MAD BMW S55 Oil Catch Can for M2 Competition, M3 & M4 | Cleaner Intake Airflow
Aug 17th 2026
The BMW S55 is built to handle serious performance, but like any high-performance turbocharged engine, its crankcase ventilation system can carry oil vapor back into the intake tract during normal operation.
The new MAD BMW S55 Oil Catch Can Kit provides a dedicated collection point for that oil vapor, helping reduce the amount of oil residue that makes its way into downstream intake components.
Designed specifically for the BMW M2 Competition, M3, and M4, the MAD Oil Catch Can combines a compact design with vehicle-specific mounting hardware for a clean installation that integrates naturally into the S55 engine bay.
Why Use an Oil Catch Can?
During engine operation, crankcase gases are routed through the ventilation system. These gases can contain suspended oil vapor, which can eventually travel toward the intake.
An oil catch can intercepts those vapors and collects the oil before it continues through the intake system.
By providing a dedicated collection point, the MAD Oil Catch Can helps:
- Reduce oil residue entering the intake tract
- Keep the intake air path cleaner
- Separate oil vapor from crankcase gases
- Provide an easy way to monitor and collect accumulated oil
For S55 owners who regularly drive their cars hard or run performance modifications, maintaining a cleaner intake system can be an important part of long-term engine maintenance.
Designed Specifically for the S55
The MAD Oil Catch Can isn't a universal can mounted wherever space is available. The kit was developed specifically around the S55-powered M2 Competition, M3, and M4.
A vehicle-specific mounting bracket securely positions the catch can within the engine bay, while the supplied formed hose provides a clean connection between the catch can and the crankcase ventilation system.
The compact black finish keeps the installation discreet and complements the factory engine bay.
A Clean, Complete Installation
The MAD Oil Catch Can Kit includes the components needed for a coordinated installation:
- Oil catch can
- Vehicle-specific mounting bracket
- Formed connection hose
- Hose clamps
- Mounting hardware
The result is a clean setup without unnecessary hoses or clutter throughout the engine bay.

Built for Modified and Stock S55s
An oil catch can can be a useful supporting modification regardless of whether your S55 is completely stock or part of a larger performance build.
For enthusiasts running increased boost, upgraded turbochargers, or other engine modifications, keeping the intake system as clean as possible becomes even more important.
The MAD system provides a straightforward way to add additional crankcase oil-vapor management without significantly changing the appearance or layout of the engine bay.
