Description
Inlet Hose Clamp for Turbo Air Intake 1.6 e-HDI for Citroën and Peugeot Vehicles.
This OE-fit inlet hose clamp secures the turbo air intake connection on 1.6 e-HDI engines used in Citroën and Peugeot models. Designed to maintain an airtight seal between the turbocharger inlet and the intake hose, the clamp prevents boost leaks that reduce engine performance, increase fuel consumption, and cause erratic turbo response. Suitable for professional workshops and experienced DIY mechanics, this part is commonly searched by part numbers 9684362180 and 1434G3 — use these codes to quickly find the correct replacement.
Key Benefits
– Ensures a reliable, airtight connection on the turbo inlet to preserve boost pressure and engine response.
– Direct replacement for vehicles using OEM codes 9684362180 / 1434G3.
– Simple, fast fitment that can be performed in a standard workshop or by a competent DIYer.

Function
The clamp fastens the turbo inlet hose to the turbocharger housing or intake pipe, creating a pressure-tight joint. It must withstand thermal cycles, engine vibrations and occasional oil contamination while maintaining consistent clamping force to avoid boost leakage.
How To Replace
Basic replacement steps for qualified mechanics or experienced DIYers:
- Let the engine cool to avoid burns from hot components.
- Relieve any residual boost pressure by cranking the engine briefly or following manufacturer guidance.
- Loosen the existing clamp screw or release the clamp type fitted; slide the clamp away from the joint.
- Inspect the intake hose and mating surfaces for cracks, swelling, oil contamination or deformity; replace the hose if necessary.
- Position the new clamp so it sits evenly over the hose bead and mating flange; tighten gradually and evenly.
- Tighten to the vehicle manufacturer’s specification where available — avoid over-tightening to prevent cutting into the hose or deforming the inlet flange.
- Start the engine and check for boost leaks, unusual noises or loss of performance; re-check clamp tightness after a short test drive.
Recommended Installation
- Use the identical clamp type and size as the original (OE codes listed above) to ensure correct fit and sealing.
- Replace any damaged or oil-soaked hoses; clamps cannot reliably seal on degraded rubber or silicone.
- Use appropriate tools (screwdriver, nut driver, or torque wrench when a torque value is specified) and avoid using excessive force.
- Perform a final leak check under boost with the engine at operating temperature.
Why This Part Commonly Fails
Clamps on turbo inlet hoses typically fail due to long-term exposure to heat cycles, corrosion of the metal band or screw, vibration-induced loosening, and oil contamination that degrades the hose material. Improper installation or repeated overtightening can also damage the hose bead and lead to leaks. Regular inspection during scheduled maintenance helps catch early signs of wear before performance is affected.
