Introducing the Mishimoto 2021+ BMW G8X M2/M3/M4 performance heat exchanger, the ultimate solution to keep your charge air cool under the most demanding conditions. In the world of forced induction vehicles, air-to-water intercooling is the future, and Mishimoto are taking it to the next level.----We started from scratch, leaving no room for compromise. Our design eliminates all plastic components, replacing them with durable aluminum end tanks, core, and CNC-machined ports.

We've increased the core volume by 23 percent and expanded the external fin surface area by 44 percent. Combined with our dual-pass flow configuration and louvered fin design, this performance heat exchanger vastly improves cooling capacity over stock, enhancing overall performance.----Rest assured, the Mishimoto Performance Heat Exchanger for the 2021+ BMW G8X M2/M3/M4 is designed to fit perfectly with all other factory components, ensuring seamless integration into your vehicle. For added protection, we include steel rock guards to shield the heat exchanger from debris and prevent punctured tubes or crushed fins.

Not all the same! Some Great, some not.
I bought the queen 2 pillow green blue pillows first. Absolutely love them. Later I saw they had them with cooling on both sides and bought the queen 2 pillow set of that..not the one that said firm. These new ones are way over stuffed and very firm, they do not sink in softly like the first ones. So I would only get the green/blue tag ones they are 5 star-best i have used, this last one 3 star and regretting them. I took enough stuffing out of the two new ones to make 1.5 new pillows, now descent but not the soft comfort as the first, I thought that was what I was paying for. So it's a gamble. The lighter color stuffing is soft and has more of a memory foam reaction, the other darker one feels like stiffer foam with more air in it. It's still soft but doesn't feel like memory foam.

Starts off very cool
I got this pillowcase for my husband because he is always hot at night and has trouble falling asleep because of it. The fabric of this pillowcase feels very similar to a cooling pillowcase that I have had for years and love (but is discontinued, so I can't get any more of them). It is a silky smooth, not-quite-satin fabric that feels initially very cool to the touch. It fits on a standard size pillowcase, and has a slight pocket end (not very much overlap, so it does come untucked during the night).
My husband reports that this pillowcase is very cooling right when he goes to bed, but after a short while, it warms up and isn't really cool anymore. So if he doesn't fall asleep right away (and he usually doesn't), he has to flip it over. His head puts out a lot of heat at night though, so the pillowcase might stay cooler longer for others.

Doesn’t stay on the pillow.
Color: Gray, Size: Queen (2 Count)
The concept is there, but the pillow case doesn’t stay on. Every night the pillow case slides either half way or completely off the pillow.
If it stayed on I would love it
