Mugen Low Temp Thermostat S2000 NSX 1999-2009 #19301-XGS-0000. Operating temperature: 68°C. Mugen Genuine Part, Made in Japan. F20C/F22C

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.

The use of a flow-control-type valve prevents hunting, thereby achieving rapid stabilization of the water temperature (the engine warms up within a short period). Operating temperature: 68°C (OEM: 76~80°C) Full-throttle acceleration temperature: 81°C (OEM: 90°C)
