In Honda vehicles with high-power engines, water temperature and engine power are closely related, and when the water temperature rises, the ECU takes measures to avoid crises (correction MAP) such as increasing fuel volume and delaying ignition timing, and a sudden power reduction begins.

This product sets the valve opening temperature (the temperature at which the main valve (sluice gate) "starts to open") lower than the normal thermostat, and circulates the cooling water to the radiator early, so that the water temperature can be set around the ideal 75°C ~ 85°C at all times, suppressing and preventing power down, heat dripping, and knocking. It will be possible to extract the original engine power.
