This used air filter box lid is designed for 1.4 VTI and 1.6 VTI petrol engines in a range of Peugeot and Citroën models. It secures the air filter element, maintains correct air flow to the intake tract and prevents unfiltered air from entering the engine. Replacement of the lid is a common repair when clips, seals or the plastic housing become damaged by age, heat or impact. The unit is referenced under part numbers V753482480 and 1420T5, which customers and workshops often use when searching for a matching spare.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Citroën C4 II, Peugeot 207, Peugeot 308
• Product Codes: V753482480, 1420T5
• Other Numbers: 1420R2 (Complete Air Filter Box)

Installation Recommendations

Follow these practical steps to fit the lid correctly. Intended for professional mechanics and competent DIYers:

• Work On A Cold Engine And Park The Vehicle On A Level Surface.
• Remove Fasteners: Undo clips, screws or clamps securing the lid. Keep all fasteners for re-use unless damaged.
• Inspect Seals And Filter: Check the air filter element, rubber gasket and retention clips. Replace the filter and any damaged seals at the same time.
• Fit The Lid Evenly: Position the lid so the seal sits flush in the housing groove. Reinstall fasteners without over-tightening to avoid cracking the plastic.
• Check Connections: Ensure intake hoses and resonators are correctly reattached and clamps are secure to prevent intake leaks.
• Final Check: Start The Engine And Listen For Whistles Or Sucking Noises That Indicate A Leak.

Why The Part Fails Most Often

• Plastic Fatigue And Cracking From Long-Term Heat Cycles In The Engine Bay.
