This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98187, is designed to restore your vehicle's emissions system to its original functionality. The EGR system plays a crucial role in reducing nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gas back into the engine's combustion chambers. A malfunctioning EGR valve can lead to increased emissions, poor engine performance, rough idling, and potential engine warning lights. Replacing a faulty valve with this high-quality NISSENS unit helps ensure your vehicle meets emission standards and runs smoothly. Engineered for durability and precise operation, this EGR valve is built to withstand the demanding conditions of the exhaust system. It is a direct fit, designed to integrate seamlessly with your vehicle's existing EGR system, simplifying the installation process.
