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 under hood 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°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 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.
