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)

Great stuff!
Color: #3 Rose Gold
Trying to give 4.5 stars. It’s phenomenal! My only .5 is that is absolutely does rub off on clothing. I’m going to a party tomorrow and I’ll try using setting spray after application. I love it though. Light weight, no odor and shimmer you can use on body, hair and even accessories!

Beautiful, Subtle, Long Lasting Sparkle
Color: #3 Rose Gold
Sprays easily and seems long lasting, (stayed on for more than 3 hours of light household work). The glitter is very fine, and that’s exactly what I wanted, it is not visible dots or shapes- my arms just sparkled when I moved them and with the changing light. Feels like nothing is there. Nice! Doesn’t feel especially moisturizing, but hasn’t dried my skin out either.

Great to have this on hand
Color: #3 Rose Gold
I bought the rose gold to add some shimmer to my body and hair. It's the right amount of shimmer to stand out. Looks super cute, it sticks easily and when you wash it off, the glitter comes off easily. The smell isn't the best, but it isn't terrible. I just use my own fragrance after I put this on. I love the glow it gives my skin and the shimmer it gives my hair. I'm going to buy this product again. Second time buying this and I love it!
