ACUiTY's Super-Cooler, Reverse-Flow Silicone Radiator Hoses can help your FK8 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 FK8 to cool itself more efficiently.

While investigating the overheating issue that affects FK8's in hot conditions, 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 4.5 degrees F (2.5 degrees C) after installing these hoses. On totally stock cars, temperature reduction is lower, close to 1 degrees F (0.6 degrees C) in hot conditions. In addition to this extra cooling power, the polyester-reinforced silicone construction helps the hoses to handle up to 100F hotter temperatures 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.

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 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.

Features:
-Polyester-reinforced silicone construction can handle up to 100F higher underhood temps than OEM rubber hoses
-Reverse-flow design aligns radiator thermal gradient more ideally to help dissipate more heat in demanding conditions
-Tested to reduce water temps by up to an additional 4.5 degrees F (2.5 degrees C) on cars already equipped with free-flowing grills, upgraded radiator, and vented hoods
-Includes superior, German-style hose clamps with rolled edges to safely and securely hold both hoses in place
