Description

The CTS Turbo 4″ Straight Coupler is a crucial component for performance intake systems on select Audi vehicles. This coupler measures 4 inches in inside diameter and is 6 inches in length, constructed from durable 4-ply silicone for robust performance. Specifically designed to facilitate the installation of CTS Turbo 4″ intakes and 4″ turbo inlet pipes, this coupler is a requirement for the RS3 8V and MK3 TTRS models when utilizing the CTS turbo inlet pipe. The product includes one clamp for secure attachment to the turbo inlet pipe. Fitment is directly tied to specific CTS Turbo part numbers, including the CTS-IT-255R (4″ DAZA 2.5T intake) and the CTS-HW-360 (4″ DAZA 2.5T turbo inlet pipe). Ensure compatibility with these part numbers for proper integration.
