Koyorad Hyper V-Series Aluminium Racing Radiator - Subaru Impreza WRX / WRX STI (GC8/GF8)

Upgrade your Subaru Impreza WRX or WRX STI's cooling system with the Koyorad Hyper V-Series all-aluminium racing radiator, designed and built in Japan by one of the most respected names in performance cooling. Koyorad has been supplying OEM and motorsport cooling solutions for decades, with the Hyper V-Series representing the latest evolution of their all-aluminium racing radiator line-up.

The Hyper V-Core 36mm design was developed specifically for vehicles operating under extreme thermal load in space-constrained engine bays. The specially designed fin and tube pitch significantly increases internal surface area while maintaining excellent air circulation through the core, delivering substantially improved cooling capacity over the standard OEM unit. This is a direct bolt-in upgrade that retains the factory fan shrouds, fans, inlet/outlet locations, and top/bottom mounting pins.
