Description
Filter box, air filter housing for Citroën C3, Peugeot 1007 with 1.4 HDi 66 kW engine.
The air filter housing (filter box) designed for Citroën C3 and Peugeot 1007 with the 1.4 HDi 66 kW engine is an essential under-bonnet component that secures the air filter element and directs clean air to the engine. This replacement unit fits OE references 9647066980, 9647066880 and reference 1420L3, making it an ideal spare part for professional workshops and DIY mechanics seeking reliable airflow management and engine protection. Installing a correct, undamaged airbox helps maintain engine performance, fuel economy and prolongs the life of the air filter and intake sensors.
Suitable for routine maintenance or accident repairs, this airbox is a direct-fit part for vehicles listed and is commonly searched by its part numbers, so including the reference codes in your order ensures quick identification. Robust construction ensures secure mounting and proper sealing to prevent unfiltered air ingress. For mechanics, the unit speeds up replacement jobs and helps restore correct intake routing after wear, impact or broken mounting tabs.
Technical information
- Manufacturer: Citroën / Peugeot (Stellantis)
- Model: Citroën C3; Peugeot 1007
- Product Codes: 9647066980, 9647066880
- Other Numbers: 1420L3
Installation Recommendation
- Park the vehicle on a level surface, engage the handbrake and disconnect the battery if you will be handling electrical connectors (e.g., MAF sensor).
- Open the bonnet and locate the airbox assembly on the intake side. Remove the air intake hose clamps and any retaining clips or screws securing the top cover.
- Carefully disconnect the mass air flow (MAF) sensor and any breather hoses attached to the airbox—mark hoses if needed for correct reassembly.
- Remove the old housing, noting mounting points and rubber seals. Fit the replacement housing in the same orientation and secure all clips, screws and mounting fasteners.
- Reinstall the air filter element, reconnect hoses and the MAF sensor, then test for secure fitment and absence of air leaks before road testing the vehicle.
- Use a new air filter element when replacing the housing to guarantee proper sealing and filtration efficiency.
Most Common Failure Reasons
Airbox failures are usually caused by brittle plastic due to long-term heat cycling, broken mounting tabs from vibration or impact, and degraded sealing surfaces that allow unfiltered air to bypass the filter element. In some cases, previous improper removal or overtightening of fasteners can crack the housing. Accumulated dirt or oil can also affect seals and connections, compromising airflow hygiene and sensor readings.
Why Replace This Part
A damaged or leaky air filter housing can allow unfiltered air into the intake, risking premature engine wear and inaccurate mass air flow readings that affect drivability. Replacing the airbox restores proper intake routing, protects the engine, and ensures the air filter performs as intended. For professionals and home mechanics, replacing a faulty airbox is a cost-effective way to maintain engine health and avoid secondary damage to sensors and the intake system.
