Acuity Super-Cooler Reverse-Flow Radiator Hoses Honda Civic Type-R FL5 23+
- 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.
