Flowkooler high flow pump 1670 for the LS motor has a CNC machined billet impellers are designed with an increased vane count and a reduced plate-to-impeller clearance to achieve greater flow rates, higher head pressure and a more efficient flow than other OEM water pumps. The color is due to Type II Class II military grade anodize 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!

Slim but comfortable sizing looks upscale, wrinkle free from the dryer
Size: Medium, Color: Denim Blue
This is a very nice upscale looking shirt. It has great styling that is not over-sized. My husband normally wears a medium or large depending on the cut/style. He got a medium in this size and it is a perfect, comfortable fit. It arrived with some creases in the material from being folded in the packaging but it came out beautifully from the dryer. I'm happy he has a casual but nice shirt to wear when he takes me out to dinner!

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

A true vacation find!
Size: Medium, Color: Light Green
Really nice choice. Got it for my husband and he really liked the style. I loved how it fit on him and the lightness of the fabric. Great for hot, sunny weathered days, or warm nights. A true vacation find. Both comfy and stylish. He would have preferred it be 100% cotton, but I think he didn't really mind after steaming it. He commented on the color too. A beautiful sage green!

Well made, comfortable and flattering
Size: 3X-Large, Color: Light Green
Nice material. I ordered the 3XL because my hubby has a big belly. It fit him well and was slimming. He wore it as a guest to an outdoor wedding. He looked nice and was comfortable all night.

Nice but short
Size: X-Large, Color: Lavender
Yes, I purchased this shirt for my husband to wear on Mother’s Day. He looked so handsome and the color complimented his skin tone beautifully. The only con that my husband expressed was that the shirt was short but was comfortable and the fabric felt good on his skin. He is 6’3” and usually wears an XLT. Coofandy, Please make these shirts for taller, longer torso men!
