Your better off leaving as is.... unless you plan on blocking the gap
by removing the SMIC you change the flow of air going through the radiator. Basically the physics theory of following the path of least resistance. Meaning air will funnel through the gap instead of through your radaitor!!
Also the NON turbo full length radiators is a bad idea. Mainly cause they were not designed for boost. Early on it was a popular swap, that ended when they started blowing holes inthem from the pressure, or cars started overheating from the lack of cooling efficiancy.
Best option Corksport Full length thicker radiator. They are affordable through PG and work perfect..Plus they have major bling factor!!!
Emespea: I don't know where you got that info but it's wrong...
I run a MAM FMIC and it DOES NOT travel anywhere near the SMIC used to be housed. The MAM actually travels up under the fog light then turns up through the drivers side fender up through the hole that most CAIs use inbetween the battery and the engine to the intake mani.
