By lowering the operating temperature, it has the effect of cooling quickly and minimizing power loss. It can be used with both genuine radiators and aluminum radiators.
This is an essential part for engine tuning cars. The opening temperature can be set to 68℃ (genuine 78℃) and the full opening temperature to 81℃ (genuine 90℃), approximately 10℃ lower than the genuine thermostat.
CIVIC FL1 Low Temp Thermostat
The low-temperature thermostat has an opening temperature of 68°C (stock: 78°C) and a fully open temperature of 81°C (stock: 90°C), which is approximately 10°C lower than the stock thermostat.

■A water temperature of around 70 to 80°C is the range that maximizes engine power.
■If it rises any higher, a sudden drop in power will occur.
■As the water temperature rises, knocking symptoms will occur in the combustion chamber and the ECU will increase the amount of fuel and retard the ignition timing.
■The valve opening temperature is reduced from the stock 90°C to 81°C.
■At the same time, measures to lower the water temperature are also necessary, such as a large-capacity aluminum radiator, an opening in the bumper to increase air flow, and an outlet structure in the bonnet.
