ACUITY Super-Cooler Reverse-Flow Radiator Hoses - Honda Civic Type R (FK8)
The ACUITY Super-Cooler Radiator Hoses reverse the coolant flow through the FK8 Civic Type R's radiator. ACUITY developed them while looking into the FK8's tendency to run hot. In the factory layout, the coolest part of the radiator sits behind the intercooler, where the incoming air is already hot. Reversing the flow puts the hottest coolant where the air is hottest and the coolest coolant where fresh air from the upper grille arrives.

How reverse-flow hoses help the FK8 Civic Type R run cooler
Installing the 1936 Super-Cooler radiator hoses on an FK8 Civic Type R
ACUITY measured up to 2.5°C lower water temperatures on hot days in cars that already had a vented bonnet, upgraded radiator and free-flowing grille, and around 0.6°C on otherwise stock cars. The hoses are polyester-reinforced silicone that handles much higher underbonnet temperatures than the factory rubber hoses.
Note: Suits the FK8 Civic Type R. Installation by a professional is recommended.
