Description
Air Intake Connector 1.4 VTi 70 kW 8FS 8FP For Peugeot And Citroën Vehicles.
Replace a worn or damaged air intake connector with this direct-fit component designed for 1.4 VTi 70 kW engines. Commonly referenced by part numbers 9656237580 and 1436L8, this intake connector is used on selected Peugeot and Citroën models and is often searched for by its product code. A correctly seated intake connector ensures stable airflow to the engine, preserves Mass Air Flow (MAF) sensor readings, and prevents vacuum leaks that can lead to rough idle, loss of power, or increased fuel consumption.
This part is intended for professional fitters and knowledgeable DIYers who service Peugeot/Citroën 1.4 VTi powertrains (engine codes 8FS and 8FP). It is a straightforward replacement that restores the air path integrity between the airbox and the throttle/intake tract. When replacing, inspect adjoining hoses, clamps, and sensor seals to ensure a leak-free installation.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model(s): Citroën C4 II, Peugeot 308 (1.4 VTi 70 kW)
- Product Codes: 9656237580, 1436L8
- Other Numbers: Engine Codes 8FS, 8FP; 1.4 VTi 70 kW
Function And Benefits
The air intake connector channels filtered air from the air filter housing toward the throttle body/intake tract. A correctly functioning connector maintains correct airflow measurements for the engine management system, helping to ensure smooth idling, accurate fueling and optimal performance. Replacing a damaged connector eliminates air leaks, reduces the risk of MAF sensor contamination, and restores engine responsiveness.
Installation Recommendations
- Perform the replacement with the engine cool and parked on level ground.
- Remove clamps or fasteners securing the old connector, detach any sensors or vacuum lines carefully, and note their routing.
- Compare the new part to the removed item to confirm fitment before installation.
- Install the connector ensuring proper seating at both ends; tighten clamps evenly to avoid crushing soft lips or deforming the component.
- Replace any brittle hoses, worn clamps or damaged seals encountered during the job to prevent future leaks.
- After installation, visually inspect for gaps and start the engine to check for smooth idle and absence of intake leaks. Clearing any stored fault codes may be required if engine management raised a fault prior to replacement.
Why This Part Commonly Fails
Air intake connectors are typically exposed to heat cycles, vibration and occasional chemical contamination (oil vapors), which over time can cause the material to become brittle, crack or develop torn sealing lips. Common causes of failure include age-related degradation, impact or improper handling during maintenance, broken mounting tabs, and perished seals that allow unmetered air into the intake system.
Search Tip: Many customers locate this part by entering the part numbers 9656237580 or 1436L8 in search engines or parts catalogs. Verify engine code (8FS / 8FP) and model fitment before ordering to ensure compatibility.
Additional Notes
This air intake connector is a direct replacement for the specified 1.4 VTi 70 kW applications listed above. For best results, inspect the entire intake tract and associated clamps and replace ancillary components as needed when performing the repair.
