air box?

hi just curious about my air box on my 1.8 turbo Toledo 2003.

I recently killed my 1.8 t cupra so bought something similar but different if you get me.

went to fit a new air filter and the Toledo has a alien part (to me anyway)

the air filter has a hose coming out the bottom left of it that runs down under the front of the block to something I cant see.

any idea what this is???

I haven't done anything to the car just left it until I know what I'm taking apart??

goes to the secondary air pump. you can just stick a small filter on it if you want, and tuck it out of the way.

that or you can do a whole SAI delete.
