Ready to start modifying your Audi B9 A4, S5, A5 or S5? Keeping your engine running cool when pushing more power is vital, and with CTS's direct-fit front mount intercooler, you are sure to stay cool while putting down some serious horsepower. 

The stock OEM intercoolers found in the 2018+ A4, S4, A5, or S5 just do not cut it when it comes to performance. If you are Stage 1 or higher, you will see a significant improvement over stock when swapping out the intercooler for an aftermarket upgrade.

At almost two times the size of the stock cooler, the CTS Turbo B9 intercooler not only has met extensive quality control and pressure testing, but its cast aluminum end tanks attach perfectly to the factory hose setup. This helps ensure a boost leak-free fit, getting you the increased horsepower and torque you are looking for.
