Fits 2003-2007 Subaru Impreza WRX, WRX Limited, WRX TR, WRX STI, and WRX STI Limited models equipped with a manual transmission.

The Koyo VH091672 is a high-performance, all-aluminum radiator designed to replace the fragile plastic-tank factory unit in the Subaru GD chassis. This specific model features an integrated filler neck, making it the correct choice for the cooling system configuration found in early 2003-2007 Impreza WRX and STI models. Engineered for a drop-in installation, it utilizes factory mounting points and is compatible with OEM fan shrouds and hoses.

  • All-Aluminum Construction: Precision TIG-welded tanks and a high-density core provide superior durability and heat dissipation compared to OE crimped-plastic radiators.
  • Nocolok Brazing: Manufactured using a state-of-the-art brazing process to ensure core strength and leak-free performance under pressure.
  • Direct Fitment: Designed to install without modifications, accepting all factory sensors and hardware.
  • Application Specific: Engineered exclusively for Manual Transmission (MT) models requiring a radiator-mounted fill point.
  • Part Number: VH091672
