Description
Koyo aluminum racing radiators are designed to be direct factory replacement units. Koyo racing radiator features a much thicker core with a more efficient fin design that helps with flow and temperature drop over the surface.
Koyo is Japans largest aftermarket radiator manufacturer, utilizing the latest aircraft quality aluminium and Heli-arc welded. Heli-arc soldering is the highest quality standard for enforcement along aluminium connections.
Upper radiator hose may require trimming for proper clearance.
Early model WRX owners need to verify that their stock radiator has a radiator cap. WRX models without a radiator cap need the 01-02 WRX radiator.
