Actually what you want is cooler, PRESSURIZED air....when you get cooler air from a point at the front of the car with the highest pressure is when you get the most benefits. you want the air in the intake path to be above atmospheric pressure. tape a pressure switch to various points in front of your car, then hook a buzzer up to it so when the switch kick on it activates the buzzer so you know, drive at moderate speeds and the point at which the sensor kicked in at the lowest speed is where you want your intake path to be....this WILL add power, not just lower IAT

This is the best article ever, when explaining how to make a REAL intake

Your theory is correct, but your method is very strange.

Best bet is to use a magnehelic gauge. You can make your own with a U shaped tube of coloured water. Connect one end of the tube to another long tube which leads to the area of the front of the car you are testing. The other end is open to the atmosphere. Or buy one in dial indicator form. They're cheap.

Keep in mind that you will generate very little pressure, so the change in the gauge will be very small. It's going to require several hundred MPH to make 1 PSI of pressure.

Normally AutoSpeed is very good, but that buzzer method is a terrible way to figure this out.

Your method- admittedly viable- is no different than the one I used.
Given that a hole needs to be drilled in either case, it's simply a question of where the hole needs to be.
In the event that you already have an aftermarket filler panel in front of the radiator, there's plenty of space for a cone filter in front of the radiator and you have adequate watershielding for daily driving.
Access is through the top of the engine bay as well, which I consider a bonus.

YEA!!! Aaron Cake agreed with me....I feel kinda smart now. hehe, I never tried the pressure experiment before but am dying to on my TII....anybody care to take on this task

Keeps your engine from rocking while under hard acceleration
