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.

Runs much bigger than expected
Size: 8.5, Color: White
Nice design and looks good, but sizing is completely off. Ordered 8.5 (usual size) and it fits much larger, closer to a 9.5. Already did two exchanges and both had the same issue. Not reliable sizing.

Makes a lot of noise when walking
Size: 10, Color: Black
I wore this for the first time, and it kept making swushing noises. It was extremely embarrassing to walk around on them. However they are comfortable.
