Take control over your engine coolant temps by changing to a lower temp thermostat. These thermostats open at a lower temperature than your stock thermostat, getting your hot coolant to the radiator sooner. This is an important modification to make on any engine making more power than stock, from a cam only setup all the way into supercharged build. We offer both 160 and 180 degree options to fine tune your cooling system to your own needs.
