BMW Z3 High Performance Water Pump

The water pump supplied from the factory for the BMW Z3 was designed to meet the demands of average daily driving.

Designed for performance and durability, the High Performance water pump from EMP Stewart increases flow a full 20 percent over stock, while using a highly efficient stainless steel impeller to reduce parasitic draw.

Add a heavy-duty bearing and high quality water seal, and you have a pump durable enough for daily driving and tough enough for the track.
