Ram-Air, has become a marketing term.
At one time it infered that the opening for the intake tract was large enough, and was unobstructive enough, that at speed, it would serve to force air into the engine.
But, it's fallen to include hoses, and ducting that has so much wall surface area, the it's more a restricton then an aid.
Lots of cold air kits do the same thing, ie add restriction to they system, and their net effect is actually just making the engine a little richer, or making the AE artificially rich. With all the tubing running close to the radiator it winds up soaking up heat.
