FITS:

  • 11th Gen Honda Civic Type-R
  • 5th Gen Acura Integra Type-S

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.

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.

In contrast, below is an illustration that shows an approximation of the temperature gradient on the same radiator with ACUiTY's Super-Cooler hoses. By flipping the flow through the radiator, the hotter water is at the bottom, being cooled by the hot air exiting the intercooler, and the colder water exits out the top, where cool air passes through the radiator after entering through the upper grille. This reversed flow more ideally aligns the radiator thermal gradient with the thermal gradient of the air passing through the radiator which helps the radiator to dissipate heat more effectively.

How fast is shipping?

Most orders placed on a weekday before 1pm EST will ship out the same day. Otherwise, it is common for parts to ship in 2-3 days from order date. Please note that both of these exclude special order items, which are clearly marked on product pages.

What is the returns policy?

Most products sold by Axion Industries LLC are covered by our Standard Return Policy and may be returned within 30 days of the original invoice date for a refund. Please note that a restocking fee will apply (see "Refunds Policy" in FAQ).

All returns require written approval from Axion Industries LLC. Original Shipping and return shipping charges are strictly non-refundable. For more information regarding our shipping refund policy, please refer to the "Refunds Policy" on FAQ.

Does it come with a warranty?

Axion Industries LLC does not offer any type of warranty coverage for defective products except those that are manufactured by us. However, the majority of the products available through our website are covered separately under a manufacturer's warranty.

If you recently purchased a product from Axion Industries LLC and are concerned about the fitment or performance of your item, please contact us for assistance.

Our customer service representatives can provide limited support, advice, and assistance identifying the possibility of any manufacturer defects. If we suspect your product does have serious defects, our customer service department can serve as a contact with the manufacturer to help arrange a warranty inspection and, if applicable, any necessary repairs or replacement shipments.

If you wish, you may also contact the manufacturer directly for information regarding product eligibility and specific terms and conditions of warranty coverage.

What happens if I want to cancel?

Unfulfilled, cancelled orders will require a 10%-30% cancellation fee unless you choose store credit (a 5%-15% cancellation fee will apply in this case). This fee is to:

  1. Recover the processing fees for both the order you placed and the order
    you canceled.
  2. Cancellation fees imposed by the manufacturer, should the part be coming
    straight from them. OR
  3. Restocking fees, since the part now has to be resold.

The following may NOT be canceled:

  • Orders that are already fulfilled – the Returns Policy will apply.
  • Pre-orders - the Returns Policy will apply.
  • Special Order items that were approved for sourcing by the customer.
  • Items that are on sale and labeled "final sale" during that sale period.

Please see "Order Cancellation" under FAQ for more.
