Acuity's Super Cooler Reverse Flow Silicone Radiator Hoses can help your Honda Civic FK8 run cooler while using superior materials to help better handle increased under-bonnet temperatures. By reversing the water flow through the radiator, these hoses can help your FK8 to cool itself more efficiently.
While investigating the overheating issue that affects FK8s, Acuity engineers found that the radiator can dissipate more heat if the water flow is reversed. This is due to how the intercooler leaves heat from charged air and how that flows through the lower part of the radiator.
In scorching conditions on cars with upgrades like bonnet vents and an upgraded aftermarket radiator, water temperatures were reduced by as much as 4.5°F (2.5°C) after installing these silicone hoses. On factory cars, temperature reduction is lower, closer to 1°F (0.6°C) in hotter conditions.
In addition to this extra cooling, the reinforced silicone helps the hoses to handle up to 100°F hotter than the stock rubber hoses. As an added benefit, the kit includes German-style hose clamps with formed threads and rolled edges to protect your radiator hoses from cutting damage that traditional hose clamps cause on silicone hoses.
Each set comes with two silicone radiator hoses and 4 German-style hose clamps.
The photos above illustrate an approximate temperature gradient on the radiator with the stock water-flow direction radiator hoses. Note how the hotter part of the radiator is where the cooler air coming through the top grille comes in, while the cooler, the lower part of the radiator, is where the hotter air exiting the intercooler passes through the radiator.
Because the water leaving the radiator is nearly the same temperature as the air entering the bottom, this setup can render the lower half of the radiator ineffective in hot climates.
