Description
Turbo hose, intake air resonator 1.4 HDI for Citroën and Peugeot vehicles. It is from Citroën C3 2003 8HY 66 kW.
This replacement turbo hose and intake resonator is designed to restore correct air flow and reduce intake noise on 1.4 HDi diesel engines. Built for direct fitment where the OEM part number 9647569980 / 144036 is used, the component helps maintain turbocharger response, prevents unmetered air leaks and supports stable idling — all crucial for fuel economy and engine performance. Suitable for professional workshops and DIY mechanics, the description contains the most relevant technical details and practical tips to ensure correct selection and installation.
Technical Information

Compatibility And Fitment Notes
Primarily taken from a Citroën C3 1.4 HDi (engine code 8HY). Often searched and referenced by OEM part number 9647569980 or secondary identifier 144036. Confirm vehicle uses the 1.4 HDi intake layout when selecting this hose/resonator; it is commonly found on small Stellantis diesel models sharing the same engine family, including some Peugeot 1007 variants.
Installation Recommendations
Installation is straightforward for a trained mechanic or experienced DIYer. Recommended steps:
- Work on a cool engine and disconnect the battery if required by surrounding components.
- Loosen clamps securing the hose to the turbo outlet, intercooler or intake manifold and carefully remove any mounting clips.
- Inspect mating surfaces and adjoining pipes for damage, oil residue or cracks; clean before fitting the new hose.
- Fit the new resonator/hose in place, align clamps and secure evenly to avoid pinching. Replace worn clamps if necessary.
- Start the engine and check for intake leaks and abnormal noise; perform a short test drive to ensure turbo response and idle stability are restored.
Why This Part Fails Most Often
Intake hoses and resonators are exposed to heat, vibration and occasional oil contamination from the turbo system. Common causes of failure include:
- Aging rubber or silicone that becomes brittle and cracks over time.
- Oil contamination from turbocharger seals or blow-by, which softens or degrades hose material.
- Loose or corroded clamps causing air leaks and movement that accelerates wear.
- Mechanical damage from engine bay maintenance or contact with hot components.
When a hose or resonator leaks, symptoms typically include rough idle, reduced turbo response, increased intake noise and sometimes a diagnostic fault related to air mass or boost control.
Practical Tips
- Always replace clamps if they show corrosion or spring weakness; a secure seal is essential for turbocharged engines.
- Inspect adjacent components (intercooler pipes, turbo outlet, intake manifold) for complementary damage when replacing the hose.
- Use part numbers (9647569980 / 144036) when searching to improve chances of direct-fit replacements and to speed up procurement.
This product description is intended to help you choose and fit the correct turbo hose and intake resonator for 1.4 HDi applications and to inform decisions during maintenance and repair.
