The Black Mamba turbo outlet kit is a direct replacement for the factory plastic pipe connecting the turbo to the intercooler on 2.0 TFSI EA888.3 engines found in the Audi S3 8V, Golf 7 GTI, Golf 7 R, Leon 3 Cupra, and more. Designed with a larger diameter and greater rigidity than the stock component, this high-flow turbo outlet pipe enhances power output—especially on tuned engines or those equipped with a high-capacity intercooler.Direct bolt-on installation Diameter: 63mm (2.5″) High-quality aluminum construction Multi-layer silicone couplers for durability Black textured finish Complete mounting kit included Note: Not compatible with DSG7 transmissions.
