Fiat 500 Catalytic Converter

A catalytic converter is a key part of your car catalytic system. It uses a catalyst material to trigger chemical reactions that reduce toxic emissions. Whether you drive a petrol or diesel engine, this component ensures your vehicle meets European emission standards and environmental regulations.

The converter is essential for passing vehicle inspections and helps your Fiat 500 remain safe, compliant, and roadworthy.

Watch out for these symptoms:

• The check engine light turns on, often triggered by the lambda sensor
• Poor fuel economy
• Loss of engine performance
• A strong sulfur or rotten egg smell from the exhaust pipe
• Trouble passing emission tests or MOT inspections

These signs could indicate that your catalytic converter is clogged or deteriorating and needs replacing.

Yes, especially if your model has a manual transmission. Many converters are designed for easy fitting with basic tools and come with a mounting or fitting kit. However, for units integrated into the manifold or those that require welding, it's recommended to have the job done at a garage.

All our converters are delivered with installation guidance and are made for straightforward connection to your original equipment.

To find the correct part, use your registration number or engine code. We stock converters for:

Installing a new catalytic converter helps you:

• Maintain proper emissions levels
• Protect other equipment like the lambda sensor and EGR system
• Pass inspections without delay
• Avoid long-term repair costs

A working converter also improves performance and reduces fuel waste, especially in stop-and-go city driving.

Yes. Petrol vehicles use a three-way catalytic converter that controls CO, HC, and NOx emissions. Diesel engines typically require a diesel oxidation catalyst plus a DPF to trap soot and reduce nitrogen oxide.

At Krosfou, we carry both petrol and diesel versions, including converters suitable for CNG and LPG configurations. All products are EEC type approved and built to the latest Euro emission standards.

We stock both original and OEM-equivalent converters. Each one:

• Matches the original weight, design, and material standards
• Is type approved for European roads
• Includes documentation for registration or inspection purposes

Our focus is on quality without compromising cost-effectiveness.

It's not recommended. Used units may no longer meet approval standards and are often sold without valid documentation. A second-hand cat can lead to MOT failure or performance issues.

A new, tested, and approved converter is the safest choice.

Yes. Every converter we sell meets EEC approval and complies with Euro 4, 5, or 6 emissions standards, depending on your vehicle model. We also stock approved options for other makes, including Ford, Audi, Mercedes, Benz, and HJS.

Whether you drive a Fiat 500 2017 model or a 2013 Fiat Panda, our converters are certified and legal to use throughout Europe, including in the United Kingdom.

A well-maintained catalytic converter should last between 80,000 and 160,000 kilometers. Lifespan can be shortened by poor fuel quality, a faulty lambda sensor, or unburnt fuel reaching the exhaust. Regular inspection of your emission system is key to avoiding early replacement.
