This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98351, is designed to regulate the flow of exhaust gases back into the engine's cylinders. By recirculating a portion of the exhaust gas, the EGR system helps to lower combustion temperatures, which in turn reduces the formation of nitrogen oxides (NOx), a major air pollutant. Proper functioning of the EGR valve is crucial for maintaining engine efficiency and meeting emissions standards. A faulty EGR valve can lead to various performance issues, including rough idling, poor acceleration, increased fuel consumption, and illuminated check engine lights. This NISSENS valve is engineered to meet or exceed original equipment specifications, ensuring reliable operation and a precise fit. Installation of this EGR valve will help restore your vehicle's emission control system to its intended performance. It is manufactured with high-quality materials to withstand the demanding conditions within the exhaust system, providing durability and long-lasting service. Trust NISSENS for quality components that keep your engine running smoothly and cleanly.
