EGR or Exhaust Gas Recirculation is a system that takes exhaust gas and recirculates it back into the intake air, this does a few things beneficial to the actual running quality of the engine such as: Reduce Combustion Temperatures which dramatically cuts down on Spark Knocking (detonation) which is a common occurance on a high-compression engine such as the LT1, and reduces the NOx (oxides of nitrogen) emissions caused by high compression which fails emission tests.
