Catalytic converter parts are essential components of a vehicle's exhaust system. They are responsible for reducing harmful emissions and converting them into less harmful byproducts. These parts are designed to convert pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons into carbon dioxide, nitrogen, and water vapor. Catalytic converter parts are made up of a ceramic or metallic substrate coated with a precious metal catalyst. The catalyst reacts with the exhaust gases to facilitate the chemical conversion process. These parts are crucial for ensuring that vehicles comply with emissions regulations and contribute to a cleaner environment.
