CTS TURBO 2.0T DIVERTER VALVE KIT (EA888.3)

The CTS Turbo 2.0T Diverter Valve Kit directly replaces the factory diverter valve on EA888.3 generation engines fitted to 2009-2020 Audi TT, A3 and S3 models. Factory plastic diverter valves are known to develop leaks and fail under elevated boost conditions, causing erratic boost control and hesitation. This precision-machined CTS Turbo solution uses higher-grade materials and revised internals to eliminate boost leaks whilst maintaining OEM-style recirculation. Designed for both stock and tuned applications, this kit provides consistent boost response and improved throttle behaviour across the rev range.
