Show original supplier description
The CTS Turbo Diverter Valve (DV) Kit for the B9 Audi A4, A5, and Q5 models with the 2.0T engine is designed to replace the original plastic diverter valve. This factory unit is known to be prone to failure due to torn diaphragms, cracked plastic, or electrical issues, leading to performance problems. This recirculating DV kit integrates seamlessly with the vehicle's existing electronics. Installation is straightforward, allowing for a direct replacement of the OEM component. By upgrading to the CTS Turbo Diverter Valve Kit, you can ensure more reliable boost control and prevent potential issues associated with a failing factory diverter valve. The robust construction aims to provide a durable solution for performance-oriented Audi drivers.
