The Koyo performance lightweight aluminum radiator is specifically designed and built for the WRX and STi. Koyo doesn't use universal fit parts to create their radiators so you can rest assure this upgraded system will fit without any modification for easy installation. Mounting brackets allow for the use of the stock fans, eliminating the need to purchase an aftermarket fan. Polished to a near chrome finish, this radiator enhances the engine compartment of a 'show' destined Subaru WRX/STi. Koyo radiators use an aluminum core, even the end-tanks are made of aluminum, cores are NOCOLOK-brazed.Overall expect this upgraded Koyo performance radiator to provide your Subaru WRX with 20-30% more cooling than any standard radiator and also have the capabilities of handling a high revving, high performance motor.
