Koyorad Aluminium Racing Radiator – Nissan Skyline GTS-T / GT-R R32 / Cefiro A31

Koyorad aluminium racing radiators are a direct factory-replacement upgrade, built to handle increased cooling demands on modified and track-driven vehicles. The thicker 48mm Hyper Core and high-efficiency fin design provide improved coolant flow and a larger temperature drop across the surface compared to the standard radiator.

Koyorad is Japan’s largest aftermarket radiator manufacturer, using aircraft-grade aluminium and precision Heli-arc welding for strength and durability. All radiators are built to OE-specific dimensions for an easy, direct fit.
