Bimmerworld Power Steering Reservoir (E9X M3)
The BimmerWorld E9X M3 Power Steering Reservoir is a direct replacement for your undersized OEM reservoir. The stock reservoir is simply too short to be truly useful, and with high-RPM track use, it tends to allow the fluid to overflow. This often leads to costly and damaging fluid starvation of the pump and an irritating mess in the engine bay, let alone the potential mess outside the engine bay.
This all-aluminum, fully-baffled tank is significantly larger than stock and includes adapters to accept the OE hoses.
