The EGR valve reduces nitrogen oxide emissions by recirculating a portion of exhaust gases back into the engine intake manifold. 1S7G9D475AG 1S7G9D475AL Electric EGR Valve Exhaust Gas Recirculation Valve For For Mondeo For Focus For Escape For Fusion For Transit For C-Max For EcoSport. Reduced exhaust pollutants: Introducing some exhaust gas into the intake manifold and back into the cylinder lowers combustion temperature, reducing nitrogen oxide emissions. Robust & Durable: Manufactured from materials capable of withstanding heavy loads, it contributes to improved vehicle stability and responsiveness. Exhaust gas dilutes the air-fuel mixture, reducing combustion intensity, resulting in smoother operation., Manufacturer: zeshibai
