This was a perfect replacement part. Since I was replacing my thermostat assembly (Wahler - Direct Replacement) anyway this was a very easy installation. Perfect bolt-on fit with no additional gasket material or sealant needed, and the metal impeller looked like it would move more coolant with less effort. Highly recommended vs. BMW's OEM part and price. Thanks FCP!!

Replaced my plastic impeller water pump that rattled and chirped like crazy. The fan was all over the place. Pretty impressed with Graf. Looks very nice. The metal impeller is a must. Doesn't look cheaply made either. After installed the motor purrs like a kitten. No rattle or chirp anymore. A+++

Second only to the stewart, but given that it is less than half the price it makes quite the bargain.
