Why fit an oil catch can on the E46 M3 S54
The high-revving S54 is known for blow-by and moisture returning to the intake. A quality, baffled oil catch can reduces oil vapour and water mist entering the intake system, helping to minimise intake valve deposits, reduce carbon build up, improve crankcase ventilation performance, and prevent the notorious winter freezing issues. Expect a cleaner intake tract, cleaner valves, and happier long-term engine health on both fast road and track-driven cars.
