Fitment And Compatibility

Fits Citroën C1 and Peugeot 107 equipped with the 1.0 i 1KR engine (50 kW). Always compare the product codes listed above with the part number you are replacing to ensure correct fitment.

Installation Recommendations

Recommended for installation by an experienced mechanic or competent DIY-er with the right tools. Typical replacement steps:

• Allow the exhaust to cool thoroughly before starting work to avoid burns.
• Raise and safely support the vehicle to access the exhaust manifold.
• Disconnect the oxygen sensor(s) and remove heat shields to expose the manifold flange.
• Unbolt the manifold-to-head and manifold-to-downpipe connections; inspect studs and nuts and replace if corroded.
• Replace exhaust gaskets and any sealing hardware during reassembly to ensure a gas-tight joint.
• Use anti-seize on sensor and fastener threads where appropriate and torque bolts to the manufacturer’s specification.
• After installation, check for exhaust leaks, proper sensor operation and correct engine running.

Why This Part Fails

Catalytic converters can fail or become ineffective for several common reasons: prolonged exposure to unburned fuel (resulting from misfires or a rich running condition), contamination by engine oil or coolant, thermal shock from overheating, or physical damage from road debris. Excessive soot buildup or internal substrate breakage can cause clogging, increased backpressure and loss of performance. Addressing the root engine issue (misfires, oil consumption, coolant leaks) is essential to prevent repeat failures.

Notes For Buyers

This is a used OEM component from a low-mileage donor vehicle. It is suitable for professionals and skilled DIY mechanics seeking a cost-effective, direct-fit replacement. Verify part numbers against your original part to confirm compatibility.

Product Overview

High-quality used exhaust manifold with an integrated catalytic converter designed for Citroën C1 and Peugeot 107 fitted with the 1.0 i (50 kW) engine. This complete manifold/catalyst assembly includes the substrate and flange ready for direct replacement on compatible vehicles. The unit retains original OEM fitment and mounting points, making it a practical and cost-effective repair option for workshops and experienced DIYers.

Why Choose This Catalytic Converter

• Direct fit for specified models — reduces modification time and avoids custom exhaust work.
• Includes integrated manifold for simplified installation compared with separate pipe-mounted converters.
• OEM part numbers listed for easy matching with service manuals and parts catalogs.
• Suitable for mechanics and knowledgeable DIY technicians looking for a reliable replacement at a lower cost than new OEM parts.

Function And Symptoms Of Failure

The catalytic converter reduces harmful emissions by converting CO, HC and NOx into less harmful gases. When the catalyst is failing or clogged, common symptoms include reduced engine performance, loss of power under load, increased fuel consumption, rattling noises from the converter body, and sometimes a persistent check engine light with fault codes related to catalyst efficiency or backpressure.

Typical Lifespan And Common Causes Of Failure

Catalytic converters generally last many tens of thousands of kilometers, often exceeding 100,000 km under normal conditions. Failures can occur earlier due to factors such as chronic rich running or misfires (which overheat or melt the ceramic substrate), contamination from oil or coolant, physical damage from road debris or corrosion, and thermal shock from rapid cooling of a very hot catalyst. Incomplete combustion or long idling periods can accelerate clogging.

Installation Recommendations

• Prepare the vehicle: Work on a cooled exhaust system; raise and support the vehicle safely. Use penetrating oil on fasteners if needed.
• Replace Gaskets And Fasteners: Always fit new exhaust gaskets and use the correct grade of bolts/nuts where required. Exhaust flange hardware is often seized — inspect and replace as necessary.
• Oxygen Sensor Handling: If an O2 sensor is fitted to the manifold, remove it carefully and reinstall or replace with the correct sensor. Apply anti-seize on sensor threads where appropriate, avoiding contamination of the sensor tip.
• Verify Engine Health: Resolve underlying engine issues (misfires, rich running, oil/coolant leaks) before fitting the new converter to prevent immediate recontamination or damage.
• Tightening And Alignment: Align flanges before final torque and follow the vehicle manufacturer’s torque specifications from the workshop manual. Check for exhaust leaks after installation.
• Recommended For: Professional fitment by a workshop or experienced DIY technicians with appropriate tools (jack stands, torque wrench, O2 sensor socket).

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C1; Peugeot 107 — 1.0 i 50 kW (engine family 1KR)
• Product Codes: 0342L3; 1608916280; 1688263080
• Additional Numbers: Removed From Vehicle With Approx. 68,000 Km

Most Common Reason For Failure

The most frequent cause of premature catalytic converter failure is engine-related issues that allow unburned fuel or oil to enter the exhaust (misfires, worn ignition components, fuel system faults, or oil burning). This leads to overheating, substrate melting or contamination and eventual clogging or internal breakage.

Notes For Purchasing

Match the listed product codes with the vehicle’s parts catalog or service literature to confirm compatibility. The listed unit is a used original equipment assembly removed from a vehicle at approximately 68,000 km; visual inspection for external damage and sensor threads is recommended before installation.

If you are looking for a reliable and high -quality catalyst designed for Citroën C1 and Peugeot 107 with 1.0 I (50 kW), you are in the right place. This catalyst comes from a car, which has only 98,000 km, which testifies to its low wear and longer expected lifetime. Catalysts play a key role in reducing the emissions of harmful substances blown from the engine, and their correct functionality is necessary to meet emission standards and to ensure optimum vehicle performance.
