Description
Filter box for Citroën and Peugeot vehicles with 1.6 e-HDi engines.
Direct-fit filter box replacement for 1.6 e-HDi diesel engines, matching OEM references 9673061080 and 1420V1. Designed for professional workshops and experienced DIY mechanics who search by part number — this airbox restores proper intake routing, protects the air filter element and helps maintain engine performance, fuel economy and reliable sensor readings. Installing the correct filter box reduces the risk of unmetered air entering the engine, prevents premature air filter wear and eliminates intake leaks that can trigger fault codes or rough running.

Fitment And Replacement Procedure
Replacement is straightforward for a trained technician or experienced DIY mechanic. Typical steps:
- Park vehicle on level ground and allow engine to cool. Follow vehicle manufacturer safety guidance.
- Release clamps on intake hoses and detach any vacuum lines or breather hoses connected to the airbox.
- Unplug electrical connectors (e.g. MAF sensor) if mounted on the airbox — label connectors to ensure correct reassembly.
- Remove mounting screws or clips securing the airbox and lift out the old unit with the air filter element.
- Transfer any sensors or fittings to the new airbox if required, fit new gaskets or seals where supplied, then install the new unit and reattach hoses and connectors.
- Start engine and check for intake leaks, ensure secure hose clamps and correct sensor operation.
Installation Recommendations
Wear suitable personal protective equipment and work in a well-ventilated area. Inspect the air filter, intake hoses, clamps and MAF sensor during replacement. Replace any brittle hoses or damaged clamps to avoid future leaks. Ensure connectors are clean and properly seated; if the MAF sensor is disturbed, check its condition and clean only with manufacturer-recommended cleaner if necessary. Always follow the vehicle manufacturer’s torque and reassembly instructions.
Most Common Failure Reasons
Airboxes usually last many years, but common causes of failure include physical damage from impacts, degraded or broken mounting clips, heat-induced cracking, and improper previous repairs. Damage or poor sealing allows unmetered air into the intake, which can cause rough idling, reduced performance and incorrect sensor readings. Regular visual inspection during routine maintenance helps detect damage early.
