Description
Turbo hose, intake air resonator 1.6 HDI for Citroën and Peugeot vehicles.
This intake resonator hose is designed for the 1.6 HDI turbocharged engines used in select Citroën and Peugeot models. It damps intake noise, smooths pressure pulses in the intake tract and helps maintain consistent airflow to the turbocharger and charge-air system. A correctly fitting resonator contributes to quieter operation, more stable turbo response and can prevent air leaks that would otherwise cause rough idling or reduced engine performance.
Key Benefits
Engineered for direct replacement on compatible 1.6 HDI applications, this resonator hose provides reliable fitment and restores original air path geometry. Replacing a worn or cracked resonator reduces intake leaks, eliminates whistling or hissing noises under boost and helps sensors read stable intake conditions—important for timely turbo spool-up and consistent fueling.
Compatibility
Fits vehicles equipped with 1.6 HDI engines. Common applications include:

Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: 1.6 HDI (examples: Citroën C5, Peugeot 407)
- Product Codes: 9653777780, 144057, NFP
- Other Numbers: 144057, 9653777780
Installation Recommendations
Intended for fitment by professional technicians or experienced DIYers. General replacement steps:
- Allow the engine to cool before beginning work to avoid burns from hot components.
- Locate the resonator in the intake/charge-air plumbing on the 1.6 HDI engine; typically between the airbox/turbo inlet and downstream intercooler/intake manifold.
- Loosen and remove clamps or clips securing the old hose, then carefully detach any connected pipes or sensors if present.
- Inspect adjoining pipes, clamps and mating surfaces for damage, oil contamination or deformation; replace clamps if worn.
- Install the new resonator hose, ensure correct orientation and full seating on mating spigots, then secure with appropriately sized clamps. Tighten clamps evenly—avoid over-torquing plastic fittings.
- Start the engine and check for leaks, abnormal noises and proper turbo response. Re-check clamps after a short test drive.
Use appropriate hand tools and personal protective equipment. If clamps are rusted or seals are degraded, replace them during installation to ensure long-term reliability.
Why This Part Fails
Resonator hoses commonly fail due to age-related degradation of rubber or silicone (hardening, cracking), prolonged exposure to heat cycles, oil contamination from turbocharger seals or crankcase ventilation, and mechanical wear from vibration. Clamps can loosen or corrode, allowing leaks to develop. When a resonator leaks, symptoms often include increased intake noise, intermittent turbo lag, unstable idle or diagnostic trouble codes related to air metering.
Notes For Buyers
This part is frequently searched by its reference numbers (9653777780, 144057). If your vehicle uses a 1.6 HDI engine and exhibits intake noise or poor boost behavior, replacing a degraded resonator hose is a cost-effective first step. Add this item to your cart to restore proper intake integrity and quiet operation.
