um when i used to have an pulsar et turbo when i was 16 my a few ppl would place small fans on their intercooler for that exact reason. it is a benefit by cooling it down by some degree BUT i beleive this is better used for a intercooler that is engine mounted or mounted in the engine bay aas some small powered 4cylinders do in older cars eg, cordia, et.....but in the later model cars such as silvias 180s skylines etc they have been placed in a very good position behind and its postion does let in a lot of air but of course nothing beat front mount
