CTS Turbo 8V.2/8Y RS3/8S TTRS 2.5T EVO 4" AIR INTAKE PIPE (FACTORY AIRBOX TO 4" INLET)
Run a factory airbox with the CTS Turbo 4" cast turbo inlet on your 2.5T EVO MK3 TTRS or 8V.2/8Y RS3 (facelift, 2018 and up). This 4" air intake pipe bridges the factory airbox to the CTS 4" turbo inlet, giving you a full 4" intake tract while keeping the OEM airbox in place.
The result is increased efficiency, power and torque across the entire powerband with a subtle bump in sound — ideal for anyone who can't run an open intake or simply prefers the stealth look.

- Great solution for those who can't run an open intake or prefer the stealth look
