Vehicle / Engine Application: 2017+ Civic Type R K20C1 (FK8)
The newly developed FK8 Spoon low-temp thermostat has a valve opening temperature of 68°C (OEM 78°C) and a fully open temperature of 81°C (OEM 90°C), which is about 10°C lower than the standard OEM thermostat. Cooling water circulates quickly through the radiator, and cooling is started before the water temperature rises, thereby suppressing power down.
This thermostat has the operating temperature set lower than normal. It prevents engine power loss by minimizing rapid water-temperature rises under harsh conditions such as during circuit driving.
