HYPER KH Series 25mm Core
Koyorad’s new “KH Series” radiators feature high density 25mm cores. Koyorad’s radiator design and selection of materials results in the most effective and efficient means of heat extraction while also allowing proper air circulation through the engine bay. Koyorad was able to increase coolant volume while keeping overall weight to a minimum. In typical fashion, Koyorad has engineered this radiator with precision, directly replacing the stock OEM plastic/aluminum radiator and will bolt easily to the factory equipped fan shroud for a quick and simple installation. Get every ounce of cooling efficiency from your Koyo all aluminum performance radiators with a genuine Koyorad Hyper Cap, Sold Separately. Drain Plug is included.

Koyorad’s superior quality, precision hand welds, reliability and uniformity are what have earned Koyorad their excellent reputation in performance cooling worldwide. This performance aluminum radiator is the perfect solution where space savings and high performance is a must!
 

Features:

  • Precise Tube and Fin Alignment: Construction under strict quality control and solid boxing result in tubes with optimal coolant flow and fins with highly efficient heat transfer.
  • Nocolok Brazing: Tubes, Fins, Headers and Brackets are brazed in a state-of-the-art Nocolok furnace, bonding all components to resist damage from vibration, road debris, and the elements.
  • Billet Filler Neck: Precision machined billet filler necks are incorporated on each Koyo radiator for strength, durability and better sealing.

  • Hand Crafted Heliarc Welds: Each Koyo Alloy Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminium to aluminium bond to mate all components.

THESE THINGS SHED BAD!!!!!!!!!
Color: Pink Strawberries, Size: Regular
These things shed like you wouldn't believe. They're all over my furniture, my floor, my clothes. I'm finding little pink pieces of sock fluff everywhere and it's annoying. I don't think they did that until after I washed them. So if they don't shed on you right away, just wait, it'll most definitely happen. I returned because I won't where them again.

Keeping the crusty heels at bay!
Color: Cotton Gray, Size: Regular
I deal with chronic dry heels that crack if left unmanaged. I bought these in hopes that when I do soak and scrub my heels that I can keep the cracking at bay. These have been a godsend. I wear them every night and my heels are nice and soft. I plan on purchasing more. A couple of things I have noticed, if I wear these during the day, the bottom of my feet do seem to sweat and there is some slipping. I have only washed these are directed (hand washing) and you will want to after a couple washes because it could give a sweaty feet smell. Overall, I highly recommend.

Moisturized heels out of the box
Color: Fuzzy Lilac Purple, Size: Regular
Work without adding anything to your feet, but there are extra nice if you wanted to add a moisturizer to you heel and not get it all over your socks. Worth the money!

A Staple in Skin Care Routine
Style: Milky Toner
This toner has become a staple in my skincare routine. I have sensitive skin and a lot of products tend to cause irritation or redness, but this one has been incredibly gentle from the start. My skin always feels soft, calm, and hydrated after using it. The texture is lightweight with an almost soapy feel at first, but it absorbs quickly and never leaves my skin feeling greasy or heavy. It layers well with the rest of my skincare and works great both morning and night. I also appreciate that it gives results similar to more expensive brands without the high price tag. Definitely one of the better affordable skincare products I’ve tried.

My Favorite Product in the Milky Line
Style: Milky Toner, Style: Milky Toner
This toner has easily become my favorite product from Thayers brand and all other brands. I’m very picky about my skincare routine, especially when it comes to products I use daily, and this one has completely earned a permanent spot in my routine. It feels incredibly gentle, hydrating, and soothing on the skin without feeling sticky or heavy. I love the ingredients, especially the snow mushroom and hyaluronic acid, because my skin always feels soft, balanced, and refreshed after using it. I’ve also noticed my pores looking smoother and overall healthier since incorporating this toner consistently. The formula works beautifully with the rest of the Milky line, and my skin genuinely looks and feels better when I use it regularly. I’ll absolutely continue repurchasing this product.
