Opel Throttle Body 55562270 Equipped With 1.6L and 1.8L Gasoline Engines

Product Specification

1. Vehicle Compatibility (Core Applications)

    This throttle body is primarily compatible with Opel/Vauxhall models from the mid-2000s to early 2010s, especially those equipped with 1.6L and 1.8L gasoline engines (e.g., Z16XER, Z18XER).

Commonly Fitted Models Include:

• Opel Astra H (Model years 2004-2010)

• Opel Vectra C (Model years 2002-2008)

• Opel Zafira B (Model years 2005-2011)

• Corresponding Vauxhall models (UK market equivalents).

Important Note: Due to variations in vehicle specifications and model years, it is essential to verify the exact fit using your VIN (Vehicle Identification Number) in a reliable parts catalog or with your supplier before purchasing.

2. Product Features

• Genuine Part Number: 55562270. This is the original equipment manufacturer (OEM) part number from General Motors/Opel, meaning its design specifications are identical to the part installed when the vehicle was built.

• Electronic Throttle Body: This is a "drive-by-wire" type. It is controlled directly by the Engine Control Module (ECM) via an electric motor, eliminating the need for a traditional throttle cable.

• Integrated Sensors: Contains built-in position sensors to provide real-time feedback on the throttle plate's angle.

• Precision Engineering: Comprises high-precision components such as the throttle plate, motor, and gear mechanism to ensure accurate air flow control.

3. Advantages

• Perfect Fit and Performance: As an OEM-specification part, it ensures seamless integration with the engine management system, restoring the designed air intake efficiency and throttle response.

• Reliability: Manufactured to original equipment quality standards, offering greater assurance in material quality and durability for a longer service life.

• Resolves Common Issues: Direct replacement effectively fixes various problems caused by a faulty throttle body, such as illuminated check engine light, unstable idle, poor acceleration, and hard starting.

• Plug-and-Play Installation: Designed as a direct replacement. Installation typically requires a throttle adaptation/relearning procedure using a diagnostic scanner, but the physical installation process is straightforward.

4. Why Choose This Product?

• Ensures Vehicle Health: The throttle body is a core component of modern engine management. Choosing a reliable, correctly matched part is crucial for maintaining engine power, fuel economy, and emission compliance.

• Prevents Cascading Failures: A faulty throttle body can cause incorrect air-fuel ratios, potentially damaging other expensive components like the catalytic converter or oxygen sensors over time. Using a genuine part helps avoid secondary damage.

• Compatibility and Stability: Compared to aftermarket parts of unknown compatibility or inconsistent quality, using this OEM-numbered part maximizes post-installation system stability and minimizes fault codes or adaptation issues.

• Repair Efficiency: For professional technicians and owners who prioritize reliability, using an OEM-numbered part is the most efficient and lowest-risk repair solution, often resolving the issue in one go.
