2009-2011 Buick Lucerne 3.9L V6 Catalytic Converter – Bank 1

Three-way catalytic converter is also commonly called catalyst. The catalyst itself is a special chemical mixture that is used to accelerate the rate of chemical reactions in the medium, while the elements or components of the catalyst itself do not produce any chemical changes. The catalyst must be reliably coated on the surface of the honeycomb holes of the ceramic carrier by using certain complex processes such as dipping and drying.
