Description
Turbo hose, intake air resonator 1.6 HDI for Citroën and Peugeot vehicles
This turbo hose with integrated intake resonator is designed for 1.6 HDI engines used in Citroën and Peugeot models. It reduces intake noise, evens out pressure fluctuations in the intake tract and ensures stable airflow between the turbocharger and the intake system. The part is commonly searched by OEM numbers, so see the technical section below for exact codes. Suitable for professional workshops and DIY mechanics who need a direct-fit replacement to restore boost response, reduce unwanted intake drone and eliminate intake leaks that can cause poor running or turbo lag.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C5, Peugeot 407 (1.6 HDI variants)
- Product Codes: 9657083380, 144057
- Additional Numbers: Not Specified
Fitment And Application Notes
Intended for 1.6 HDI diesel variants of Citroën C5 and Peugeot 407. The hose functions as part of the turbo intake system and is fitted where the resonator chamber reduces pressure pulses and intake noise. Always verify that the shape and hose connections match your vehicle’s existing parts list and routing before installation.
Installation Recommendations
- Prepare basic tools: screwdrivers (flat and Phillips), pliers, and a set of hose clamps. In a workshop setting, use appropriate clamp pliers or torque tools if required by clamp type.
- Allow the engine to cool. Relieve any residual boost pressure by cranking the engine with the intake hose disconnected only if recommended by the vehicle service manual.
- Loosen and remove clamps securing the old hose. Pay attention to vacuum or sensor connections—label or photograph routing if needed for correct reassembly.
- Clean mating surfaces and inspect nearby components (intercooler pipes, clamps, sensors) for damage or oil contamination before fitting the new hose.
- Fit the new resonator hose in the correct orientation. Secure clamps evenly and firmly—avoid over-tightening on plastic connections; use metal reinforcement or replacement clamps if required.
- Start the engine and check for air leaks, loose clamps or abnormal noises. Re-check after a short test drive.
Common Failure Causes
- Aging and Material Fatigue: Repeated heat cycles and vibration cause rubber or silicone to harden, crack or split at stress points.
- Oil Contamination: Turbocharger oil leaks or excessive crankcase vapors can degrade internal hose walls and lead to collapse or internal swelling.
- Clamps And Connections: Loose or corroded clamps allow boost leaks; improper clamp type can damage the hose or fail to seal.
- Mechanical Damage: Road debris, contact with hot components, or improper previous repairs can puncture or abrade the hose.
- Symptoms Of Failure: Reduced boost pressure, loss of engine power, increased turbo lag, whistling or hissing noises from the intake, and check engine lights related to MAF/boost pressure readings.
Searching by product code (9657083380, 144057) is a reliable way to find the correct replacement for the specified 1.6 HDI applications. Use original-style clamps and follow the installation steps above to ensure long service life and trouble-free operation.
