Just run a flexible intake hose to the driver side bumper vent (oval one next to the turn signal) and run the hose to your heat shield (if you're using a cone filter) or airbox.

The bumper vent is the best ram air location, right smack at the front of the car. IMHO, it's not worth the effort as you'll only benefit from it at speed and at WOT which only accounts for a small percentage of normal everyday driving.
