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. Your INFINITI's Catalytic Converter helps limit emissions by reducing and filtering out toxic pollutants and gases. Without a working Catalytic Converter, toxic fumes from the engine combustion process could allow harmful gases to exit the exhaust system into the environment. Ensure the exhaust system on your INFINITI is working like it should with a genuine Catalytic Converter from INFINITI Parts.

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

Additionally, a malfunctioning Catalytic Converter can cause the check engine light to display on your dashboard. However, an illuminated check engine light doesn't always mean there is an issue with the Catalytic Converter. If your INFINITI is showing the check engine light, connect a scanner to the vehicle's computer to find out what is triggering the check engine light. Your nearest authorized INFINITI service center can help.

Your Catalytic Converter can wear out over time. It may become clogged or small parts inside 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 may include the engine running too lean and 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 think your INFINITI's Catalytic Converter is wearing out faster than it should, get a vehicle inspection at your nearest authorized INFINITI service center. Purchase a new, genuine Catalytic Converter from INFINITI Parts and have a professional INFINITI technician install it.
