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.

Why Koyorad?

  • Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
  • Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
  • Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
  • OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
  • Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
