Flowkooler high flow pump 1621 has a 16 vane CNC machined billet impeller. It is shrouded and ported and, with the increased vane count and a reduced impeller clearance, it really pumps the coolant. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller's 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 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.
From 0-3,300 RPM…Nothing Beats a FlowKooler!

Cute Tray, Bad Charger

Little pricey, but worth it
Very nice product. Creates a clean look on my fiances night stand rather than having everything all over the place. I like the little compartment with the door, its nice for putting things out of sight. The coin compartment is nice as well. The curve of the bottom makes it easy to get the coins out. I do think its a little pricey for what it is, but i still feel it was worth it to organize the clutter.
