Description
Turbo Intake Hose 1.2 THP
For Vehicles Citroën, Peugeot, Toyota, Fiat, Opel
Overview
High-quality replacement turbo intake hose for 1.2 THP petrol engines. Designed to carry pressurised boost air between the turbocharger and the intake tract, this hose restores proper boost delivery, prevents air leaks and helps maintain engine performance and fuel efficiency. Ideal for professional mechanics and experienced DIY enthusiasts working on Citroën and Peugeot models equipped with the 1.2 THP engine family.
Key Benefits
- Direct fit for listed applications — simple swap with original routing and connections.
- Durable construction resistant to oil, heat and vibration from the engine bay.
- Helps eliminate boost leaks that cause loss of power, poor throttle response and increased fuel consumption.
- Supplied with or compatible with standard worm-clip or Oetiker-style clamps (replace clamps as needed).

Function And Failure Modes
The turbo intake hose transports compressed air from the turbocharger into the intercooler or intake manifold. It must withstand high temperatures, pressure fluctuations and exposure to engine oil and road contaminants. Common causes of failure include material ageing and cracking, oil saturation causing softening, clamp or connection failure, and mechanical damage from incorrect routing or contact with hot components. A failing hose typically leads to loss of boost pressure, reduced engine power, rough idle and possible diagnostic trouble codes related to airflow.
Replacement Guidance
Replacement is straightforward for a qualified mechanic or experienced DIYer with basic tools. General steps:
- Allow Engine To Cool. Work only on a cold engine to avoid burns and to prevent damage to components.
- Loosen And Remove Clamps. Remove clamps or clips securing the hose at both ends (turbocharger outlet and intercooler/intake connection).
- Remove Old Hose. Inspect mating surfaces for oil residue, debris or damage and clean before fitting the new part.
- Fit New Hose. Ensure Correct Orientation And Full Engagement On Both Ends. Use New Clamps If Possible And Secure Evenly.
- Check For Leaks. Start The Engine, Allow It To Reach Operating Temperature, Then Inspect For Boost Leaks Under Load (Short Road Test Recommended).
When replacing the hose, inspect adjacent components (turbo outlet, intercooler pipes, clamps and vacuum lines) and replace any worn clamps or damaged pipes to ensure a durable repair.
Recommended Maintenance Interval
There Is No Fixed Service Interval For Turbo Hoses. Replace On Visible Signs Of Wear, Cracking, Oil Soaking Or When Experiencing Symptoms Such As Loss Of Boost, Poor Acceleration Or Unstable Idle.
Why This Part Fails Most Often
Heat Cycling And Age: Repeated heating and cooling in the engine bay leads to hardening, cracking and eventual rupture. Oil Contamination: Oil carried from the turbo can soften or degrade the rubber compound. Mechanical Stress: Incorrect clamps, tight bends or rubbing against engine components accelerate wear. Road Debris Or Impact Can Also Cause Tears Or Perforation.
