This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98387, is designed to restore your vehicle's emissions system to its original functionality. A malfunctioning EGR valve can lead to increased emissions, poor fuel economy, and rough idling. This component is engineered to meet or exceed original equipment specifications, ensuring a precise fit and reliable operation. Proper functioning of the EGR system is crucial for reducing nitrogen oxide (NOx) emissions, a significant contributor to air pollution. By recirculating a portion of the exhaust gas back into the combustion chamber, the valve helps to lower combustion temperatures, thereby minimizing NOx formation. This NISSENS valve is built with durable materials to withstand the harsh conditions within the exhaust system, providing a long-lasting solution.
