Intake tube.

[mental_help]

What does this part of my intake tube go to?

i kinda wondered the same.....maybe a vaccume line or something to heat the air that flows in.... i know my old dodge had a thing to bring in heat from the headers.

i don't know what that came off of but like he said, probably by the exhaust manifold...

i am kinda worried about it because it looks important.

wellmaybe tomorrow ill dig around and look to see what it goes to im pretty sure its to heat the air but when i bought my explorer it had a cold air on it and looks like they kept part of the stock airbox because they were confused...

did you take the intake tube off?

It goes to the shroud on the pass side engine manifold.

Thanks every one for the help.

It isn't important... to get slightly better mileage when an engine is cold the system will use heated air from the exhaust manifold as indicated by SuRrEaLNJ. Once the engine reaches its operational temp it will then pull in cold air from the inlet that mounts behind the front bumper. Switching from warm to cold air is controlled by the Bi-metal vacuum sensor located inside the stock air box.

Anyway as schmidlkofer indicated the warm/cold plumbing is rendered useless with an open cone filter such as used in a cold air intake system.
