This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98201, 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 cylinders. This process lowers combustion temperatures, thereby minimizing the formation of NOx. When the EGR valve malfunctions, it can lead to increased emissions, poor engine performance, rough idling, and potential check engine lights. Replacing a faulty EGR valve with a quality component like this NISSENS unit ensures your vehicle meets emission standards and runs smoothly. Engineered for a precise fit and reliable operation, this EGR valve is built to withstand the demanding conditions of the exhaust system, providing a durable and effective solution for your vehicle's needs.
