Air intake for the throttle body hose

Hi, i have 2.5L z4 2003 auto,

The engine emission light came on and upon inspection there is a leak in the hose which i believe is called air intake for the throttle body.
The mechanic has quoted me $150 just for the part (a plastic hose!)...I was wondering whether anyone could tell me the part number so i can look for a cheaper one online perhaps.

Your help will be greatly appreciated.

Cheers

is this easy to change? maybe a DIY?
 
You need to remove the top of the airfilterbox, the maf, upper intake hose and then the lower intake hose (the part that is broken in this case).
The lower intake hose is fixed to the throttlebody (with a big hoseclamp), the idle control valve (smaller hoseclamp) and there's a vacuum line attached to it (you can just pull that off)
