Description
Air Intake Connector For 1.4 VTi And 1.6 VTi Engines For Peugeot And Citroën Vehicles.
Replace cracked or leaking intake hoses quickly to restore engine response and eliminate vacuum leaks. This air intake connector (common reference numbers 9684577280 / 1436R0) links the air filter housing to the throttle body/air intake tract on 1.4 VTi and 1.6 VTi petrol engines used across several Peugeot and Citroën models. It Is Molded In Durable Plastic To Provide A Sealed Path For Metered Air; A Faulty Connector Causes Unmetered Air Ingress, Triggering Rough Idle, Hesitation, Or Fault Codes Related To Mass Airflow And Mixture.
Key Benefits
Direct Fit For Common PSA Engine Layouts — Fast Replacement To Remove Intake Leaks, Restore Idle Stability, And Improve Throttle Response. Ideal For Professional Workshops And DIY Enthusiasts Who Search By Part Number (9684577280, 1436R0).

Installation Recommendations
- Inspect The Surrounding Intake Components And Mass Airflow Sensor For Contamination Or Damage Before Installing The New Connector.
- Remove The Airbox Cover And Loosen Hose Clamps Securing The Old Connector; If The MAF Sensor Is Attached To The Duct, Disconnect Its Electrical Connector Carefully And Protect It From Contamination.
- Slide Off The Old Connector, Clean Mating Surfaces, And Fit The New Connector Ensuring It Seats Fully On Both Ends.
- Use New Hose Clamps Or Reuse Quality Clamps; Tighten Securely Without Over-Torquing To Avoid Distorting The Plastic.
- After Installation, Start The Engine And Check For Vacuum Leaks, Abnormal Noises, Or Check Engine Lights; If Needed, Clear Fault Codes And Verify Normal Idle And Throttle Response.
Why This Part Fails Most Often
Plastic Intake Connectors Are Exposed To Heat Cycles, Under-Hood Vibration, Engine Bay Contaminants (Oil Vapors), And Mechanical Stress From Hose Clamps. Over Time They Become Brittle, Develop Cracks, Or Lose Seal Integrity At The Clamp Zones. Improperly Installed Or Over-Tightened Clamps Accelerate Wear. When The Connector Leaks, Air Enters Unmetered, Causing Rough Idle, Loss Of Power, Hesitation, And Fault Codes Related To Airflow Or Fuel Trimming.
Practical Tips
- Inspect The Connector During Every Air Filter Service Or When Diagnosing Rough Idle/MAF-Related Codes.
- Replace Clamps When They Show Corrosion Or If Their Teeth Slip; Use Worm Gear Clamps Or OEM-Specified Clips For Reliable Sealing.
- Keep The MAF Sensor Clean And Protected During Replacement To Avoid False Readings.
