Description
Air connection at the turbocharger for 2.0 HDI RHR engines of Citroën and Peugeot vehicles.
This turbo inlet pipe is a direct-fit replacement designed for the 2.0 HDI RHR diesel engines. It restores correct air routing to the turbocharger, helps maintain boost pressure and engine response, and is commonly searched by its part numbers 9651164580 and 0382FH. A reliable intake connection is essential for steady turbo operation and fuel-efficient combustion — ideal for professional workshops and DIY mechanics who maintain Citroën and Peugeot models.
Key Benefits
– Direct fit for specified 2.0 HDI RHR applications; simplifies replacement and reduces downtime.
– Restores proper turbocharger airflow, improving throttle response and preventing boost leaks.
– Manufactured to OE-style dimensions to ensure correct sealing and clamp alignment.
Compatibility
Designed for 2.0 HDI RHR diesel engines in a range of Citroën and Peugeot models, including but not limited to:
- Citroën C5 (including X7 variants)
- Citroën C8
- Peugeot 307
- Peugeot 407
- Peugeot 807
Installation Overview
Replacing the turbo inlet pipe is a straightforward job for a trained technician or an experienced DIYer with basic workshop tools. Typical steps:
- Allow Engine To Cool. Work only on a cold engine to avoid burns and material damage.
- Gain Access. Remove the necessary engine covers or air intake components to access the turbo inlet connection.
- Loosen Clamps. Loosen hose clamps or fasteners securing the pipe to the turbocharger and intercooler/intake ducting.
- Inspect Adjacent Components. Check clamps, seals, intercooler hoses and turbocharger outlet for oil contamination or damage.
- Fit New Pipe. Install the new pipe, align correctly and secure clamps to the manufacturer’s recommended tightness to avoid leaks.
- System Check. Start the engine and inspect for hissing, boost leaks or loose connections. Road test to confirm restored performance.

Installation Recommendations
– Replace clamps and sealing rings where applicable to ensure a reliable, pressure-tight joint.
– Inspect turbocharger shaft seals and intercooler for oil contamination; oil ingress can degrade rubber and silicone hoses.
– Torque clamps evenly and avoid overtightening metal-to-metal joints to prevent distortion of the pipe.
– After installation, perform a boost leak check and a short road test under load to verify proper operation.
Most Common Failure Causes
– Ageing And Material Degradation: Heat cycles and engine bay temperatures cause rubber and silicone components to harden, crack or become brittle over time.
– Oil Contamination: Turbocharger oil leaks or excessive crankcase vapour can soften hose material and lead to swelling or splitting.
– Corroded Or Loose Clamps: Corrosion or poorly secured clamps allow the pipe to slip under boost, causing intermittent boost loss and performance issues.
– Mechanical Damage: Contact with adjacent components during previous repairs or rough handling can cut or deform the pipe.
Symptoms of a failing turbo inlet pipe include hissing or whistling under boost, reduced acceleration, turbo lag, and occasional engine fault codes related to boost pressure. Replacing the defective pipe typically restores normal boost behavior and engine response.
