CTS Turbo 8V.2/8Y RS3/8S TTRS 2.5T EVO 4" AIR INTAKE PIPE (FACTORY AIRBOX TO 4" INLET)

The CTS Turbo EVO 4-inch air intake pipe replaces the restrictive factory connection between your Audi RS3 or TTRS airbox and turbo inlet. Engineered specifically for 2018-2023 8V.2, 8Y RS3 and 8S TTRS 2.5-litre turbocharged models, this mandrel-bent aluminium pipe increases internal diameter to 4 inches, eliminating a major airflow bottleneck. The enlarged bore supports higher boost levels and complements aftermarket intake systems or upgraded turbos. Precision CNC flanges ensure direct fitment to factory mounting points, while smooth internal transitions reduce turbulence for measurable efficiency gains across the rev range.
