Heat kills performance. Today we will upgrade my 2018 Audi S4 (B9 3.0L V6 TFSI) with a shiny new Front Mount Intercooler from ECS Tuning. Intercoolers are essentially heat exchangers for compressed air generated by a turbo or supercharger. Our S4s are turbocharged from the factory and make lots of heat. Combined with tunes, hybrid turbo upgrades and full frame builds the amount of heat created can be astounding. The factory FMIC was just too small to deal with these heat levels, especially in hot climates.

When doing back to back Dragy 1/4 mile runs you can see the performance decline as the car heats up. After installing the intercooler it was clear the performance was much more stable and allows you to focus on better launches, traction and other factors instead. The install overall is fairly straightforward, but I would suggest planning on it being an over the weekend job.
