YES strange the Cobra inlet doesn't have this..
I guess its for all invironments. It heats it but on the other hand stops it from getting too hot.. Keep in mind thats not the reason EGR is used.Its put through into combustion chamber to DROP chamber temps and help cat exhaus temps rising..I guess pre burnt gas can't burn again.. This way i prevents detonation, heat, by advancing spark up to 50* it helps engine pass epa due to long burn n part throttle etc .. The EGR only opens at clossed & part throttle so there's no performance gain by disconnecting it...Infact it can cause detonation by preventing it from working... By retarding timing to prevent detonation is very much going to bring performance down somewhat!!!!

Actually EGR operates from medium cruise to heavy acceleration and cut's down on NOx gases. The coolant is there to Cool the intake down where the hot exhaust gases are flowing in.
You will notice poorer fuel economy if you disconnect EGR mainly because under warm cruise the unburnt fuel will not get recirculated and burnt up but also because if the EVP picks up no EGR valve movement it will not advance the timing in anticipation of a more difficult to burn, exhaust contaminated inlet charge and will also not reduce the fuel injection pulse for the less oxygenated air.
