Understanding Your 2008 BMW Catalytic Converter
The 2008 BMW catalytic converter serves as the exhaust system’s core emissions control component, transforming harmful gases into less toxic compounds via a honeycomb catalyst structure described in catalytic converter fundamentals. Exhaust from high-performance engines such as the E60 535d flows through a catalyst substrate that reduces hydrocarbons, carbon monoxide, and nitrogen oxides, ensuring compliance with EU emission standards and enhancing engine longevity.
