Description
Air Intake 1.4 HDI 16V 8HY For Citroën And Peugeot Vehicles
Product Overview
This air intake distribution piece is designed for the 1.4 HDi 16V (engine code 8HY) diesel engines used on selected Citroën and Peugeot models. It routes and balances induction air between turbocharger/intercooler plumbing and the intake manifold, contributing to smooth engine response and correct boost behaviour. Replacement part numbers commonly searched for: 9647250480, 0361L4 (also listed as 0361.L4).
Key Benefits
- Direct fit for vehicles equipped with the 1.4 HDi 16V 8HY engine — quick replacement for workshop or DIY repairs.
- Restores proper air routing to eliminate boost leaks, rough idle and loss of power associated with damaged intake distribution components.
- Often sold under original equipment part numbers for straightforward parts lookup.

Installation Recommendations
Recommended for professional fitment or experienced DIY mechanics. Basic replacement steps:
- Disconnect the negative battery terminal before starting work.
- Release intake system pressure and remove any clamps and hoses connected to the distribution piece (turbo/intercooler hoses, PCV lines if present).
- Unbolt the intake distribution from its mounting points, noting bolt locations and any brackets or sensors.
- Replace any sealing gaskets or O-rings with new items to ensure leak-free joints.
- Refit hoses and clamps, then reconnect the battery and verify there are no air leaks or fault codes. Run the engine and check for normal boost response.
Use manufacturer torque settings for fasteners and ensure hose clamps are tightened evenly to avoid deformation. Replace any brittle vacuum hoses or cracked clamps found during the job.
Most Common Failure Causes
Failures are usually caused by age-related degradation of plastic or rubber sections, heat and vibration leading to cracks, or damaged sealing surfaces and O-rings. Build-up of oil vapour and soot from the crankcase ventilation system can accelerate wear. A failing intake distribution commonly produces boost leaks, rough idle, reduced power, and occasional turbo lag.
Service Life And Practical Notes
Life expectancy varies with usage and environment; on high-mileage or older vehicles the part may fail more frequently. Inspect the intake distribution during routine maintenance, especially if the vehicle shows symptoms of air leaks or decreased engine performance. When replacing, always use the correct part numbers for a reliable fit and restore original air routing and sealing.
