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!

Not like before
This was the second time I’d used this product and this shipment was not like the first order I’d gotten. This one had the texture of pudding and there was no way you could walk outside and be seen in public after applying it. It looked like mud smeared all over your body. You had to put it on at night wake up in the morning and shower, and most of it came off. You also had to clean your sheets because it was on everything you touched. This batch was complete garbage and a total waste of my money!

Really lovely skincare
I was a bit skeptical with how this would do with my skin. I have had a hard time finding products that work and feel nice and don't leave my skin feeling raw. I absolutely love this stuff. It not only feels nice when using, my skin feels so smooth and so soft after. There is no "raw" feeling or overly tight feeling. My skin feels hydrated, it looks even, my pores are a little smaller and the overall appearance is bright and healthy. I will be buying the full sizes of everything once I am out of these! You should absolutely give it a try.

Years worth if wasting money on bad products that just don’t work. THIS IS THE ONE!!
I wish I had taken before photos to show what an amazing difference this stuff makes! I was just about to break down and buy a $79 bottle of Hyaluronic Acid (although I wish they did not call it acid lol). I decided to check Amazon reviews and it had fairly good reviews, but there was one that actually had better reviews and was a fraction of the cost! Obviously this was too good to be true but warranted a try. OMG, since trying this set, I have seen a HUGE different in fine lines, blemishes and over all look of my skin! I would have never believed it if I had not seen it for myself. I have my husband hooked on it now too as well as two daughters in laws! They say they find because it balances out blemishes and pores they need less makeup. This product is an amazing product and a ridiculously good price point! I wish I could buy a lifetime supply before they raise the price lol. I love this stuff and am throwing out a huge amount of expensive products since I now have one that actually works, and just happens to be very fairly priced. Note to the manufacturer; please don’t stop making these products!

Simple routine, calm skin, zero drama
This set does exactly what it’s supposed to do, which is surprisingly refreshing. The cleanser is gentle but effective—no tight, squeaky-clean regret afterward. The hyaluronic acid hydrates without feeling sticky or like it’s just sitting on top of your face doing nothing. Everything layers well, absorbs quickly, and doesn’t pill or pick fights with the rest of your skincare. After consistent use, skin feels calmer, more balanced, and less prone to random nonsense. No fragrance, no hype, no pretending to be magic. Just straightforward products that quietly improve your skin while minding their own business. If you want a routine that works without requiring a PhD or a 12-step ritual, this is it.
