Water Pump

Subaru downgraded the performance of their water pumps starting with MY2004 by going from the closed back cast pump impeller to the more economical stamped open back impeller. The stamped impeller pump is less efficient and more susceptable to cavitation. We suggest installing a closed-impeller pump on any performance or motorsport Subaru engine build. Pump kit includes pump, pump gasket, and thermostat gasket (all OEM).
