HPR Tuning has partnered with the American company Improved Racing to create the first bolt-on transmission fluid adapter with a thermostat for the 8HP transmissions found in 2012+ Ram 1500 trucks. This thermostat includes adapter sleeves for transmissions with 17mm and 18.5mm unthreaded ports.

The adapter's built-in thermostat automatically bypasses the transmission cooler until the fluid reaches 160ºF. The thermostat reduces rough shifts caused by overcooled transmission fluid, reduces wear, and improves efficiency and horsepower. The transmission can now reach operating temps quickly with large aftermarket transmission coolers. This allows for high cooling capacity without sacrificing drivability.

The adapter features -8AN male connections for aftermarket AN lines.

Important Application Notes:

  • The adapter can only be used in conjunction with external transmission fluid coolers.
  • The adapter does not directly connect to the factory lines. Aftermarket AN lines must be used.
  • The adapter will only help resolve rough shifting issues if they are caused by overcooling of the transmission, usually due to the addition of a larger aftermarket transmission cooler.

Features and Benefits

  • Bolt-on fitment for 2012+ Ram 1500 truck 8HP series automatic transmissions with 17mm and 18.5mm unthreaded ports.
  • Built-in thermostat prevents temperatures from dropping below optimal levels, reducing wear, improving efficiency and horsepower, and helping to eliminate rough shifting.
  • -8AN male connections.
  • 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish.
  • Thermostat portion is made in the USA by Improved Racing. Adapter portion is made by us at HPR Tuning.

Great for hair and skin. Great buy.
These pillow cases are great for my hair and skin. They look good, hold up well in the washer and dryer, and the price is great. They are cooling. Of course I wish they could be more cooling, but honestly I'm not sure that's even possible. Great pillow cases. Already bought more for other heads. Would buy again.

Hot hot hot. Side sleepers will hate it
At first touch, these are the coldest pillowcases I own … but only for seconds. Once you actually lay on them, within seconds they adjust to your body temp, the heat feels trapped, my head begins to feel hotter than before I laid down - which has in turn caused me loathe these pillow cases. I hate that I have missed the return window. Would never buy again, would never recommend. My satin ones aren’t even this hot! I gave them the good ole 30-day try. Side sleepers - if you are like me and sleep on your side with arm tucked under pillow - flipping this pillow over in hopes of a cold side - forget it, it’s already hot from your arm.

Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.
