DARINTAKE ftw. I did it to mine and it worked very well. Blue_s4 is right about the 01.5 thing, my s4 was an 01.5 and I never had any problems with the k&N even though it was oily. S-flo is ok, but imo not worth the cash. Open elements filters have a tendency to screw something up...at least it did on my friends 00 s4

no, but i can promise you they do not work as well as the forge 007. since its not releasing all the air back into intake, only part, it will make the turbos have to work harder to keep up, and cause a slight drop in effiency. of course if you build your vehicle correctly, im sure itd be fine

This statement isn't quite right. When the throttle plate is closed and the valve is actuated as far as the turbocharger is concerned it is irrelevent if the air is vented to atmosphere or recirculated, either way the compressor will need to re-pressurize the intake tract.
