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!

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.

the lies
Format: Kindle
This is amazing fast pace read that is full of plot twists and lies that keep getting bad. This is a story we’re a omega has been lied to by her mother and finds out that someone is slowing dieing. 3 alpha take the omega and feed her more lies so they can use her against her father so they can find their mate Kelly. This is a dark read and ends in a cliffhanger and so good.

Ends in a cliffhanger
Format: Kindle
Thankfully, the next book is already available. Roxy Collins is the queen of omegaverse slow burn. This particular series is omegaverse with wolf shifters. Thoroughly enjoyed this book! Lots of suspense and trying to figure out what is true and what's really going on. I loved it! Pretty spicy once the action starts. Heats are pretty much always spicy. There is a little bit of male interaction, but not full-on shmex. Definitely recommend.

Epic!!!!
Format: Kindle
Absolutely addicted from the first page. The twists and turns, world building and character development all come together for the perfect Omegaverse. And let's not forget that spice because knots are life and these are spectacular. Running for book #2 because that cliffhanger was torturous.
