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.
