Opening the valve at 68 ℃ (Stock 78 ℃)   Full opening at 83 ℃ (Stock 90 ℃)


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.


The installation is an easy bolt-on regardless of the type of radiator used.


A must-have item for Honda with high power for all driving stages
