Description
Filterbox for Citroën C4 Picasso, C5 X7, C8 and Peugeot 308, 3008, RCZ, DS5 with 2.0 HDi engine
This genuine-style airbox is designed for PSA Group 2.0 HDi diesel engines and provides a secure housing for the air filter element, protecting the engine from dust, debris and moisture while ensuring stable airflow to the turbocharger and mass air flow sensor. Suitable for professional workshops and DIY mechanics, the unit is frequently referenced by its OEM codes and fits a range of Citroën and Peugeot models, making it a common replacement part during collision repairs or when the original housing is damaged.
Key Benefits
Robust construction and precise fitment minimize intake leaks and allow reliable mounting of the MAF sensor and intake ducts. Clear OEM product codes simplify ordering and help you locate the correct part quickly. Replacing a damaged airbox restores correct airflow, helps maintain fuel economy and reduces the risk of unmetered air affecting engine management.

Installation Recommendations
- Work With The Engine Cold And Ignition Off. Remove intake ducts and loosen hose clamps securing the airbox.
- Disconnect Electrical Connectors Carefully. If the MAF sensor is attached to the airbox, unplug the connector gently and unbolt the sensor without deforming it.
- Unclip Or Unscrew The Airbox Halves. Remove the old housing and transfer any required mounts, seals or fittings to the new unit if needed.
- Fit New Airbox And Seals. Ensure All Sealing Surfaces Are Clean, Replace Damaged Clips Or Gaskets, And Tighten Clamps Securely To Avoid Intake Leaks.
- Reconnect Sensors And Ducts. Start The Engine And Check For Air Leaks, Unusual Noises, Or Fault Codes Related To The MAF Sensor.
- Recommended Tools: Screwdrivers, Torx/Socket Set, Pliers For Clips, Clean Cloth For Sealing Surfaces.
Service Interval And Practical Advice
The Airbox Itself Is Not A Regular Wear Item; Replace It When Cracked, Broken Or After Accident Damage. Inspect The Airbox Each Time You Change The Air Filter (Typical Filter Change Interval 20,000–40,000 Km Depending On Driving Conditions). Replace Broken Clips And Seals To Prevent Unmetered Air Ingress.
Why The Part Most Often Fails
- Physical Damage From Road Debris Or Minor Collisions Causing Cracks Or Broken Mounts.
- Degraded Or Missing Clips And Seals Leading To Air Leaks And Poor Sensor Readings.
- Water Ingress Due To Poorly Sealed Or Incorrectly Mounted Intake Ducts.
- Warping Or Fatigue From Heat Cycling, Especially On Older Vehicles.
