The sensor is called an Air Intake Temperature Sensor. You need that in the piping otherwise you will get a Check Engine light. The AEM clone is rather cheap and it is a great setup.

The place javageek is talking about is this.

-Take off your Left front tire.
-On the left (So parallel to the front bumper now) There is a plastic mud guard. It goes above there, it is almost in the front bumper. You also have to cut a piece of plastic to make the intake fit. about 3 inch by 3 inch or so. You'll see if you buy it, but it is the best one.

 

dang dtn you didnt listen to your own advise. now redz will have you a$$ lol
bk on topic, get an aem all holes are pre drilled and it does show support for one of our very few aftermarket supporters.
