SMG Pressure Accumulator Upgrade, MLR - E46 M3

This SMG accumulator upgrade has a heavy-duty piston and internals to keep pressure stabilized. Pressure for the fluid in the SMG pump is the most critical action for proper SMG operation. The system requires a minimum PSI to operate and the accumulator with its internal piston is supposed to keep a supply of fluid ready for the pump. This upgraded accumulator does a better job of maintaining pressure and puts less stress on the pump. It's also rechargeable without removing the tank or the pump.

Available in two sizes -
Standard size that is the same as stock and fits with all of the original hardware and bracket
Oversized. This requires a larger mounting bracket and hardware. This is a special order that may take additional time for processing and shipment. We will also contact you for additional installation and use details.
