Description
Intake resonator connection for CITROËN and PEUGEOT vehicles with 2.0i engines
This used intake resonator connection is a direct-fit part for Citroën and Peugeot 2.0i petrol engines. Commonly searched by product numbers 9626612880 and 14265E, it links the air resonator to the intake system, helps dampen induction noise and ensures correct airflow to the throttle body. Ideal for professional mechanics and DIY enthusiasts who need a reliable replacement part that restores airtightness and engine response in the low and mid rpm range.
Technical Information
Manufacturer: Stellantis / Citroën / Peugeot
Model: Citroën C5, Peugeot 407 (2.0i)
Product Codes: 9626612880, 14265E
Other Numbers: NFP
Function
The connector joins the intake resonator to the air intake tract. It reduces induction noise, cushions airflow pulsations and helps maintain steady pressure and flow to the throttle body. A sealed, correctly fitted connector prevents unmetered air entering the intake, which can otherwise cause rough idling or drivability issues.
Fitment And Replacement
Fitment is typically straightforward for technicians familiar with PSA engine bays. Access the resonator and intake snorkel by removing the engine cover and any obstructing trim. Loosen hose clamps or remove retaining clips, slide off the old connector and inspect adjoining ducts for damage. Fit the new connector, ensuring a snug fit on both mating parts and re-tighten clamps to secure an airtight seal. After installation, start the engine and check for vacuum leaks or abnormal induction noise.
Installation Recommendations
– Work on a cool engine and keep the intake area clean to avoid debris entering the system.
– Use appropriate stainless or OEM-style hose clamps and avoid overtightening which can deform the connector.
– Inspect adjacent components (airbox seals, MAF sensor boot, resonator housing) for wear when replacing the connector.
– After assembly, verify idle stability and perform a visual leak test (soapy water or smoke) if available.
Why This Part Fails Most Often
Failures are usually caused by age-related material fatigue, heat cycles, and mechanical vibration. Exposure to engine bay heat, oil contamination from crankcase ventilation systems, or impact from road debris can lead to cracks, hardening or deformation of the connector. Once the seal is compromised, symptoms include increased induction noise, erratic idle, loss of low-end torque or error codes related to airflow inconsistencies.
How Often It Fails
There is no fixed replacement interval; the connector often lasts many years but should be inspected during routine service or when symptoms appear. Vehicles exposed to frequent short trips, high underbonnet temperatures or oil blow-by may require earlier replacement.
Note On Search And Identification
This part is frequently searched by its product numbers (9626612880, 14265E). Use these reference numbers when checking fitment for Citroën C5 and Peugeot 407 2.0i applications to speed up identification.
