Koyo's aluminum radiators for the Scion FR-S/Subaru BRZ are designed to keep your engine cool even under some of the harshest conditions. Koyo radiators are made from light weight aluminum and are made for street and track use.
Koyo is Japans largest aftermarket radiator manufacturer, utilizing the latest aircraft quality aluminum and Heli-arc welded. Heli-arc soldering is the highest quality standard for enforcement along aluminum connections.
Koyo uses a fin and tube pitch which significantly increases its surface area while still allowing for excellent air circulation through the radiator. All of their racing radiators for the BRZ/FR-S are Nocolok brazed and are made as a direct bolt in with no engine modifications necessary. They retain mounts for the stock fan shrouds and fans as well.
