This Genuine BMW E46 M3 CSL SMG Fluid Expansion Tank and Mounting Bracket is a required component when installing a CSL Carbon Airbox or an SMG Pump Relocation Kit on the E46 M3. The original SMG fluid reservoir must be relocated to accommodate these installations, and this OEM expansion tank with its dedicated mounting bracket ensures the SMG hydraulic system remains properly housed, mounted, and functional after the modification.

This is the factory OEM component used on CSL-specification E46 M3 vehicles, providing the correct fitment, fluid capacity, and hardware needed for a clean, reliable installation. It is an IND-bundled item combining the reservoir and bracket as a complete set.
