Koyo Performance Radiator - Nissan 370Z (Z34) / Infiniti G Series (V36) / Q60 (V36) - Manual Transmission
Koyorad builds all-aluminium radiators using Nocolok furnace brazing and hand laid Heliarc welds, giving the core the strength to handle sustained track heat. This unit is a direct bolt-in upgrade for the Nissan 370Z and its Infiniti siblings, built to OE mounting points with a billet filler neck for a reliable seal under pressure.
This listing covers the Nissan 370Z (Z34), Infiniti G Series (V36) and Infiniti Q60 (V36), spanning the VQ37VHR, VQ35HR and VQ25HR V6 petrol engines, all fitted with a manual transmission.
