Just to let you guys know, BAT makes one that comes with the tube. And Technicaly that is not Ram Air, un less the actaull filter itself is enclosed in an air tight seal box.
If you look at a Comaro SS Ram Air system, when the hood closes then it forms a seal around the filters and the only way air can get in is through the Hood scoop. Thus there is no loss of pressuer and you get the full effects of the cooler, high speed air.
As far as I know threre is no true Ram Air conversion has been done. And from the way some of the Veterans of the site talk, its not something that would help very much.
But the system you guys are talking about is still concidred Cold Air.
