Description
Order a quality used turbo intake hose for 1.6 HDi engines fitted to Citroën and Peugeot models. The intake hose channels pressurised, cooled air from the turbocharger to the engine, helping to maintain boost pressure, improve throttle response and protect fuel economy.
Manufactured from reinforced, heat-resistant elastomer, this hose is designed to withstand engine bay temperatures and turbo boost pressures. As a used OEM-design component, it offers a cost-effective option for restoring reliable turbo operation for both professional workshops and competent DIY mechanics.
Symptoms Of Failure
- Loss of engine power or sluggish acceleration due to boost leaks.
- Whistling or hissing noises from the intake/turbo area.
- Increased fuel consumption and poor throttle response.
- Visible cracks, splits or soft spots on the hose surface.
Replacement Guide
- Ensure the engine is cold and relieve any residual boost pressure.
- Locate the turbo intake hose between the turbocharger/intercooler and the intake manifold or MAF/bypass assembly.
- Loosen and remove hose clamps or quick-release fittings. Keep any reusable clamps for refitment if in good condition.
- Remove the old hose, inspect adjoining pipes, clamps and mating surfaces for damage or oil contamination.
- Fit the replacement hose, orienting it to avoid kinks and ensure correct engagement on both ends. Tighten clamps to secure a leak-free seal.
- Start the engine, check for leaks at idle and under light load, and road-test to confirm restored performance.
Maintenance & Expected Lifespan
Regular visual inspections of the intake hose are recommended, especially on higher-mileage vehicles. Typical causes of failure include heat ageing, oil contamination from charge air leaks or a failing turbo, and mechanical abrasion. Replacing a worn or damaged hose promptly prevents further turbocharger or engine issues and helps maintain fuel efficiency.
