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 on your INFINITI is an essential component to the exhaust system. The Catalytic Converter helps regulate emissions by reducing and filtering out toxic pollutants and gases. Without a working Catalytic Converter, toxic fumes from the internal combustion process in the engine could release harmful gases into the environment through the exhaust system. Make sure your INFINITI has a working exhaust system by ordering a new Catalytic Converter from genuine INFINITI Parts.

If your Catalytic Converter is worn out or not working, 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 always mean there is an issue with the Catalytic Converter. If your INFINITI's check engine light is on, connect a scanner to the vehicle's computer to determine the source of the check engine light. Get professional assistance at your nearest authorized INFINITI service center.

Over time, your Catalytic Converter can wear out. It may get clogged or pieces within the Catalytic Converter can break off inside the converter, causing a rattle while you drive. The Catalytic Converter can also be worn out by other problems in your vehicle. These problems can include the engine running too lean and causing the catalytic converter to run hot, or burning oil in your engine. Make sure you rule out other potential issues for a bad Catalytic Converter before replacing it.

If you think your INFINITI's Catalytic Converter is wearing out faster than it should, head to your nearest authorized service center for a full vehicle inspection. Purchase a new, genuine Catalytic Converter from INFINITI Parts and have a professional INFINITI technician install it.
