Adapter Plate For Opel Vauxhall Saab 2.0 And 2.2 DTI TiD Engines With Electric Wahler Valve

Designed for Opel, Vauxhall and Saab 2.0 and 2.2 DTI TiD engines, this adapter plate pairs with an electric Wahler valve to provide a precise, race-ready modification. The aluminum plate blanks the exhaust gas recirculation (EGR) path, helping to prevent the hot exhaust gases from reaching the intake manifold. Over time, oil from the crankcase breather can mix with exhaust gases and form a sooty film that coats the intake and valve, narrowing the port diameter and reducing power and increasing fuel consumption. This adapter plate is engineered to address that issue, delivering more consistent airflow and potential power gains in track or controlled environments.

The system requires engine mapping to avoid limp mode, and a simulator can be used to prevent EML/check engine light errors. This kit is intended for use outside public roads and in motorsport settings. The valve is made from aluminum and the overall construction uses durable aluminum for reliable performance under demanding conditions. The package includes the essential components to install and configure the setup on compatible Opel/Vauxhall/Saab engines.

Compatibility highlights include Astra III / F Classic (1999–2000) 2.0 DTi, Astra IV / G (1999–2005) 2.0 DTI 16V and 2.2 DTI, Frontera II / B (1998–) 2.2 DTI, Signum (2003–) 2.0 DTI and 2.2 DTI, Vectra II / C (2002–) 2.0 DTI 16V and 2.2 DTI 16V, Zafira I / A (2000–2005) 2.0 DTI 16V and 2.2 DTI 16V, Saab 9-3 (1998–) 2.2 TiD, and Saab 9-5 (2002–) 2.2 TiD. This specificity helps ensure you’re choosing the right kit for your engine family and model year.

Benefits & Tips

• Stay ahead in motorsport setups by minimizing intake soot buildup, which can otherwise throttle airflow and reduce performance.
• Map the injector/valve configuration to avoid limp mode; if you’re running a test setup, a simulator can help suppress EML codes during development.
• Choose this aluminum adapter plate for durability and consistent heat resistance in high-load environments where turbocharged diesels operate at peak efficiency.
