The first EGR-equipped Newell was 688, a 2004 model, after which all Detroit Diesel powered Newells were equipped with EGR valves. The first nine 2004 Newells, 679 through 687, did not have EGR valves. None of the Caterpillar powered Newells have EGR valves, as Caterpillar uses a different technology with a catalytic converter that they refer to as ACERT.
