Radiator Subaru 08-14 Impreza WRX / STI Black

The CSF Radiator for 2008–2014 Subaru Impreza WRX and STI in black is a direct-fit aluminum cooling core engineered to manage the high heat output of turbocharged flat-four engines. This single-pass radiator features a top-center inlet and driver-side outlet configuration that integrates seamlessly into OEM cooling systems, making it a straightforward replacement for worn or damaged factory units.

Measuring 27.125 inches wide by 13.375 inches tall with a 1.625-inch core depth, this radiator is constructed from aluminum with a black powder-coat finish that resists corrosion and matches modern engine bay aesthetics. The single-pass design optimizes coolant flow efficiency, critical for WRX and STI platforms where sustained boost pressure and aggressive driving conditions demand reliable thermal management. The specific inlet/outlet positioning ensures proper flow direction through the cooling system without modification to existing hose routing.

This radiator is purpose-built for Subaru turbocharged enthusiasts who require OEM-equivalent cooling performance without compromise. Whether addressing overheating issues during track sessions, replacing factory radiators weakened by age, or upgrading before modified engine work, this CSF unit delivers the cooling capacity stock WRX and STI owners depend on. The black finish integrates seamlessly with both stock and modified engine bays, while the aluminum construction balances weight savings with durability.

CSF Cooling specializes in performance radiators for import performance vehicles, and this model reflects their focus on direct-fit OEM replacement solutions. Installation requires no modifications to factory mounting points or plumbing, making it accessible to owners performing their own maintenance or relying on professional shops familiar with Subaru cooling systems.
