PRWs high flow aluminum water pumps are engineered to deliver an increased water flow. These super velocity pumps significantly improve cooling for all street, high performance and racing applications. With special cast-iron impeller and tight clearances, PRW High Performance Aluminum Water Pumps provide increased coolant flow, block pressure, and balanced delivery. Each pump features low pressure-injected, aluminum alloy pump bodies that are complemented by a precision cast-iron impeller design. This helps minimize engine hot spots at any speed.
