Acuity Super Cooler Reverse Flow Silicone Radiator Hoses | 2023+ Honda Civic Si & 2024+ Acura Base/A-Spec (1982)
Acuity InstrumentsSuper Cooler Reverse Flow Silicone Radiator Hoses for 2023+ Honda Civic Si & 2024+ Acura Base/A-Spec
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; ACUiTY engineers determined that the radiator can reject more heat if the water flow through it is reversed. This 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 3.6°F (2°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.
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 3.6°F (2°C) on cars already equipped with free-flowing grills, upgraded radiators, and vented hoods
- 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
Benefits
- Lowers radiator temperatures significantly while remaining impervious to high heats
- Use it before and after improving airflow, with the ability to run 1 degree cooler on an OEM setup this is an upgrade that will last through future modifications
- Superior, German-style hose clamps with rolled edges secure hoses in place much better than stock clamps without damaging them
