A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.4L cooling system with the Mishimoto Ford 6.4L Powerstroke Low-Temperature Thermostats! These thermostats are designed as a direct-fit replacement for your aged factory units. The Mishimoto thermostats have a lower activation temperature (187 F/197 F) compared to the factory thermostats (192 F/203 F). The lower activation temperatures allow coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. These thermostats are ideal for use in warmer climates or under extreme towing/driving conditions. Pair this thermostat set with the Mishimoto 6.4L Powerstroke Aluminum Performance Radiator for a complete cooling system overhaul. As with all our products, these thermostats include the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.Shipping Notes

Finally, socks that fit and are comfortable
Size: X-Large, Color: White
I wear size 12.5 Wide shoes and have been through numerous "large" socks that shrink after the first wash and then are just too small. Local stores sell very few options in XL. Decided to give these a try and I'm glad I did. I like the height (just over the ankle joint) versus low cut or no-show, which tend to allow junk into the gaps.
I like the material. It's thinner on top nd doesn't have compression areas. It's not overly thick, so if you are looking for cushion or extra support, look elsewhere. I have the same sock in a no-show in gray, but they are size L and are just a little too small, so I knew ahead what I was in for construction-wise. Those have been plenty durable, so it checks all the boxes.
I'll be ordering some XLs in black and will keep on the lookout for gray.

Great socks / a bit expensive
Size: Large, Color: Black
These may be the Goldilocks of the socks I've tried. They have nearly the same quality as the MUCH pricier Darn Tough Vertex Ultralight Cushion Cool Max socks (also reviewed). They have better quality, and a higher price, than a similar pair of PUMA socks (also reviewed).
Pros: Very well made, with no loose stitching, comfortable forefoot and heel cushioning, good ventilation via top mesh, good arch compression, minimal logos and mostly solid color.
Cons: Price is a bit on the high side, but better than the Darn Tough socks.
I could honestly have made a good case for any of these three (ASICS, PUMA, or Darn Tough), which explains their collective high ratings. I did the top 3 reviews first. When I get a chance, I'll go back and review the average and terrible :)
If money is no object, get the Darn Tough Vertex. If you're price sensitive, and willing to compromise a bit on quality, go with the PUMAs, which is what I did. Otherwise, these ASICS are near the same quality as the Darn Tough, but less expensive. Tough decisions :)

They fit perfectly
Size: X-Large, Color: Black
My favorite socks, the fit is great, they are comfortable and they are long enough so it covers my ankles, therefore, they don't rub against my inner shoe.
