A very popular upgrade for track cars. By replacing your original 92 degree thermostat with a 80 degree thermostat, you are allowing the coolant to enter the radiator sooner, causing your engine to run cooler. Many high horsepower cars or track day cars are constantly in the higher rpm band for longer periods of time. Because of this, the engine can run hotter in some climates. This lower degree thermostat will help out this situation. Includes gasket.
Fitment: M44, M50, M52, S50, S52
