If you want to keep your stock airbox but want more air, may want to consider running a short 1 3/4 inch diameter piece of flexable hose from the bottom of the black fenderwell boot to the bottom (near the opening) of the conical air box. I was thinking about this plan before going the KKM /custom airbox route. Previously I ran 2 long 1 3/4 inch pipes from the front airdam into the lower portions of the stock airbox. Seemed to get more air in as evidenced by a 1-2 MPG increase in fuel economy, same as with my KKM. But if I were to do it over again, I think I would do the way I suggested above. This will of course slightly mutilate your airbox so think carefully.
BTW, Brad is currently "smoothing out" a throttle body for me. I'll post feedback when its on.
