DC5 Lower Temperature Thermal Switch
Parts# STW-T5 Price $69.00

Activates the cooling fan at 80C (stock 95C). Stops the cooling fan at 75C (stock 90C).

When the cooling water temperature reaches a certain point, in order to avoid possible risks, the ECU will make several changes including fuel increase and retarding the ignition point which will cause a reduction of power. The purpose of this product is to maintain the maximum horsepower by keeping the temperature of the cooling water at around 75C – 80C. It will activate the fan at 80C instead of 95C and fully utilizes the water characteristics of high specific heat. (Water changes temperature less when it is absorbed or loses a given amount of heat). As a result, it works toward preventing power loss, knocking and various thermal negative effects. It works well for all types cooling systems from the stock radiator to multi layer racing radiators.

DC5 Lower Temperature Thermostat
Parts# STT-T5 Price $140.00

Opening the valve at 68C (stock 78C). Full opening at 83C (stock 90C).

Like a lower temperature thermal switch, the thermostat helps maintain optimal water temperatures for maximum performance. The thermostat sets the valve’s opening temperature lower than the stock to circulate the coolant earlier in order to maintain the temperature at around 75C-85C. As a result, it works toward preventing power loss, knocking and various negative thermal effects. It works well for all types cooling systems from the stock radiator to multi layer racing radiators.

J’s Racing recommends use of this product in combination with the lower temperature thermal switch.
