Description
Air intake filter connector 1.8 and 2.0 16V for Citroën and Peugeot vehicles. It is from PEUGEOT 407 1.8 16V 6FY
This air intake filter connector is the replacement part used to link the air filter housing to the intake tract on 1.8 and 2.0 16V Citroën and Peugeot engines. It provides a sealed airflow path, preventing unmetered air from entering the intake and ensuring correct air mass measurement for stable idling and engine performance. Frequently searched by part numbers 9652780880 and 143176, this component is commonly found on Peugeot 407 1.8 16V (engine code 6FY) applications and compatible Citroën models.
Designed for professional garages and DIY mechanics, the connector is made to withstand typical under-bonnet conditions. Correct installation restores airtightness of the intake system, which helps avoid rough idle, air/fuel ratio errors and potential check-engine warnings related to airflow or intake leaks.

Installation Recommendations
- Work On A Cold Engine: Replace the connector only when the engine is cool to avoid burns and to ensure seals seat correctly.
- Inspect Mating Surfaces: Clean the airbox and throttle body connection points before fitting the new connector to ensure a tight seal.
- Use New Clamps: Replace retaining clamps where possible. Tighten clamps firmly but avoid over-tightening to prevent tearing the connector material.
- Check Orientation And Fitment: Ensure the connector is fitted in the correct direction and fully seated on both ends. Some variants have a shaped profile that must match the intake routing.
- Test After Installation: Start the engine and check for vacuum leaks, idle stability and absence of intake-related error codes. Inspect visually for movement after a short test drive.
Reason For Most Common Failures
- Aging And Heat Exposure: Over time the rubber/plastic material becomes brittle and develops cracks due to repeated heating and cooling cycles.
- Oil Contamination: Blow-by oil entering the intake can soften or degrade the connector material, accelerating failure.
- Mechanical Damage: Road debris, improper handling or over-tightening of clamps can cause tears or kinks.
- Vibration And Movement: Loose clamps or worn mounts allow excessive movement that stresses the connector and creates leaks.
There Is No Fixed Replacement Interval: Lifespan Depends On Operating Conditions. In workshop practice the part is usually replaced when visible cracks, deformation or intake leak symptoms appear. When replacing, consider inspecting the whole intake tract and clamps to avoid repeated failures.
