The NISSENS Exhaust Gas Recirculation (EGR) Valve, part number 98404, is engineered to precisely control the amount of exhaust gas recirculated into the intake manifold. This process is crucial for lowering combustion temperatures, which in turn significantly reduces the formation of harmful nitrogen oxides (NOx) emissions. By managing exhaust gas recirculation, this valve contributes to a cleaner combustion process and helps your vehicle meet environmental standards. It also plays a role in optimizing engine performance and fuel economy under various driving conditions. Crafted with quality materials and precision engineering, the NISSENS EGR valve ensures reliable operation and durability. Proper functioning of the EGR system is essential for maintaining engine health and preventing issues like poor idling, stalling, or increased emissions.
