The KOYO R-Core all aluminum radiator is the absolute BEST high-performance radiator you can buy for your MK4-JZA80 Toyota Supra. The KOYO radiator fits similar to stock and has a robust 53mm all aluminum Nocolok brazed core. Stock fan shroud mounts make installation a breeze. This radiator is designed to fit the JZA80 Supra chassis with either manual/automatic transmission and turbo/non-turbo applications. Supras with automatic transmissions will require a separate transmission cooler. Engine swaps may require slight tweaking to help fit radiator hoses.
