Description
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.
Why Koyorad?
- Precise Tube & Fin Alignment - Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
- Nocolok Furnace Brazing - All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
- Billet Filler Neck - Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
- OE-Specific Mounting - Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
- Hand-Crafted Heliarc Welds - Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
