Turbo Intake Air Inlet Clamp For 1.6 e-HDi For Citroën And Peugeot Vehicles
This genuine replacement clamp secures the turbocharger intake hose on 1.6 e‑HDi engines used in Citroën and Peugeot models. Designed to maintain an airtight connection between the intake hose and the turbo inlet, the clamp prevents boost leaks that cause reduced engine power, rough idling and increased fuel consumption. Suitable for professional workshops and DIY mechanics, this part is often searched by its product numbers 9684362180 and 1434G3.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C3 Picasso; Citroën C4 II; Citroën C4 Picasso; Peugeot 3008 I; Peugeot 308; Peugeot 5008 I
- Product Codes: 9684362180, 1434G3
- Other Numbers: 1.6 e-HDi
Function
The clamp fastens the turbo intake hose to the turbocharger inlet, creating a pressure-tight seal that carries compressed air from the intercooler to the engine. A secure clamp prevents loss of boost pressure and ensures correct air metering for the engine management system.
Replacement Guide
- Allow Engine To Cool Completely Before Work.
- Loosen The Existing Clamp And Carefully Remove The Intake Hose From The Turbo Inlet.
- Inspect The Hose End And Turbo Inlet For Cracks, Oil Deposits Or Distortion; Replace Any Damaged Hoses.
- Fit The New Clamp Over The Hose And Position It Evenly On The Turbo Inlet Flange.
- Tighten The Clamp Gradually Until The Hose Is Secure—Avoid Over-Tightening To Prevent Damage To The Hose Or Turbo Inlet.
- Start The Engine And Check For Boost Leaks Under Load; Recheck Tightness After A Short Test Drive.
Installation Recommendation
Use Tools Suitable For Hose Clamps And Apply Even Pressure When Tightening. Replace Any Worn Or Brittle Intake Hoses Simultaneously To Ensure Long-Term Seal Integrity. For Best Results, Inspect The Entire Turbo Induction System (Intercooler Pipes, Hoses, Clamps) During Installation.
Why This Part Fails Most Often
Clamps fail primarily due to prolonged heat cycles, oil contamination and mechanical fatigue. Rubber hoses can harden or crack with age, allowing the clamp to slip or the seal to deteriorate. Loose or corroded clamps also permit boost leaks, which are frequently discovered during turbocharger servicing or after oil leakage into the induction tract.
Notes For Mechanics And DIYers
This clamp is an essential small component that directly affects turbo system performance. It is commonly replaced during turbo or intercooler maintenance and whenever boost leaks are diagnosed. Keep spare clamps and inspect all related hoses when any indication of decreased boost or engine hesitation appears.
