This MEAT & DORIA EGR valve, part number 88230E, is designed to regulate the flow of exhaust gases back into the engine's combustion chambers. This process helps to lower combustion temperatures, which in turn reduces the formation of nitrogen oxides (NOx), a major air pollutant. Proper functioning of the EGR system is crucial for meeting emissions standards and maintaining engine efficiency. A faulty EGR valve can lead to poor engine performance, increased fuel consumption, and illuminated check engine lights. MEAT & DORIA is a trusted brand known for its quality automotive components. This EGR valve is manufactured to meet or exceed original equipment specifications, ensuring a reliable fit and consistent performance for your vehicle.
