CTS Turbo B9 Audi A4, A5, AllRoad 1.8T/2.0T Charge Pipe Set (Turbo Outlet and Throttle Pipe)

At CTS Turbo we are proud to announce our new intercooler charge pipes for the B9 Audi A4, A5, AllRoad 1.8T/2.0T. The OEM charge piping uses a rubber hose as turbo outlet connection and plastic cold-side pipes with a flow-impeding "resonator". Factory piping is not optimized for performance; so we had to step in and make our charge pipe set of 2.5" aluminum mandrel-bent tube. Our parts replace soft turbo outlet hose and the small resonated plastic throttle body pipe. All of the components included in the CTS charge pipe set work flawlessly together to provide increased efficiency, horsepower and torque throughout the entire power-band. By removing the restricting resonator on the cold-side piping, you can enjoy a slight increase in turbo sound! Product Details:

• 2.5" Mandrel Bent Aluminium Pipe Set
