Anyone know what it is called or know the part number?
Tried to look for it online and even on the forums, can't figure it out.

 

Not sure of a seperate part number, but it is a part of the OEM air intake assembly. It is the pipe that connects from the air filter box to the throttle body. The flat extended piece is usually hidden under the factory engine cover.

 

17875-50170 - Pipe, Intake Air Connector.

It's a pricey mother****er.

 

Wow... and to think I just trashed my old one a few months ago.
