Audi S5 V8 intake box

Hi I was adding a K&N filter to my S5 and notice the hose on the corner. "I think goes to the air pump" The foam was brittle and fell off. What is the part number to replace it?

Thanks

Lol, i just dropped K&N in mine Wednesday after oil change. It was my first oil change, but i swear i notice considerable power gain with motul lof & K&N combo. Sorry, for going off topic.

I could t find that part number either and needed to replace my worn out one.

I went to a Sears and bought a tiny foam air filter for a lawn trimmer. I trimmed it to size. Simple and effective. Sadly, no extra HP.

Thats the secondary air pump filter port.
