Blow Off Valve Kit

The CTS Turbo Blow Off Valve Kit is engineered as a direct replacement for the failure-prone factory plastic unit found in the 2017-2019 Audi A4 2.0T. Constructed from durable T6061 billet aluminum with a stealthy black anodized finish, this atmospheric BOV kit is designed for longevity and reliable performance. Featuring a fully serviceable piston design, this blow-off valve ensures consistent operation and easy maintenance. It seamlessly integrates with the vehicle's factory electronics, meaning no check engine lights will appear, and installation is plug-and-play with no need for wiring extensions. The compact nature of the valve allows for a straightforward fit, even within the confined engine bays typical of modern VAG vehicles. This kit directly addresses common failure points of the stock component, such as torn diaphragms, cracked plastic, and electrical malfunctions. Its design prioritizes reliability, ease of installation, and provides a satisfying sound. The CTS Turbo Blow Off Valve Kit is warrantied against manufacturing defects for 12 months from the date of invoice.
