Features NISMO Low-Temp Thermostat allows the radiator valve to achieve a lower temperature opening at 62℃ (Standard = 76.5℃). This promotes earlier coolant circulation inside the engine, reducing the power loss caused by rising coolant temperature during high speed driving at a racetrack. The valve opening temperature is set lower to within the vicinity of the threshold valve where a rich mixture boost for a low temperature condition would be triggered. Product Warning When the air temperature is low, such as during winter, the temperature of the water within the engine will not quickly rise, resulting in reduced interior heater performance.

This actuates in 68dgrees and full open in 82degrees.

Opening the valve at 68c (Stock 78c) Full opening at 83c (Stock 90c). All Honda vehicles with high power motor maintain a delicate relationship between the water temperature and the engine power. When the radiator water temperature starts rising, the ECU automatically reduces the risk (Map correction mode) by increasing the fuel and retarding the ignition timing, which results in losing power. This thermostat sets the valve’s opening temperature lower than the stock to circulate the coolant earlier and to maintain the temperature at around 75℃ to 85 ℃. As a result, it works toward preventing power loss, knocking and various negative thermal effects.
