Aluminum Blow Off Valve Adaptor for Audi TT 2.0T VAG FSiT TFSi Turbo Turbocharger
Upgrade your turbocharged Audi and VAG family with a high-performance Blow Off Valve Adaptor crafted from polished aluminum. Specifically designed to replace the standard plastic diverter valve, this BOV adaptor delivers reliable boost control, reduces compressor surge, and enhances throttle response across a wide range of 1.4–2.0 TSI/FSTi turbo engines. Built to endure everyday driving and modified setups, it helps you achieve consistent boost pressure while adding a crisp, audible boost release that enthusiasts love.
Main Description
Designed for the demanding environment of modern turbo systems, this Audi TT 2.0T BOV adaptor provides a robust aluminum body, dual piston operation, and a secure 1" inlet diameter. It’s compatible with a broad array of VAG group models including Audi, SEAT, Skoda, and Volkswagen vehicles equipped with FSI/TFSi/TSi turbocharging. By replacing the brittle plastic valve, you gain improved boost stability, quicker response, and a more predictable, tunable intake system—crucial for both street driving and performance-oriented setups.
Key features that stand out include a durable polished aluminum body, a dual piston design for precise actuation, and a practical 25 PSI operational ceiling that suits many popular turbo configurations. The adaptor is ready for DIY enthusiasts but can also be installed by professionals for optimal results. Note: this part does not fit the twin charged 1.4 engine (Turbo and Supercharger).
Compatibility spans a wide range of models—from Audi A3 and TT variants to SEAT, Skoda, and VW platforms—ensuring you can upgrade across multiple vehicles without changing the core component. Each unit is tested before shipping to ensure reliability and performance, helping you avoid common OEM valve failures and the associated boost fluctuations.
