The engine in the A8 sounds fantastic, but the car is all to well isolated, so I wanted to install and K&N filter to increase sound.
I have done this many times before but this time I encountered something I have'nt seen before.
Inside the Airfilterbox there is a hole, going downwards. see the pic. What is this for? It was inside the filter so probably it needs a filter to?

Anyone with an Audi installed K&N?
