B8.5 Audi S4 MercRacing Heat Exchanger Install DIY | B8 & B8.5 S4, S5, SQ5

I got to install my old MercRacing heat exchanger on my friends B8.5 S4, so I decided to make a video for all you B8 guys since there are some small differences compared to a C7. Keep in mind this is a V1 MercRacing HX, but the installation will be just the same for any of the new versions from them.
