Womala EGR Valve 11717804378 11718479605 Exhaust Gas Recirculation Valve for BMW

Product Details: EGR Valve (Exhaust Gas Recirculation Valve) - 11717804378

This Exhaust Gas Recirculation (EGR) valve is a precision-engineered emissions control component designed to reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gases back into the engine intake manifold . It ensures optimal engine performance, fuel efficiency, and compliance with emissions standards.

Core Function: The EGR valve regulates the flow of exhaust gases into the combustion chamber, lowering combustion temperatures and reducing harmful NOx emissions . A properly functioning EGR valve is essential for smooth engine operation, preventing knocking, and maintaining fuel economy. Symptoms of a failing EGR valve include poor/rough idling, black smoke from exhaust, illuminated check engine light, reduced fuel economy, and engine stalling .
