Has anybody created brake ducts for S4?

Makeshift...
 

Some guys are taking ShopVac vacuum heads, hooking 'em up to ducting hose, and using tie-wraps to try and get air to the oh-so-warpable rotors.

The intercoolers are a major obstacle in ducting anything on this car. I am still waiting for a tuner to step up with a serious kit, like the TechArt kit for Porsches.

thanks, I'll take a look.

i made one for my a4 before the stoptechs. ducting was attached to the OE dust shields
 

3" hoses hanged under lower engine cover - it hanged low :(
what worked for me (@LRP) was a pair 3" blower fan taped to the steering knuckle blowing into the center of the rotor :) obviously there were no issues when turning. kinda annoying parts is the noise - remember KITT? :P

Istook did....
