Koyo Performance Radiator – Honda S2000 AP1 F20C MT (1999–2009)

Application: Honda S2000 MT | GH-AP1 | F20C | Manual Transmission

Part Number: KV081226U06/ VH081226

When you're pushing an S2000 hard — whether it's a weekend track day or a spirited mountain run — the last thing you want is your cooling system holding you back. The Koyorad KV081226U06 is a direct bolt-in performance upgrade engineered specifically for the AP1 S2000, delivering improved cooling capacity without any cutting, drilling, or fabrication.

Koyorad's all-aluminium construction and high-efficiency 36mm 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.
