What is a FAP on your Suzuki Alto

As its designation indicates, its role is to filter microscopic particles harmful of your vehicle. These kinds of molecules are so small that they easily fit through your body. For information, it's Peugeot who manufactured the particulate filter. Your catalyst has the role of reducing the dose of particles produced by the engine block, while the FAP collects the remains.
