Flowkooler designed a high flow water pump with a CNC machined billet impeller for the CW rotation. It has an increased vane count and a reduced casting to impeller vane clearance to achieve 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

Small block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller for the CW rotation.  It has an increased vane count and a reduced casting-to-impeller vane clearance to achieve 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 Ford 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!

Lightweight, easy to apply, and perfect to use over makeup!
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
This has become my go-to sunscreen, especially for days when I’m in and out of the sun and need quick, reliable coverage. The spray goes on light and even, no thick, sticky feeling or weird white cast. I have sensitive skin and usually react to sunscreens with fragrance or heavy ingredients, but this one has not caused any irritation. I also appreciate that it's fragrance-free and water-resistant, so I can wear it at the beach or on a hike without worrying about reapplying constantly. It feels more like skincare than sunscreen, and I feel confident applying it over my makeup, not worrying that it will make it look cakey or run.

Good SPF spray. Poor spray bottle.
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
One of the three bottles we got stopped dispensing the spray immediately. The other two were difficult to keep working. The SPF performance was very good. Used in Cabo.
