This NISSENS Radiator and Exhaust Gas Recirculation (EGR) system, part code 989313, is designed to maintain your vehicle's optimal operating temperature and reduce harmful emissions. The radiator plays a crucial role in dissipating heat generated by the engine, preventing overheating and potential damage. NISSENS radiators are engineered for efficient heat transfer and durability, ensuring reliable performance under various driving conditions. The integrated EGR system helps to reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gas back into the engine cylinders. This process lowers combustion temperatures, significantly contributing to a cleaner exhaust and compliance with environmental regulations.
