Koyorad Performance Radiator - Honda NSX (NA1/NA2)
Koyorad has been building aluminium radiators for Japan's performance car scene for decades, and this core brings genuine cooling upgrade to the Honda NSX. Nocolok furnace brazed and hand TIG welded, it's engineered to hold coolant temperatures in check when the factory unit starts to struggle under sustained load.
This listing covers the Honda NSX, both NA1 and NA2 chassis, spanning C30A and C32B engine variants from 1990 to 2005. SKU V2032 / KV082303R is a direct bolt-in replacement using the OEM fan shroud mounts and hose connections, so no cutting or fabrication is needed.
Note: This radiator is designed for manual transmission (MT) NSX models only.
