Burger Motorsports BMS Oil Catch Can – BMW M140i / M240i / 340i / 440i (F20 / F21 / F22 / F23 / F30 / F32 / F33 / F36, Gen 1 B58)

OVERVIEW

This BMS catch can is built for the first-generation B58 turbo six in F-chassis BMWs. It intercepts oil vapor, fuel and water that the crankcase ventilation system would otherwise feed into the intake, where it builds up as carbon on the valves and coats the turbo inlet.

Machined from billet aluminum without welds and black anodized, the can uses three internal baffles and large 16 mm+ connections while keeping the factory closed-loop PCV routing intact. It is designed to mount alongside the BMS B58 intake, takes roughly 20 minutes to fit, and can be removed without leaving a trace.
