The two wires on the top of your intake, one goes from the intake manifold, the other goes into the bottom portion of the airbox. What happens is the line from the manifold feeds a vacuum controlled temperature switch. While the temperature switch is cold and under vacuum, it routes vacuum from the switch into the bottom portion of the airbox where it meets with a diaphram. That diaphram controls a flap, which will either close the "snorkel" that draws air from the fender (cold) so your engine sucks in air from around the exhaust manifold (hot) to heat up the engine faster. Give your car some gas, and the flap will start to open up the cold side of the box and close up the hot side for more power.
Now, taking what I have told you from the above, you will realize that removing the "hot" side of the airbox will be where the power comes from. Now, you can do one of two things; remove the airbox and get the intake you linked (can't look while at work, but I will bet money its a "short ram" isn't it?), or you can save yourself some money by putting in a K&N panel filter, remove the vacuum controlled switch, block off the "hot" inlet, and somehow find a way to get cold air from the fender into your airbox. Most common method is to drill several holes on the fender side. Other ways of doing it is taking large ducting or several smaller ducting and attaching them inside the box and route down into the fender, or cutting a gigantic section out of the fender side of the box.
