Aluminum SMG Expansion Tank 21532282549

This is a NEW custom aluminum expansion tank designed for a remote location away from the intake manifold.

Moving the expansion tank away from the intake manifold solves space constraints, reduces overall hydraulic fluid temperature and/or reduces common degradation of plastics due to high temperature environments such as the engine bay. 

Typical use cases of this product could also be:

• When installing a CSL type airbox on an M3 with SMG transmission
• Relocating the SMG pump
