Description
Intake turbo hose, air connection for 1.6 HDi engines for Citroën and Peugeot vehicles.
Product Description
This replacement turbo intake hose is designed for 1.6 HDi engines used in a range of Citroën and Peugeot models. It connects the turbocharger inlet to the air intake tract, ensuring stable boost pressure and uninterrupted airflow to the engine. Manufactured to match OE fitment and dimensions, the hose helps restore proper turbo response and prevents boost leaks that cause loss of power, rough idling or turbo noise.
Key Benefits
- Direct fit for Citroën and Peugeot 1.6 HDi applications — quick swap for workshop or DIY repair.
- Restores correct boost pressure and throttle response.
- Durable construction resistant to heat and oil contamination compared to degraded original hoses.
- Compatible with common OE reference numbers to simplify parts lookup.
Function And Symptoms Of Failure
The turbo intake hose routes compressed air from the turbocharger to the intake system. Its role is crucial: any crack, split or loose clamp causes boost leaks that result in reduced engine performance, increased smoke or poor fuel economy. Typical symptoms of a failing hose include whistling or hissing noises under load, intermittent loss of power, rough acceleration, and diagnostic trouble codes related to boost or mass air flow readings.
Common Causes Of Damage
- Aging And Material Fatigue: Rubber and silicone components harden and crack after prolonged exposure to heat and oil vapor.
- Oil And Soot Contamination: Oil deposits from the turbo or PCV system accelerate material degradation.
- Improper Clamping Or Loose Connections: Missing or worn clamps allow movement and accelerated wear.
- Excessive Boost Pressure Or Overboost Events: Sudden pressure spikes can split weakened hoses.
Replacement And Installation Notes
Replacing the turbo intake hose is a straightforward job for an experienced technician or a competent DIYer. Typical steps:
- Park the vehicle on a level surface and allow the engine to cool.
- Remove any engine covers or intake ducts obstructing access to the hose.
- Loosen the clamps at both ends of the hose and carefully detach the hose from the turbo outlet and intake pipe.
- Inspect the turbo outlet, intake pipe and mating surfaces for oil buildup, cracks or debris and clean as required.
- Fit the new hose, position clamps correctly and tighten evenly to the recommended clamp torque or until secure — avoid over-tightening that can damage hose ends.
- Reassemble removed components, start the engine and check for leaks under load (listen for hissing, check boost stability).
Recommended Additional Work: Replace old clamps with new high-quality worm-drive or T-bolt clamps, and inspect intercooler hoses and connections for concurrent wear.
Inspection Interval
There is no fixed interval for replacement. Inspect the hose visually at every major service and whenever symptoms of boost loss or reduced performance occur. Replace at the first sign of cracking, soft spots or oil saturation to prevent secondary damage to the turbocharger or engine management system.

Why This Part Is Worth Replacing
A damaged turbo intake hose directly affects engine performance and drivability. Replacing a worn or leaking hose is one of the most cost-effective repairs to restore turbo function, improve fuel economy and prevent more expensive repairs to the turbocharger or intake sensors.
