I think we can clearly stop using the term "ram air". The physics behind it prove that there is no such thing on a vehicle going the speeds we typically travel.
However, I believe the confusion stems from the fact that these "ram air" style kits such as the OTR intakes do (in most cases) improve the flow of air and are able to get colder air to the engine, therefore increasing horsepower and leading people to believe they are obtaining this ram air effect.
This is as best as I understand it from reading all posts up to now. If this is correct, I hope we can all stop arguing. If not, I give up
