Koyo Performance Radiator – Honda Civic Type R FL5 K20C1 MT 2022+

Application: Honda Civic Type R | 6BA-FL5 | K20C1 2.0L Turbo Petrol | Manual Transmission

Part Number: KH083967

The FL5 Civic Type R is Honda's most focused performance car in a generation — a 228kW turbocharged front-driver that holds lap records at circuits around the world. The K20C1 is a highly stressed engine that generates serious heat under sustained high-load driving, and with the FL5 increasingly popular on track days and time attack events, cooling performance matters more than ever.

Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the FL5, engineered to the same factory fit and mounting points as the OE unit. 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.
