Mr. Gasket water pumps are a great way to free up horsepower and add consistent cooling to high performance engines. They eliminate common issues found in traditional mechanical water pumps - parasitic horsepower loss, heavy cast iron housings and impeller drag. This cast aluminum pump flows 35 gallons per minute and comes in a black coated finish.
