I'm not running a CAI on my car, but I am running the March Ram Air setup, which is essentially the same thing as VW Dave describes. I have a little scoop under the front valence, with some flexible duct like big diameter dryer vent hose going to the air box located where the stock flat panel air box was. The box houses the cone filter, and I've got an aluminum elbow between the MAF and throttle body to replace the stock rubber piece and all its associated turbulence... I think March might've made a setup like this for the 94-95 5.0s too, but I'm not sure. I've heard a few folks mention they wished this was available for a S197. I don't know if it helps much, but I can't see how it isn't feeding some cooler-than-underhood air to the engine.
