Opening the valve at 65℃ (Stock 78℃).
Full opening at 75℃ (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 the ideal 75℃ to 85℃. As a result, it works toward preventing power loss, knocking, and various negative thermal effects and the engine will operate with the peak power.
The installation is an easy bolt-on regardless of the type of the radiator used from the stock to the fully tuned race car.
A must-have item for your high powered Honda.

Not to mention the great positive impact on a large capacity radiator, but it can also be significantly effective with a light modification set up like – stock radiator + low temperature thermostat + low temperature thermal switch + performance coolant.
With above mentioned light mod, the water temperature stays at around 80 ℃ on street driving.
