Adapter Plate With Electric Valve For Opel 2.0/2.2 DTI TiD
This Adapter Plate With Electric Valve is engineered for Opel/Vauxhall/Saab 2.0 and 2.2 DTI TiD engines, delivering a precise bypass solution that helps protect your intake from oil soot buildup and maintain consistent performance on the track. By replacing the original path with a dedicated blanking plate and an electric valve, hot exhaust gases are prevented from reaching the intake manifold. This reduces the risk of oil from the crankcase breather mixing with exhaust gases to form a sooty film that narrows the port diameter, which can otherwise sap engine power and raise fuel consumption. Built from durable aluminum and designed for performance applications, this adapter plate supports motorsport use and off-road scenarios where reliable airflow and consistent power matter most.
Note: The valve needs to be mapped out from the engine to avoid limp mode. An optional simulator can be used to suppress EML errors where required. For safety and reliability, use this kit in appropriate non-public-road environments and comply with local regulations.
Compatible with a wide range of Opel/Vauxhall/Saab models including the Astra III / F Classic (1999–2000) 2.0 DTi, Astra IV / G (1999–2005) 2.0 DTI and 2.2 DTI variants, Frontera II / B (1998 onward) 2.2 DTI, Signum (2003 onward) 2.0 DTI and 2.2 DTI, Vectra II / C (2002 onward) 2.0 DTI and 2.2 DTI, Zafira I / A (2000–2005) 2.0 DTI and 2.2 DTI, Saab 9-3 (1998 onward) 2.2 TiD and 9-5 (2002 onward) 2.2 TiD. The plate is designed specifically for engines in these families, with aluminum construction and a valve made from aluminum for robust performance in demanding conditions.
Benefits & Tips
- Maximize engine reliability on track days: By isolating the exhaust gas path, you reduce the chance of intake contamination and maintain steadier power output during high-load driving.
- Optimize installation and tuning: Plan to map out the valve from the engine and consider a compatible simulator to prevent EML/Limp Mode issues while you set up the system.
- Maintenance sanity-check: Keep the Viton o-ring clean and inspect the aluminum pipe and blanking plate for any signs of wear after intensive usage.
