The EGR system is one of the most miss understood system in an engine. It accomplishes many pluses for an engine and keeps detonation in check very efficiently. I do know that tubes plug up that is true. The EGR system is a system that recycles INERT gases back in to the mixture that allows the engineers to control NOX and increase some of the paramaters on the ECM for better mileage and performance. Example a disconnected EGR on lets say a heavy ford with a 302 can ping on 87. But with EGR it is a quiet as a MOUSE. Thanks for listening
