This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98340, 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 the exhaust gas back into the engine's combustion chambers. This process lowers combustion temperatures, thereby minimizing the formation of NOx. A malfunctioning EGR valve can lead to increased emissions, poor engine performance, rough idling, and potential engine warning lights. Replacing a faulty valve with a high-quality unit like this NISSENS part ensures your vehicle meets emission standards and runs smoothly. Engineered for a precise fit and reliable operation, this EGR valve is manufactured to meet or exceed OEM specifications, providing a dependable solution for your vehicle's needs.
