Koyo Performance Radiator – Honda NSX NA1 / NA2 (1990–2005)
Application: Honda NSX MT | NA1 / NA2 | C30A / C32B | 1990–2005
Part Number: KV082303R | V2032
The Honda NSX is one of the most iconic Japanese sports cars ever built — a mid-engined, aluminium-bodied masterpiece that redefined what a supercar could be. Whether you're preserving a concours example or pushing your NSX hard on track, the factory radiator can become a limiting factor under sustained high-load conditions. The Koyorad KV082303R is a direct bolt-in performance upgrade engineered specifically for the NA1 and NA2 NSX, delivering improved cooling capacity without any cutting, drilling, or fabrication.
Koyorad's all-aluminium construction and high-efficiency core design dissipate heat faster and more effectively than the factory unit, keeping coolant temperatures in check even under sustained high-load driving. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.
