Mishimoto's Secondary Race Radiator kit for 2017–2021 Honda Civic Type R (FK8) adds a compact heat exchanger mounted behind the K20C1 engine to supplement the factory cooling system. Tapping into the coolant circuit after the heater core and using factory airflow, it increases cooling capacity and coolant volume to help prevent overheating on track or spirited driving. The kit is full aluminum with TIG-welded end tanks and includes Mishimoto's lifetime warranty.
