Koyo Performance Radiator – Subaru Impreza GC8 / Legacy / Liberty MT 1989–2000
Application: Subaru Impreza WRX/STI (GC8) / Legacy / Liberty (BC5/BD5/BF5/BG5) | EJ20 Petrol AWD | Manual Transmission
Part Number: VH090302 / KV090302
The GC8 Impreza WRX and STI are among the most iconic performance cars ever built — lightweight, turbocharged, and with a motorsport pedigree that spans WRC championships and countless grassroots rally and circuit builds. The Legacy and Liberty of the same era share the same EJ20 platform and are equally popular for performance builds. Keeping coolant temperatures stable is fundamental to getting the most out of these engines under sustained load.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade across the GC8 and BC/BD/BF/BG Legacy platform, engineered to the same factory fit and mounting points as the OE unit. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.
