Description

Intake air inlet 2.0 16V for Citroën Peugeot cars
It is from a PEUGEOT 307 2.0 16V 130KW

Part description

This intake air inlet connection/throat (intake part) is used to guide air into the engine’s intake system. The main advantage of a used part is its quick availability and significant savings compared to a new original – an ideal choice when repairing an intake, when you need the correct shape and connection without modifications.

The part is designed for the 2.0 16V engine and according to the documents, it comes from the Peugeot 307 2.0 16V 130 kW car. In practice, this type of part is often searched by number, so we list the product codes below.

Installation recommendations

Generally/typically for this type of part (mouth/intake connection) the exact procedure may vary depending on the particular design of the intake and connecting hoses in the given car.

1) Before assembly

• Compare the new and original piece: shape, connection diameters, location of possible outlets and contact surfaces.
• Check the condition of the used part: cracks, deformations, squeezed edges, broken handles, damaged contact surfaces.
• Verify match against part number 9646189780 and possibly 144051.

2) Necessary tools and materials

• Basic set of keys/ratchets and screwdrivers (according to the clips and fixings used)
• Pliers for hose clamps (according to type)
• Degreaser and rag cleaner
• Or new clips/seals if the original ones are tired or damaged

3) Step-by-step assembly procedure

1. Allow the engine to cool and secure the vehicle against movement.
2. Access the suction line (remove the obstructing covers, if any).
3. Mark the position of the hoses/connections so that the installation takes place in the same line as originally.
4. Loosen the clamps on the connecting hoses and carefully pull them off.
5. Unfasten the neck/connection (screws/handles depending on the design).
6. Remove the original part and check the mating surfaces and surroundings for dirt.
7. Clean the connection points and check the condition of the seals/hose flanges.
8. Place the part in place in the correct orientation, without tension or twisting.
9. Connect the hoses as far as they will go and seat them evenly.
10. Tighten the clips so that the joint is tight, but the plastic neck is not deformed.
11. Reinstall any covers and check that nothing rubs against surrounding parts.
• 4) Post-assembly checks and test drive/function verification
  • After starting, check if the intake is sucking in fake air (hissing, unstable idle).
  • Perform a visual inspection of connections and clips with the engine running.
  • After a short test drive, recheck the hoses for seating and tightening of the clips.

  5) The most common assembly mistakes + how to avoid them

  • Incorrect fitting of the hose (in half): always fit all the way and place the clip in the correct groove/position.
  • Pulling the buckle: the plastic may crack – tighten with sensitivity.
  • Ignore cracks or hairline cracks: even a small leak will impair engine performance – inspect the part carefully before fitting.
  • Assembly “in tension”: both the part and the hose must sit naturally, otherwise there is a risk of subsequent rupture.

  Reasons why the part is damaged

  • Plastic aging due to heat in the engine compartment and vibrations.
  • Leaky or overstretched clips that deform the throat over time.
  • Mechanical damage during disassembly/assembly (prying, twisting of hoses).
  • Vibration and tension from badly routed hoses or missing handles.
  • Fouling/oil deposits in the intake, which worsen the tightness and accelerate the degradation of the material.
