Acuity 22-24 Civic Si / 23-24 Integra Super-Cooler Reverse Flow Radiator Hoses Part Number: 1982

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. Each set comes with 2 silicone radiator hoses and 4 German-style hose clamps.
