Intake Air Filter Connector For 1.8 16V And 2.0 16V Engines For Citroën And Peugeot Vehicles
This air intake filter connector is designed for 1.8 16V and 2.0 16V petrol engines used in various Citroën and Peugeot models. It links the air filter housing to the intake tract, ensuring a sealed airflow path to the mass airflow sensor (MAF) and the engine. A correctly fitting connector prevents unmetered air leaks, maintains engine performance and fuel economy, and helps avoid diagnostic faults related to air intake irregularities.
Application And Fitment
Suitable For Engines: 1.8 16V, 2.0 16V.
Typical Vehicle Fitment Examples:
- Citroën C4
- Citroën C4 Picasso
- Peugeot 307
Always verify the engine type and part number when selecting the correct connector. This part is commonly searched by its product codes, so using the OE numbers speeds up identification.
Technical Information
- Manufacturer: Stellantis

- Product Codes: 9649757480, 144073
- Additional Numbers: Not Listed
Function And Importance
The Connector Transmits Cleaned Air From The Air Filter To The Intake System. It Ensures Correct Metering At The MAF Sensor And Stable Intake Pressure. A Damaged Or Leaking Connector Can Cause Rough Idle, Loss Of Power, Elevated Fuel Consumption, And Fault Codes (Often Related To Airflow Or Lambda Regulation).
Replacement Procedure (Overview For Mechanics And Experienced DIYers)
- Work On A Cold Engine In A Well-Ventilated Area.
- Locate The Air Filter Housing And Trace The Outlet Hose To The Connector.
- Loosen Hose Clamps Or Quick-Release Clips Securing The Connector; Remove Any Attached Vacuum Lines Carefully.
- Inspect Mating Surfaces For Dirt, Oil, Or Broken Tabs; Clean The Area Before Fitting The New Connector.
- Fit The New Connector Ensuring Proper Orientation And Full Engagement On Both Ends; Use New Clamps If Possible And Tighten Securely Without Over-Torquing.
- Start The Engine And Check For Vacuum Leaks, Unusual Noises, And Proper Idle. Clear Any Related Fault Codes If Present.
Recommended Installation
Use High-Quality Hose Clamps And Replace Any Damaged Clips Or Rubber Seals During Installation. Inspect The MAF Sensor Boot And Air Filter Housing For Damage Or Oil Contamination. After Installation, Perform A Visual Leak Check And, If Available, A Smoke Test To Confirm Airtight Sealing.
Why This Part Fails Most Often
- Aging And Material Degradation: Rubber And Thermoplastic Components Harden, Crack Or Become Brittle Over Time, Especially When Exposed To Heat And Ozone.
- Heat And Engine Oils: Persistent Oil Mist From PCV Systems And High Under-Bonnet Temperatures Accelerate Deterioration.
- Poor Clamping Or Incorrect Installation: Loose Clamps Or Misaligned Fittings Lead To Unmetered Air Ingress.
- Mechanical Damage: Impact During Maintenance Or Contact With Moving Parts Can Tear The Connector.
Typical Signs That The Connector Needs Replacement: Visible Cracks, Loss Of Flexible Shape, Whistling Or Hissing From The Intake, Rough Idle, And Diagnostic Codes Related To Airflow Or Mixture.
Service Life And Maintenance
Service Life Varies With Use And Environment. In Normal Conditions The Connector Often Lasts Several Years, But It Is Common To Replace It During Routine Maintenance Or When Symptoms Appear. Inspect During Air Filter Changes And After Any Work Around The Intake Tract.
Suitable For
Automechanics And Competent DIY Enthusiasts Working On Citroën And Peugeot 1.8 16V / 2.0 16V Petrol Engines Who Need A Reliable Intake Connector Replacement Or Spare Part. Commonly Searched By OE Numbers 9649757480 And 144073.
