Flowkooler high flow pump 1641 for the Ford L6 has a CNC machined billet impeller designed with an increased vane count and a tighter impeller clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Pontiac engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Good Wire. Will definitely consider for the future.
Size: 2 Colors each 5FT, Style: 10AWG
Nice wire. Comes inside a plastic bag. Wire is soft and flexible. Worked as exactly needed for my boat wiring. It was easy to cut and crimp connectors on. It has a thick layer of insulation around the wire which keeps it from getting damaged.
