Part description
This air intake is intended for Citroën and Peugeot cars with 1.6 HDI engines. It is a used original part that is suitable as a replacement for a damaged, leaking or clogged original intake. When choosing, searching by production numbers is also important for many customers, so we also include the corresponding part codes in the description.
The part is marked as fully sealing, however, it should be taken into account that soot contamination may occur with this type of part, and therefore it is advisable to carry out a thorough inspection and cleaning before assembly.

Installation recommendations
Generally/typically for this type of part, the exact replacement procedure may vary depending on the specific car design and engine compartment layout. Below is a safe and practical general procedure for replacing a part in the air intake category.
1) Before assembly
- Check that the new air intake matches the old piece by shape, connection points and product numbers.
- Check the condition of the sealing surfaces, mounting and connecting parts.
- Because the documents indicate the possibility of soot contamination, carefully clean the internal passages before assembly.
- Remove residual dirt, oil deposits and old pollution that could restrict airflow.
- Compare the condition of any seals and consider replacing them if they show wear.
2) Necessary tools and materials
- A common set of hand tools
- Screwdrivers and socket wrenches of appropriate sizes
- Cleaning agent suitable for removing soot and grease
- Clean rags without loose fibers
- Work gloves
- Or new sealing elements, if the original ones are damaged during disassembly
3) Step-by-step assembly procedure
- Shut off the engine and let it cool down.
- Ensure sufficient access to the original part by removing obstructing covers or attachments as needed.
- Carefully disconnect the connecting hoses, couplings and fasteners of the old air intake.
- Disassemble the original part so as not to damage the surrounding plastic or metal parts.
- Check the contact surfaces and carefully clean them of soot, dust and dirt residues.
- Visually check the prepared used part again, especially the tightness, cleanliness and integrity of the attachment.
- Place the air intake in place in the same position as the original part.
- Install the fasteners evenly and without force to avoid stressing or cracking the part.
- Reconnect all hoses and fittings so that they are properly seated and do not create a false leak.
- Check that nothing is left loose, crooked, or undertightened.
-
4) Post-assembly checks and test drive/function verification
- After assembly, perform a visual check of the correct seating of the entire part.
- Start the engine and observe for signs of leaks or abnormal behavior.
- Check that all attached parts are firmly in place.
- After a short test drive, re-verify that the part has not come loose and that there is no leakage or air intake outside the designated route.
5) The most common assembly mistakes + how to avoid them
- Assembly without cleaning the part – always remove soot and deposits before installation.
- Overlooking damaged sealing surfaces – check and clean everything carefully before assembly.
- Incorrect seating of hoses and connections – after assembly, manually verify that all connections are properly seated.
- Too rough handling – especially with plastic parts, proceed carefully to avoid cracks.
- Ignoring the follow-up check after assembly – perform a repeat check after the first start and after a short drive.
Reasons why the part is damaged
- Clogging with soot, which restricts the passage of air and impairs the function of the part.
- Long-term exposure to dirt and greasy deposits in the intake system.
- Leaks in subsequent parts that can cause higher stress on the part.
- Mechanical damage during unprofessional disassembly or assembly.
- Age of material and normal operational wear and tear.
