Put together a Ram Air/Freash Air intake on my '91 GSX for about $15 using the stock SMIC ducting (I no longer have the stock side mount IC) some dryer ducting, scrap ploycarb sheet, and some fabrication.
I carefully cut the polycarb sheet to fit the back of the stock duct so the round dryer duct would fit it. Routed it up into a hole I cut under the MAF air filter, where the original IC piping was, and attached the dryer ducting. A little spray paint prettied it up a bit and blended it in a little.
While technically not "Ram Air" because it's not sealed to the MAF, it does provide for a constant flow of fresh cool air while moving. It should also provide a slightly positive pressure to displace any hot under-hood air around the filter.
