ACUiTY's Super-Cooler, Reverse-Flow Silicone Radiator Hoses can help your Civic or Integra to run cooler while using superior materials to help better deal with increased underhood temperatures. By reversing water flow through the radiator, these hoses actually help your Civic or Integra to cool itself more efficiently.

These hoses were developed as part of a project to help HRC (Honda Racing Corporation) cool their race cars more efficiently. They were also featured on the Team Honda Research FL5s that won 1st and 2nd in class at the 2024 running of the 25hrs of Thunderhill. Shortly after the release of the FK8 Civic Type R, ACUiTY engineers determined that Honda's K20C-equipped cars could reject more heat if the water flow through the radiator is reversed. Since the FL5 and DE5 share a very similar cooling pack, ACUiTY was able to port this discovery over to those platforms as well. The additional cooling achieved is due to how the intercooler rejects heat from charge air and how that heat flows through the lower part of the radiator. In very hot conditions on cars that also have upgrades like hood venting and an upgraded radiator, water temps were reduced by as much as an additional 4.5°F (2.5°C) after installing these hoses. On totally stock cars, temperature reduction is lower, close to 1°F (0.6°C) in hot conditions. In addition to this extra cooling power, the polyester-reinforced silicone construction helps the hoses handle temperatures up to 100°F hotter than the stock EPDM rubber hoses. As an added benefit, the kit includes German-style hose clamps that have formed threads and rolled edges to help protect your radiator hoses from the cutting damage that traditional hose clamps often cause on silicone hoses. Also included in the kit is hardware to relocate the ECT2 sensor for improved accuracy of cold-side temperature reading.

Below is an illustration that shows an approximation of the temperature gradient on the radiator with the stock water-flow direction and radiator hoses. Note how (in the stock configuration) the hotter part of the radiator (top) is where the cooler air coming through the top grille comes in, while the cooler, lower part of the radiator is where the hotter air exiting the intercooler passes through the radiator. Because the water exiting the radiator is nearly the same temperature as the air entering the bottom of the radiator, this setup can render the lower half of the radiator ineffective in hot climates.

Features

  • Polyester-reinforced silicone construction can handle up to 100°F higher underhood temps than OEM rubber hoses
  • Reverse-flow design aligns the radiator thermal gradient more ideally to help reduce water temps by up to an additional 4.5°F (2.5°C) on cars already equipped with free-flowing grills, upgraded radiators, and vented hoods.
  • Includes hardware to relocate ECT2 for more accurate water temperature readings
  • Includes superior, German-style hose clamps with rolled edges to safely and securely hold both hoses in place

Fits:

  • 2023+ Honda Civic Type R (11th Gen, FL5)
  • 2024+ Acura Integra Type S (5th Gen, DE5)

I love this comforter! It is so silky soft, feels so nice to sleep under.
Size: King(103“*90”), Color: Luxury Grey, Size: King(103“*90”), Color: Luxury Grey
I absolutely love this comforter! It is super lightweight and has a very silky soft shell on both sides. It feels so good to sleep under! Ever since I have been using it, I haven't been waking up in sweat covered sheets. It constantly has a cool feel to it 24/7. It is large enough that it fits my king size bed pretty good. It doesn't hang far over the edges, but it fits. It is dual sided, so you can have a light gray look on one side and a dark gray look on the other side, depending on what fits your decor better. I definitely recommend getting if you are on the lookout for a cooling comforter, especially because of the silky soft feel.

It really cools - Extremely soft - Not too heavy
Size: Queen (90" * 90"), Color: Luxury Grey, Size: Queen (90" * 90"), Color: Luxury Grey
This comforter arrived packaged very well from the manufacturer. It arrived sealed in plastic inside a box. The color and appearance of the comforter received looks like what was shown in the listing. This comforter is extremely soft. It feels very cool to the touch. It has a great cooling effect. It is also not too heavy. A lot of cooling bedding products like this feel heavy. While this does have some weight it is not too much. It is easy to move around. The comforter is easy to refresh and cool off again after extended use. I just uncovered myself, lifted and moved the comforter around a little, then covered back up. This made it feel cooler again. I am very happy with this comforter so far. I like the color and design. I really like feeling cool when falling asleep. This will be great when the temperatures start going up. I will update this review later if anything changes after washing a few more times and longer use. I think this will be a good comforter for most hot sleepers who like to cover up all year.

Feels seriously amazing!
Size: Twin(90“ * 67”), Color: Luxury Grey
This is my second cooling comforter from this brand and this one is just as amazing as the first. It’s silky soft and makes a significant temperature difference. It’s like magic; you don’t need to do anything special to cool it before bed. If you do want extra coolness, you can place it in front of your AC or turn on your fan for a little bit before bed and It absorbs the extra coolness but either way it lasts all night. I use it with the cooling pillow, and the hot summer nights are no match. It’s easy to wash, really silky, smooth, and actually cool against the skin. It also somehow has a weighted blanket-like feel without being heavy. I standby this blanket so much that this is my second one, highly recommend!

Super Soft, Lightweight, and Surprisingly Cozy
This ended up being so much better than I expected. The first thing I noticed is how incredibly soft it is - it has that plush, velvety feel that makes you want to keep reaching for it all day. It’s lightweight but still warm, which I really like. It gives you that cozy, wrapped-up feeling without being heavy or overwhelming, so it works well for everyday use on the couch or even for sleeping. For reference, I’m 5’2” and it’s big enough to comfortably use as a full snuggle blanket. It also looks really nice draped over furniture. The texture adds a little dimension, and the clean, simple color gives it a polished look that doesn’t feel cheap. One thing to note is that it arrives compressed, but it fluffs up nicely once opened and feels much fuller after a little time. The only thing to keep in mind is that lighter colors will naturally show dirt more easily, so that’s something to be aware of with regular use. Overall, this has easily become my go-to daily throw - soft, comfortable, and much nicer than I expected for the price.

luxury fleece throw blanket ribbed plush texture cozy aesthetic blanket
This is one of those blankets that instantly makes a space feel more cozy and put together. The first thing that stands out is the texture. It has that plush, ribbed look that’s been really popular lately, very similar to those oversized lounge chairs and couches with the same soft, fluffy pattern. It looks especially good draped over furniture and adds a nice aesthetic touch instead of just being functional. It’s also genuinely soft and comfortable. The fleece has that “cloud-like” feel without being heavy or stiff, and it’s warm enough for everyday use without feeling overly thick. The size at 50 x 60 inches is great for lounging, whether you’re watching TV or just relaxing. I really appreciated how it was packaged. Instead of being secured with a bunch of plastic fasteners, it was simply wrapped with a ribbon, which made it easy to open and avoided the usual hassle of cutting out plastic tags. It also arrived vacuum sealed and had no odor at all, so it was ready to use right away. They even included a full-color instruction card, which was honestly a nice touch. It goes over care and even styling ideas, which adds to the overall presentation and makes it feel more polished. For the price, this feels like a great value. It looks good, feels good, and works well both as a functional blanket and as part of your home decor.
