BimmerWorld Moroso Aluminum Power Steering Reservoir - BMW E9X M3

The BimmerWorld Moroso E9X M3 Power Steering Reservoir is a direct replacement for the undersized factory reservoir, designed to address a common issue during high-RPM and track use. The factory reservoir has limited capacity and can allow power steering fluid to overflow under demanding conditions, potentially leading to fluid starvation at the pump, reduced performance and an unwanted mess throughout the engine bay. BimmerWorld’s upgraded reservoir is manufactured entirely from aluminium and features a fully baffled internal design to help maintain a consistent fluid supply during hard cornering and sustained track driving. Its significantly increased capacity provides greater fluid volume than the OEM reservoir, while supplied adapters allow it to connect directly to the factory power steering hoses for a straightforward installation.
