But I plan to bypass the coolant passage in my throttlebody?

Outlaw Engineering does not feel that bypassing the throttlebody coolant passage is a very elegant solution to throttlebody heat. This often leads to rough idle, increased fuel consumption and possibly higher emissions. Many TB's contain thermosensors that would never reach operating temperature. 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.



Bold is mine.

The TB is heated by engine coolant to prevent ICE. So intake air is pretty cold leaving the TB.

My intake, when the engine is running, is never 135 degrees above ambient (AS on dyno chart). That would be 185 degrees on a 50 degree day, or 225 on an 80 degree day. I mentioned the refrigeration effect of reducing the pressure of the air. They talk about running cooler than ssay don't remove throttle body heating as the intake will ice up. So they are keeping it cool, but heating it. Why does the Car Mfg. heat the TB? So it doesn't ice up under NORMAL conditions. Sounds like a real heat problem huh?

We need a graemlin for "talking out both sides of mouth"

So, if you put spacers in, you should heat the TB. hahaha
