Diverter Valve Turbo Blow Off for Audi S3 and VW Golf R 2.0 TFSI

Upgrade your turbocharged Audi S3 or VW Golf R with this Diverter Valve Turbo Blow Off Kit. Crafted from durable aluminium and finished in a sleek silver, model 1138, it’s designed specifically for ETI VAG group engines with a transversal layout. This kit relocates the diverter valve away from the hottest zone near the turbo, reducing heat-induced wear and delivering steadier boost response.

How it solves common problems: OEM diverter valves often suffer heat exposure, which can lead to leaks and a gradual drop in throttle response. By moving the valve to a cooler region, you minimize heat-related damage and ensure fresh air recirculates through the intake. Colder, denser air improves cylinder filling, helping you achieve more efficient combustion and stronger, more reliable performance across RPMs. The design also directs boost pressure just before the throttle body, while keeping air cooled by the intercooler path for optimal charge density.

Compatibility for enthusiasts who demand a precise fit: this kit is suitable for Audi S3 and VW Golf R 2.0 TFSI transversal ETI VAG group engines. For installation you will need an intake pipe including the diverter connection, and in vehicles without a noise amplifier, additional components may be required.
