Upgrade from the plastic impeller on the stock water pump to this aluminum impeller pump originally developed by BMW for the M3 GT4. This aluminum water pump was designed to stand up to the abuse of racing but can be used on a standard street car. Plastic impellers are earlier BMW's had a tendency to degrade over time and eventually break apart. While we have not seen this issue on the S65 engine as yet, why not get some piece of mind with this original BMW aluminum impeller water pump.

This item fits the following BMWs:
2006+ E90 BMW M3 - Sedan
2007+ E92 BMW M3 - Coupe
2007+ E93 BMW M3 - Convertible
