+1 on the filter already being in there. The torque box has the panel filter in it already so another filter on the end would screw that up wouldnt it? Ive seen the Ganzflow intake for sale on here recently. Its basically a pipe that comes off the stock torque box and goes into the fender like a CAI. Supposed to be the best way to get colder air in there, flow better than the snorkus, and still maintain torque.Read up on "hybrid intakes" here:
Also, isn't the filter already in the torque box there? I've seen some people just run a pipe down to the fender wall without a filter on the end because the filter is actually in that box.
