EDIT: REMEMBER TO RESET YOUR ECU! Some people claim that the idle somehow dropped or is rough. It will go away after about a hundred miles because the ECU needs to adjust to it. If you don't want to drive around like that for a hundred miles, do the ECU reset. This is recommended if you remove both the screens (what most people do).
Resetting procedure can be found HERE

Then you open it, if you look towards the end of the air intake box, you'll notice two flaps. They look like this:

Now, all you have to do is repeat the steps on the other side, close up the box, stuff it back into your car, and done :)
