Our Audi B9 S4 gets a massive Unitronic Intercooler! The B9 S4 has a very small intercooler from Audi and upgrading the Intercooler is extremely beneficial when trying to get the most out of the B9 S4's 3.0T. Special thanks to Axel Automotive for having us and installing the Unitronic Intercooler! As we wrap up all the hardware mods for the Audi B9 S4 we will finally get the Stage 1+ tune in the next Vlog.
