Are you looking for an original catalyst for the Peugeot 206/206+ 1.4 i that fits perfectly and lasts? This used OE part from the PSA concern (CITROËN/PEUGEOT) is exactly for you. It is an original 1731.KS (1731KS), internal code K342, dismantled from a car with a fair mileage of approx. 42,000 km. The ideal solution for auto mechanics and home repairs – no time-consuming tuning of mismatched replacements.

Main advantages
– Original PEUGEOT OE catalytic converter – precise placement, correct efficiency, long service life
– Low mileage 42,000 km – honeycomb without obvious damage, catalytic converter is fully functional
– Quick installation without modifications – fits the serial downpipes and exhaust pipes for the given motorization
– Frequent search by part number: 1731.KS / 1731KS / 1731-KS, internal warehouse code K342

Compatibility
– Peugeot 206 1.4 i 8V (TU3) – typically engines KFW 55 kW, KFV 54 kW, years of production approx. 1998–2009
– Peugeot 206+ 1.4 i 8V (TU3) – years of production approx. 2009–2012
Note: Verify compatibility by VIN, number of lambda probes and exhaust design for your specific year and engine.

Technical information
– Type: three-way catalytic converter for petrol engines (EURO 3/EURO 4 depending on the version)
– Threads for lambda probes: M18x1.5 (most versions with 2 probes – before and after the catalytic converter; check by VIN)
– Location: in the front part of the exhaust system behind the downpipes
– Material: steel casing with ceramic honeycomb
– Designation/OEM: 1731.KS (1731KS, 1731-KS), PSA CITROËN/PEUGEOT, stock code K342
– Designed for: petrol 1.4 i (TU3), not diesel (not FAP/DPF)

Condition and origin
– Used original from a car with ~42,000 km mileage
– No cracks, mechanical damage and no signs of disintegrated honeycomb
– Visually inspected; delivered as in the photos (lambda probes and mounting material only if they are in the photos)

Assembly and tips
– We recommend new gaskets and fasteners
– Before mounting, check the number and location of threads for lambda probes
– A properly functioning catalytic converter can eliminate a P0420 error code if the cause is on the catalytic converter side

Why choose the original 1731.KS
– Exact honeycomb geometry and volume for a given TU3 engine → stable mixture/trims and emissions
– Better resistance to thermal stress than cheap universal substitutes
– Time saving in service – no modifications or compromises

Important
– Always confirm compatibility by VIN and OEM number 1731.KS
– These are used goods; minor cosmetic traces of use do not affect function
– Guarantee of functionality and the possibility of return according to the terms and conditions of the e-shop

Original catalyst (catalytic converter) for Citroën and Peugeot with petrol engines 1.4 VTI and 1.6 VTI. Removed from a car with a raid about 98 000 km. Parts with OEM dog marking guarantee accurate installation and trouble -free assembly into the serial exhaust system, including the correct placement of flanges and threads for Lambda probe.

The catalyst reduces the emissions of unburned hydrocarbons, CO and NOx converted into exhaust gases. A properly functioning unit helps maintain stable emissions and prevents error codes of the control unit (typically P0420 – catalyst efficiency under the threshold). This part is suitable for replacement for worn or mechanically damaged catalyst, or in case of problems with clogging or decay of honeycomb.

Typical symptoms of a defective catalyst are the loss of power, metal rattle from the exhaust, a significant smell of flue gases, the light indicator and the recording of errors related to the catalyst efficiency. Replacing for the original part ensures proper function with ECU factory calibration in VTI engines (EP3/EP6).

Mounting recommendations: Before replacement, let the joints be planted with a release, remove and play the lambda probe into the catalyst threads, always use new seals and fasteners. After assembly, delete the adaptation values ​​and error codes in the control unit, perform a test drive and check of leaks. The approach is usually from the bottom of the vehicle; Recommended use of a workshop jack.

Compatibility: Designed for selected Citroën/Peugeot with 1.4 VTI (EP3) and 1.6 VTI (EP6) engines, eg Citroën C4 II and Peugeot 308.
