At CTS Turbo we are proud to announce our new 4″ air intake pipe for the 2.5T EVO MK3 TTRS & 8V.2 RS3 (facelift) 2018 and up models to use with CTS 4″ cast turbo inlet pipe.

Do you want to run a factory airbox with CTS Turbo 4″ cast turbo inlet? This 4″ air inlet pipe will allow you to keep the factory airbox while providing a full 4″ intake tract.

The CTS air intake pipe works flawlessly with the OEM airbox to provide increased efficiency, power and torque throughout the entire powerband with a subtle increase in sound.
