CTS Turbo is proud to announce our Direct fit FMIC for the B9 platform. Now in our updated black finish!

The OEM B9 intercoolers deliver underwhelming performance, this platform benefits greatly from an intercooler upgrade. Vehicles at stock boost levels up through Stage 1-2 and Big Turbo applications will all see a large improvement over the factory equipped hardware.

This giant intercooler core is almost 2 times larger than stock and meets our extensive quality control and pressure testing (up to 50psi). Cast aluminum end tanks attach to factory hoses seamlessly to ensure a boost-leak free fit that results in increased horsepower and torque.
