Koyo Performance Radiator – Subaru Impreza WRX / Legacy / Liberty MT 1998+
Application: Subaru Impreza WRX / Legacy / Legacy Wagon / Liberty | EJ20T / EJ20 Turbo Petrol AWD | Manual Transmission
Part Number: VH090866 / KV090866
The BE/BH Legacy and GD Impreza WRX share the same proven EJ20 turbocharged boxer platform — a capable, tuneable engine that rewards modification and performs well under sustained load. Whether it's a daily driver, a touring build, or a performance street car, keeping coolant temperatures stable is fundamental to getting the most out of these engines.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade across the BE5, BH5, and Impreza WRX platforms, 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.
