The purpose of this product is to maintain the maximum horsepower by keeping the temperature of the cooling water at around 75℃ – 80℃. It activates the fan at 80 instead of 95 and fully utilizes the water characteristics of high specific heat (Water changes temperature slowly for both upward and downward). As a result, it works toward preventing power loss, knocking, and various thermal negative effects. It works well for all types of cooling system from the stock radiator to a multi layer racing radiator.
