Description
Air Intake Tube – Hose 1.6 HDI 8V for Citroën and Peugeot Vehicles
This replacement air intake tube is designed for the 1.6 HDI 8V engines used across various Citroën and Peugeot models. It restores proper airflow from the airbox to the turbocharger/intercooler or intake tract, helping to maintain engine response, fuel economy and turbo performance. Ideal for professional workshops and DIY mechanics who search by OEM numbers — the part is commonly referenced under the codes 9674942380, 9674951680 and 0382RT.

Fitment And Replacement
Typical fitment locations include the connection between the air filter housing and the turbocharger inlet or intercooler piping on 1.6 HDI 8V engines. Replacement is straightforward for experienced technicians and competent DIYers:
- Allow the engine to cool and work in a well-ventilated area.
- Loosen and remove clamps securing the old hose (screwdriver or socket set) and carefully detach the hose from both ends.
- Inspect mating surfaces (airbox, turbo flange, intercooler) for damage, debris or oil contamination and clean if necessary.
- Fit the new hose making sure it seats fully and without twists or kinks; align clamps over the hose ribs and tighten evenly.
- Start the engine and check for air leaks, abnormal noises or loss of boost. Road-test under light load and verify proper engine response.
Why This Part Fails Most Often
- Aging and Heat Exposure: Rubber and composite hoses harden and crack over time from under-hood temperatures.
- Oil Contamination: Blow-by oil or turbo oil leaks can soften or degrade hose material, leading to swelling or failure.
- Poor Clamping or Vibration: Loose or corroded clamps cause leaks at joints or permit hose movement that accelerates wear.
- Pressure Spikes: Turbo overboost events or clogged intercooler lines can produce stress and cause splits.
Mounting Recommendations
- Use quality stainless-steel worm-drive or T-bolt clamps and replace any corroded hardware.
- Ensure the hose sits without sharp bends, kinks or contact with hot components and that all sealing surfaces are clean.
- Apply a thin film of silicone grease to ease installation if required, but avoid oils that could degrade the rubber.
- After installation, inspect for leaks at idle and under boost; retighten clamps if necessary after a short test drive.
- When replacing intake hoses, also inspect related components (airbox, turbo inlet, intercooler piping, clamps and MAF sensor) for contamination or damage.
