Description
The Intake Pipe (turbo inlet/air duct) for Citroën and Peugeot 2.0 HDi engines is a critical component that directs filtered air to the turbocharger, ensuring correct boost pressure and efficient combustion. This listing matches part numbers 1400016680 and 143478 and is compatible with RHR 2.0 HDi engines commonly found in Peugeot 807 and Citroën C8. Designed for professional garages and experienced DIYers, the pipe helps maintain engine performance and fuel efficiency when replaced promptly after wear or damage.
Function and Common Failure Modes: The intake pipe delivers the compressed air path between the airbox/intercooler and the turbocharger. Common failure causes include age-related cracking, damage from engine heat cycles, clamps loosening, oil contamination from turbo seals, and physical impacts during repairs. When the pipe leaks or collapses, symptoms typically include loss of boost, uneven power delivery, turbo spool delays, and diagnostic trouble codes related to boost pressure. Regular visual checks and pressure tests during turbo or intake service can reveal issues early.
Replacement And Installation Notes: Replacement is straightforward for a trained mechanic or competent DIYer. Typical steps: loosen and remove clamps at both ends, detach any vacuum lines or sensor connectors, remove the old pipe and inspect adjoining seals and hoses, fit the replacement ensuring correct orientation, secure clamps to manufacturer torque recommendations, and perform a boost/leak test. Use care to avoid over-tightening clamps that could crush the pipe. Expect to spend roughly 30–60 minutes for removal and refit in a workshop setting, depending on vehicle accessibility.
Durability And Maintenance: This intake pipe is not a routine service item but should be inspected whenever the turbo, intercooler, or intake system is serviced. Proper installation and correct clamp selection significantly extend service life. Replacing a damaged pipe promptly prevents further turbocharger wear and potential engine performance degradation.
