Can't figure out what this hose is?

For some odd reason RockAuto calls it an Air Cleaner Intake Hose. I believe what it does is allow air to the throttle body if you quickly let off the gas pedal under boost. With a MAF system all air must be accounted for after it passes the MAF. If you quickly shut off the throttle under boost then that extra pressure has to go somewhere and it will backup into the turbo unless it has an outlet.

Yeah, I was having MAF related codes and hesitation as well as rough idle issues on my 2004, Took it to the mechanic, he pulled on the brake vacuum hose that's under the cover to the right of the engine, and it popped right out. He re-did the connection there and reset the codes and told me that air was being sucked into the engine through there, undermining the MAF sensor and throwing codes. He also told me to rev the engine and quickly found the s-shaped hose was cracked and upon removal, it broke into 2 pieces. He replaced it with a generic hose he found in his shop and though it's a little kinked, it solved my issues and I was up and running again.
