It reroutes the engine coolant so that it doesn't enter the throttle body. Therefore keeping the TB cool. Colder, denser air equals more horsepower. Although it isn't a significant gain, every little bit helps. Check the tech articles on instructions on how to do it. Cheap, easy, well worth it mod in my opinion!
