Description
Air Intake Resonator Connector for Citroën and Peugeot 2.0i Engines
Description
This intake resonator connector is a direct-fit component designed for Citroën and Peugeot vehicles equipped with the 2.0i petrol engine. It links the air resonator (intake silencer) to the air intake tract, helping to smooth airflow, reduce intake noise and maintain consistent engine response. Ideal for professional workshops and DIY mechanics searching by OE numbers (9641733880, 143431), this part restores proper sealing and resonance characteristics after damage or wear.
Benefits
- Restores correct intake tract sealing to prevent unmetered air leaks that affect idle and performance.
- Reduces intake noise and resonance for a quieter engine bay.
- OE-compatible fit that simplifies replacement and reduces installation time.
- Valuable for mechanics and car owners who search by part numbers (9641733880 / 143431).
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C5; Peugeot 407 (vehicles with 2.0i engine)
- Product Codes: 9641733880, 143431
- Additional Numbers: OE Equivalent Numbers 9641733880 | Internal Tag 143431
Installation Recommendations
Replacement is straightforward for a trained technician or an experienced DIYer. Follow these practical steps:
- Work on a cool engine and ensure the intake system is depressurized.
- Remove the air intake hose clamps and detach the airbox or resonator as needed to access the connector.
- Inspect mating surfaces, gaskets and adjacent hoses for wear or oil contamination; clean before fitting the new connector.
- Replace or tighten hose clamps to the manufacturer’s recommended tension to avoid leaks; use quality clamps to prevent failure.
- After installation, check for intake leaks at idle and under load; listen for abnormal intake noise and verify stable idle.
Why This Part Fails
Common causes of failure include long-term heat and UV exposure that makes the plastic brittle, oil contamination from crankcase ventilation that weakens the material, mechanical damage during previous repairs, and clamp fatigue or improper installation allowing air leaks. Failure typically presents as hissing or fluctuating idle, reduced throttle response or a noisy intake.
Notes For Buyers
- Searchable by OE numbers 9641733880 and 143431 — include these in your search to find the correct replacement quickly.
- Inspect surrounding intake components (hoses, clamps, resonator box) when replacing this connector to prevent repeat failure.
- Designed for vehicles equipped with the 2.0i engine; verify engine type before ordering.
