I have them plugged on the GN and the hoses still hooked up on the TTA. I don't see any difference that's for sure.. I guess it's a mind trick that makes you think all this heat is being transfered around the tb! :dunno: :cheers:
And on cars like the 5.0 87-92 Mustangs guys disconnected their lines ignoring the fact that the egr plate was sandwiched between the manifold and throttle body. On those cars the coolant lines was to take the heat away, because of the EGR.....alot removed them thinking they were cooling it..
