Description
Air intake filter connection 1.8 16V and 2.0 16V for Citroën and Peugeot cars
Part description
This air connection / intake air filter connection is a used original car part intended for Citroën and Peugeot cars. It is a part of the intake system that helps to correctly guide the intake air between the connected parts of the intake. Good condition of the part, tightness of joints and undamaged bearing surfaces are important for the proper functioning of the engine.
The part is also searched by production number, so when choosing it is worthwhile to compare the markings 9649757480 and 144073 with the original piece. It is particularly suitable for mechanics and home repairs, where the emphasis is on quick replacement of worn or cracked intake parts without unnecessary compromises.

Installation recommendations
Generally/typically for this type of part, the exact replacement procedure may vary depending on the specific design of the car and the arrangement of the engine compartment. For the suction connection, it is always important to carefully compare the shape, diameter of the connection and the condition of the sealing surfaces.
1) Before assembly
- Check the used part for cracks, deformations, broken edges or damaged fasteners.
- Compare the new and original piece by shape, connection diameter, orientation and product numbers.
- Check the condition of connecting hoses, clamps, seals and surrounding plastic parts.
- Before assembly, clean the mating surfaces and remove dirt that could cause leakage.
2) Necessary tools and materials
- Basic set of common hand tools
- Screwdrivers or common tools for loosening fasteners
- Pliers for clips according to the type of attachment
- Cleaning agent suitable for technical parts
- Clean rag or towels
- Work gloves and suitable lighting
3) Step-by-step assembly procedure
- Shut off the engine and allow the engine compartment to cool down safely.
- Ensure access to the removed part and the surrounding parts of the intake.
- Carefully loosen the clips, fasteners, or follow-up connections of the original connection.
- Dismantle the old part so as not to damage the surrounding hoses, plastic parts or connection points.
- Check the downstream parts of the intake for clogging, cracks or other damage.
- Clean the connection surfaces and prepare them for mounting the used part.
- Compare the used part again with the old part just before assembly.
- Place the connection in the correct position without force and without twisting the material.
- Connect all connecting parts so that the connection fits evenly and without tension.
- Ensure the fixings and clips so that the part is firmly attached but does not damage the plastic.
- Check that there are no gaps, leaks or incorrect seating.
- After assembly is complete, visually verify that the part does not interfere with moving or hot surrounding parts.
-
4) Post-assembly checks and test drive/function verification
- After starting, check that the engine runs smoothly and without unwanted intake sounds.
- Check for hissing or other signs of leakage in the suction area.
- After a short test drive, visually check the seat of the part and the strength of the connections again.
- If the problem was caused by a leak in the original part, verify that the defect no longer occurs after the replacement.
5) The most common assembly mistakes + how to avoid them
- Exchanging a similar part – always compare the numbers 9649757480 and 144073 and the connection shape.
- Assembly on dirty bearing surfaces – clean everything carefully before seating the part.
- Excessive stress on the plastic during assembly – do not place the part with force, but in a natural position.
- Leaving damaged clips or connecting parts – check the whole connection, not just the connection itself.
- Insufficient leak check after installation – check again after starting and after a short drive.
Reasons why the part is damaged
- Material aging and normal thermal stress in the engine compartment
- Plastic cracking due to vibration or careless disassembly
- Deformation of joints caused by long-term tension of connected hoses
- Damage during service, especially with careless handling of the intake
- Leaks caused by wear of the abutting edges or fastening parts
