I wanted to get some window vent visors for my 2016 Audi S6 in Mythos Black. Unfortunately, the car gets hotter than Hades sitting in even a moderate amount of sun. Without cracking the windows on a dark black Audi S6, your car will reach triple digits on the inside thermometer in a very short amount of time. But, then you have to worry about an easier theft target, and unexpected rain. This sent me on a hunt for Window Vent Visors, also called Window Splash Guards for a 2016 Audi S6 or 2016 Audi A6.
Note, the windows are the same on the 2015/2016 Audi S6/A6 so the parts are interchangeable.
I actually had a hard time at first finding the right Window ventvisors/window ventshades/windows wind deflectors, whatever you call it for an Audi S6, but eventually lucked out.
I found that the Weathertech 82703 Window Deflectors where what I was looking for that were compatible with a 2016 Audi S6. Oddly enough, Amazon lists the part as Weathertech 82703 Catalytic Converter, but as you can see in their picture, it is clearly a vent visor.
These Weathertech deflectors fit perfectly on a 2016 S6.
Notes on Weathertech 82703: No Tape, they use metal clips that slide under the weather stripping. The seem sturdy, are low profile, and don't change the appearance of the car much. Unfortunately, the back windows vents are sorta useless, because when you drop the window down a gap forms in the back rear side of the window as it opens (since they are inverted trapezoids). In other words you can only open the rear windows a hair without exposing them to some rain. These were simple to install, less than 10 minutes including unpackaging.
Here are pictures of the Weathertech 82703 Window Deflectors on a Mythos Black 2016 Audi S6:
