Koyo Performance Radiator – Honda Civic Type R FK8 K20C MT 2017–2021
Application: Honda Civic Type R | FK8 | K20C 2.0L Turbo Petrol | Manual Transmission
Part Number: KH083417
The FK8 Civic Type R redefined what a front-wheel-drive performance car could be — a 228kW turbocharged machine that set lap records at the Nürburgring and became the benchmark for hot hatches worldwide. The K20C is a highly stressed engine that generates serious heat under sustained high-load driving, and with the FK8 a firm favourite 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 FK8, 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.
