Description

The CTS Turbo 4″ Straight Coupler is a crucial component for upgrading the intake and inlet piping on select Audi models. This coupler measures 4 inches in inside diameter and is 6 inches long, with a robust 4-ply silicone construction to withstand demanding engine conditions. This specific coupler is required when installing the CTS Turbo 4″ intake (part number CTS-IT-255R) and the CTS Turbo 4″ turbo inlet pipe (part number CTS-HW-360) on the 8V RS3 or MK3 TTRS with the 2.5T engine. The coupler facilitates the connection between these components, ensuring a secure and efficient flow of air into the turbocharger. Included with the coupler is one clamp necessary for attaching it to the turbo inlet pipe. The 4-ply silicone construction provides durability and resistance to heat and pressure, making it a reliable upgrade for performance enthusiasts.
