well when your moving the filter being higher or lower wont matter, just that its getting air from outside and not from in the engine bay. Thats the part you dont want. But even If you do get the filter outside, There probably will be no noticaeable gain. The restriction from the tube still adds up. Even if the tube is straight, Because its friction is a coefficent of length. But screw sicence, just do whatever floats your boat and looks cool i guess lol.
