2.5-Inch Mandrel Bent Throttle Pipe

The CTS Turbo Throttle Pipe is engineered to replace the stock charge piping on VW Gen 3 TSI (EA888.3) engines, addressing inefficiencies and blockages for enhanced performance. By increasing the internal diameter to a full 2.5 inches, this pipe allows for greater airflow, leading to improved efficiency, horsepower, and torque across the entire power band. The construction features durable, mandrel-bent aluminum piping finished with a protective black powder coating. Critical components like the MAP flange are CNC machined for precision, while a 4-ply silicon connector and stainless steel clamps ensure a secure and reliable seal. A key feature of this throttle pipe is the integrated bung, which simplifies the installation of water-methanol injection kits from brands like Snow Performance or AEM. This addition provides further tuning and performance potential for enthusiasts. The kit includes all necessary components for a straightforward installation, though users have noted the importance of ensuring clamps are tightened securely to prevent issues like EPC lights. The overall result is a more aggressive, race-inspired engine sound. This throttle pipe is specifically designed for the Gen3 (EA888.3) 1.8TSI and 2.0TSI engines found in Jetta, Jetta GLI, Passat, and the new Beetle. It is explicitly stated that this part does NOT fit the MK7 GTI, Golf, or Golf R models. Fitment includes VW Mk6 (2011-2014), Mk6.5 (2015-2018), and Passat B7 (2012-2019) models with the relevant TSI Gen 3 engines.
