Koyo OEM Replacement Radiator Automatic Transmission 2003-2007 WRX

Koyo leads the radiator industry in quality, performance and fitment. Koyo engineers carefully design the radiators offering a true plug and play installation: No drilling, cutting, relocating, or stretching to get their radiators to fit properly. 

These OEM Koyo replacement radiators feature plastic end tanks with a aluminum core, allowing for a cost effective option compared to the OEM units.

This radiator is meant for cars with the automatic transmission with the filler neck on the radiator.

Early model WRX owners need to verify that their stock radiator has a radiator cap. WRX models without a radiator cap need the 2002 WRX radiator.
