Description
Air Inlet Connector For 1.4 VTi And 1.6 VTi Engines For Peugeot And Citroën Vehicles.
Direct-fit air inlet connector designed for 1.4 VTi and 1.6 VTi engines fitted to selected Peugeot and Citroën models. This part restores a sealed air intake path between the airbox and downstream intake components, helping maintain correct airflow measurement and engine performance. Frequently searched by OE numbers 9684577280 and 1436R0, it is a practical replacement for workshops and DIY mechanics who need a reliable, easy-to-fit intake connection.
Key Benefits
- Direct replacement for original air inlet geometry to ensure correct airflow and MAF sensor operation.
- Durable construction resistant to normal engine bay temperatures and vibration.
- Straightforward installation using factory mounting points and clamps.
- Commonly referenced by OE codes for fast lookup and ordering.

Function And Symptoms Of Failure
The air inlet connector links the air filter housing to the intake tract and ensures a sealed, turbulence-minimised airflow to the mass air flow (MAF) sensor and the engine. When the connector develops cracks, splits or loose joints it can cause vacuum leaks and unmetered air, which often leads to rough idle, hesitation on acceleration, incorrect air/fuel mixture and possibly an illuminated engine warning lamp.
Why The Part Typically Fails
- Aging And Heat Exposure: Rubber and plastic materials become brittle over time and can crack under repeated heating and cooling cycles.
- Oil Contamination: PCV/oil vapour accumulation can degrade the material and encourage softening or swelling.
- Mechanical Damage: Improper installation, impact, or overtightened clamps can cause tears or deformation.
- Poor Seal Or Loose Clamps: Loose or corroded clamps allow movement and air leakage at the joints.
Replacement Procedure
- Allow The Engine To Cool And Ensure The Ignition Is Off.
- Loosen And Remove The Hose Clamps Securing The Old Connector To The Airbox And The Intake Pipe.
- Carefully Detach Any Sensors Or Mounting Clips Attached To The Connector (Observe Sensor Wiring).
- Remove The Old Connector And Inspect The Mating Surfaces, MAF Sensor And Airbox For Contamination Or Damage.
- Fit The New Connector In Place Making Sure It Is Properly Seated On Both Ends; Reinstall Clamps And Tighten Securely But Without Over-Torquing.
- Reconnect Any Sensors Or Clips And Start The Engine To Check For Air Leaks, Smooth Idle, And Proper Throttle Response.
Installation Recommendations
- Use Original-Style Clamps Or Quality Hose Clamps To Ensure An Airtight Seal.
- Inspect The MAF Sensor And Clean If Needed Before Reassembly To Avoid False Readings.
- Replace Any Damaged Clips Or Mounts At The Same Time To Prevent Future Movement.
- After Installation, Check For Vacuum Leaks By Listening Around The Joint At Idle Or By A Smoke Test Per Workshop Practice.
- Keep Work Area Clean To Prevent Debris Entering The Intake During Replacement.
Who Should Fit This Part
Suitable For Professional Technicians And Competent DIY Mechanics. The part is designed for straightforward replacement without special tooling, but care should be taken when handling intake sensors and when reseating clamps to ensure a reliable, airtight installation.
