Koyorad now produces a high quality direct replacement all aluminum performance radiator for the 2008-2017 Subaru WRX and WRX STI. This application features Koyorad’s VH-series radiator, 36mm core thickness with Hyper Fin and Tube Pitch design.

The Hyper V-Core Series is the newest to the Koyorad | Koyo All Aluminum Racing Radiator line up. An engine’s cooling system in many newer vehicles are suffering due to limited space and crowding which affects air circulation. Koyorad’s new ultra efficient Hyper V core was developed specifically for vehicles, which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design. The Hyper V Series radiators have a specially designed fin and tube pitch, which significantly increases its surface area while still allowing for excellent air circulation through the radiator. The Hyper V-Core series is the perfect solution where space savings and high performance is a must. Unless noted otherwise, all Koyorad Hyper V-Series All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans.

Note: STI w/ 8mm turbo return pipe: includes 2015 and 2016 Subaru STI. Optional coolant port has M14-1.25 thread.
