This MEAT & DORIA EGR valve, part number 88137E, 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 optimal engine performance. A faulty EGR valve can lead to increased emissions, poor fuel economy, rough idling, and potential engine stalling. MEAT & DORIA is a trusted brand known for producing reliable automotive components. This EGR valve is manufactured to meet or exceed original equipment specifications, ensuring a direct fit and dependable performance for your vehicle.
