This NISSENS Exhaust Gas Recirculation (EGR) valve, part number 98174, is designed to restore your vehicle's emissions system to its original functionality. A properly working EGR valve is crucial for reducing nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gas back into the engine cylinders. Over time, EGR valves can become clogged with carbon deposits, leading to performance issues such as rough idling, stalling, and reduced fuel efficiency. This valve is manufactured to meet or exceed OE specifications, ensuring a precise fit and reliable operation. By replacing a faulty EGR valve with this NISSENS unit, you can help ensure your vehicle complies with emissions regulations and maintains optimal engine health. It is engineered for durability and consistent performance under various driving conditions.
