separator for E60 and E61 535i 2007 to 2010

Keep your twin turbo 3.0 litre 5 Series breathing clean with this dedicated crankcase breather upgrade. This catch tank is engineered for the N54’s PCV system to limit blow-by vapour reaching the intake tract, helping reduce intercooler oiling, charge pipe contamination and direct injection valve deposits. The result is consistent performance, smoother running and long-term protection for your 535i or 535i xDrive.

We run this unit on customer cars and in our own builds. The fit is neat under the scuttle panel, the machining quality is spot on and our buyers regularly report cleaner pipes and less oily residue in the system. It looks OEM-plus and works exactly as enthusiasts expect.

Key reasons to choose this N54 catch tank

• Designed specifically around the N54 crankcase ventilation layout for correct flow and separation
• Hidden cool-side mounting beneath the cowl for effective condensation and a stealth finish
• Sealed recirculating configuration retains factory emissions function and avoids vent-to-atmosphere smells
• Large-bore 16 mm plus ports and hoses for minimal restriction and stable crankcase pressure
• Twin internal baffle stack for reliable air oil separation without clogging
• CNC billet aluminium body with a hard black anodised finish for durability
• Complete kit with brackets and lines, precision fit and fully reversible
• Easy servicing via removable base or integrated 1/8 NPT drain port every 3 to 6 months
• Made in the USA with a lifetime can warranty from Burger Motorsports

Built for the N54, not a universal compromise

Generic cans often mount on the hot side, use narrow lines or long hose runs that can upset PCV flow. This unit uses short routing, generous diameter throughout and free-flow internals. You get strong separation performance without adding restriction to the N54 breather system.

What you will notice

• Cleaner inlet paths on direct injection engines, helping to slow valve coking
• Less oil collecting in the intercooler and boost pipes
• More stable fuel quality and knock resistance by limiting oil mist in the intake charge
• Happier variable valve timing behaviour and healthier long-term operation
• Reliable performance on stock, Stage 1 or Stage 2 calibrations

Installation and servicing

Typical install time is around 20 minutes with basic tools. Everything required is included and the setup is fully reversible. To empty, unscrew the lower section or use the 1/8 NPT drain fitting.
