It is similar to running an old carbureted vehicle with the choke all the time. Also, there truly is the possibility of ice formation in the TB during the colder months without this system. With the addition of an insulator, the vehicle can operate as it was meant to and the intake will remain cooler.

Im with him on that one. I ask autozone last year because I notice that the throttle body was hot from the coolant running through it. They said if you bypass the coolant from going to the throttle body that would make the car idle high b/c of temp sensors in the TB. And that also leading to more gas consumotion and might even trip a code, but the air would run cool before entering the intake manifold. LOL. Not something I would take a chance with. Unless you got an older car without the ECUs.
