Koyo Hyper V-Core Series Aluminum Racing Radiator Subaru WRX 2008-2014 / STi 2008-2021

The Koyorad Koyo Hyper V-Core Series is the latest addition to the All Aluminum Racing Radiator lineup. It was specifically engineered for vehicles facing extreme heat and limited space, which often leads to poor air circulation in the cooling system. With our new ultra efficient Hyper V core and specially designed fins and tubes, we have significantly increased surface area while still maintaining excellent air circulation.

This series is the ideal solution for those seeking both space savings and high performance. All Koyorad Hyper V-Series All Aluminum Radiators have been Nocolok brazed and are a perfect factory fit with no need for engine modifications. Additionally, they retain mounts for the stock fan shrouds and fans, making installation seamless.

Koyo radiators are very durable and are direct replacements for your factory intercooler.
