What is the expected lifespan of a catalytic converter?

The expected lifespan of a catalytic converter is typically around 10 to 15 years under normal operating conditions. This range is based on the design and materials used in catalytic converters, which are engineered to withstand the extreme temperatures and chemical reactions occurring in the exhaust system.

In this context, the catalytic converter works to reduce harmful emissions from internal combustion engines by converting them into less harmful gases. Over time, factors such as vehicle maintenance, driving conditions, fuel quality, and the presence of other issues like engine problems can impact its longevity. However, with proper care and maintenance, a catalytic converter can effectively last within this 10 to 15-year range, making it the most accurate choice among the provided options based on typical vehicle usage and wear.
