Koyo Performance Radiator – Subaru Impreza WRX / STI GDA / GDB / GDF / GGA 2002–2007

Application: Subaru Impreza WRX / WRX STI | GDA / GDB / GDF / GGA | EJ205 / EJ207 / EJ255 / EJ257 Turbo Petrol AWD | 4AT / 5MT / 6MT

Part Number: VH091672 / KV091672R


The GD-series Impreza WRX and STI are among the most popular and enduring performance platforms in Australia. Whether it's a street build, a rally car, or a track weapon, 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 GDA, GDB, GDF, and GGA Impreza platform. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — retains all OEM fan shroud mounts and stock hose connections with no modifications required.


Why Koyorad?

  • Precise Tube & Fin Alignment — Optimal coolant flow and maximum heat transfer efficiency.
  • Nocolok Furnace Brazing — All components bonded as one unit for vibration and debris resistance.
  • Billet Filler Neck — Precision-machined for strength, durability, and a reliable seal.
  • OE-Specific Mounting — Retains factory fan shroud, hose positions, and mounting pins.
  • Hand-Crafted Heliarc Welds — Individually welded for the strongest possible aluminium-to-aluminium bond.
