THREE Way Catalytic Converter.
Catalytic Converter.

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

The Catalytic Converter is an integral part of your INFINITI's exhaust system. The Catalytic Converter controls emissions by filtering out and reducing toxic gases and pollutants from the exhaust. Without a functioning Catalytic Converter on your INFINITI, toxic fumes from the internal combustion process in the engine could release harmful gases into the environment through the exhaust system. Ensure the exhaust system on your INFINITI is working like it should with a new, genuine INFINITI Catalytic Converter.

If your Catalytic Converter is worn out or not working, you may notice a few 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, a malfunctioning Catalytic Converter can cause your INFINITI's check engine light to display. However, the check engine light may not always signify there's something wrong with the Catalytic Converter. If your INFINITI's check engine light is on, connect a scanner to the vehicle's computer to determine the cause of the malfunction indicator light. Your nearest authorized INFINITI service center can help.

Over time, your Catalytic Converter can wear out. It can get clogged or pieces within the Catalytic Converter can detach and cause a rattling sound inside the converter while you drive. Other issues on your vehicle may cause the Catalytic Converter to wear out as well. These problems can include the engine running lean, causing the Catalytic Converter to run hot, or the engine burning oil. Make sure you rule out other potential issues for a bad Catalytic Converter before replacing it.

If you suspect the Catalytic Converter on your INFINITI isn't lasting as long as it should, head to your nearest authorized service center for a full vehicle inspection. Get a new Catalytic Converter from genuine INFINITI Parts and have a professional INFINITI technician install it.
