I know that the stratmosphere hyperflow induction is a good product, but what other intakes are good for the S4?

None until we get TRUE CAI.

CAI is only good for sucking water.

transfer and is a true CAI. It is not a ram air system. The only true street legal ram air systems that actually worked were the Ford "Shaker: scoops that were connected directly to the carburetor. Any tubing other than a straight, short shot into the intake has inherent backpressure that actually inhibits air flow. Getting high pressure air into the engine through a scoop is not an easy proposition. Most outside air flows by the scoop. If you want a CAI that works for your Audi remove a headlight and pipe a conical intake to that, of course that is not street legal and astethics are a bit rough. If you look at the pro stockers those barns that they build on the hoods are true RAM/CAI systems but they are not very aerodynamic. Pure brute hp overcomes the drag that they create.
