ACDelco Gold EGR Valves

ACDelco Gold replacement exhaust gas recirculation valves help you get maximum fuel efficiency and power from your engine. A properly operating EGR valve is an essential component in vehicle performance. The EGR valve is the main emissions control component in the exhaust gas recirculation system. Located on the intake manifold, it opens a small passageway between the exhaust and intake manifolds to allow a metered amount of exhaust to flow back into the engine. This reduces combustion temperatures and helps to control the formation of oxides of nitrogen (NOx). The EGR valve is opened by the application of vacuum to its control diaphragm--or on new engines, the valve is electronic and uses a solenoid or a small stepper motor to operate.
