They generally follow the windshield so they don't get in your line of sight.

 

i made one in a 85 4runner, ran the tube under the hood, and out the driver side fender, but up the line of the windsheild frame, along the top of the door, and had the intake poking in behind my head (top off) it worked pretty good for a while, then i blew the motor. then i bought a jeep, and haven't looked back


the one on that frontier looks pretty sweet
