Koyo Performance Radiator – Subaru WRX VB FA24 2022+
Application: Subaru WRX | VB Chassis | FA24F 2.4L Turbo Petrol AWD
Part Number: VH093890 / KV093890
The VB WRX is the most capable WRX ever built — a purpose-engineered sports sedan with the new FA24F 2.4L turbocharged boxer, a significantly stiffer chassis, and a suspension setup that rewards committed driving. The FA24F generates more heat than the EJ it replaced, and with the VB increasingly popular on track and in performance builds, keeping coolant temperatures stable is key to consistent performance under load.
Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the VB WRX, 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.
