The EGR Valve, or exhaust gas recirculation valve, is one of the many vital pieces in your vehicle’s emissions system. Capturing an amount of the exhaust gasses after combustion and recirculating them through the combustion process once again, the EGR valve repair ensures that every last bit of available fuel is properly burned in the combustion process. This allows the engine to run much more efficiently, using all available fuel for combustion and not allowing any excess fuel or gasses to escape the combustion process and be released into the atmosphere.
