THREE Way Catalytic Converter.

• Essential part of your exhaust system
• Helps control emissions by filtering and reducing pollutants
• Replace when failing or worn out

Your INFINITI's Catalytic Converter is an important part of your vehicle's exhaust system. The Catalytic Converter controls emissions by filtering and reducing pollutants and toxic gases. If your Catalytic Converter isn't working properly on your INFINITI, toxic fumes from the internal engine combustion process could allow harmful gases to exit the exhaust system into the environment. Make sure your INFINITI has a working exhaust system with a new, genuine INFINITI Catalytic Converter.

If your INFINITI has an old or worn out Catalytic Converter, you might notice some symptoms, such as darker exhaust smoke, slow engine performance, reduced acceleration, a sulfuric or rotten egg smell from coming from the exhaust, or excessive heat from underneath your INFINITI.

Additionally, an issue with the Catalytic Converter in your INFINITI can trigger your vehicle's check engine light. However, the check engine light doesn't necessarily mean there's a problem with the Catalytic Converter. If the check engine light is on in your INFINITI, scan the vehicle's onboard computer for error codes to determine the source of the check engine light. Get professional assistance at your nearest authorized INFINITI service center.

Your Catalytic Converter can wear out over time. It may get clogged or pieces within the Catalytic Converter can detach and cause a rattling sound inside the converter while you drive. Additionally, other problems in your INFINITI can cause the Catalytic Converter to wear out. These problems may include the engine running lean, causing the Catalytic Converter to run hot, or the engine burning oil. It's important to ensure there are no additional issues causing the Catalytic Converter to wear out.

If you think your INFINITI's Catalytic Converter is wearing down quicker than it should, get a vehicle inspection at your nearest authorized INFINITI service center. Get a new Catalytic Converter from genuine INFINITI Parts and have it installed by a professional INFINITI technician.
