ahhh, actuly you get worse milage but disconecting it is a $6000 fine..., and i mean like 3-5MPG worse...


It recurculates your Exhause gas, HOT Gas back into your intake... how is that good????, the reason for this is to reburn the unburned fuel and particulats...

the egr helps keep combustion temperatures down when your at a steady cursing speed to help cut down on NOx aka oxides of nitrogen
