I see four possible locations to fit an EGR plate: (1) On the rear of the exhaust manifold, (2) On the EGR valve housing inlet, (3) on the EGR valve housing outlet, and (4) on the inlet manifold --from the EGR valve housing outlet.
So which is OK, which will create problems, and which will not "work"
It seems to me the rear of the exhaust manifold makes sense--maybe heat issues??
Thanks
