Throttle Body


Can anyone tell me what this part is called that attaches to the bottom of the throttle body? Where can I find one?

Re: Throttle Body
It's the IAC housing with a passage for coolant to warm the throttle body up. Bypassing that coolant passage is a common mod to help keep the incoming air cooler.
