OK Here goes. I'm going to assume you know nothing about the airbox at all, including how to remove it from the car. Also, this mod is very mild. Besides removing the baffles, I did not cut a huge amount from the front of the box for additional air. Many members cut more out in the front, and some run tubes down behind the headlite etc. The tools you'll need are a 1/4 socket, a standard (blade) screwdriver, something to cut the box and sheetmetal with (I used a dremel with a cut-off disc). I also used some weatherstripping that you can buy at Home Depot or other place that carries such stuff. My intention was that anyone opening my hood could not tell that I gutted the airbox. Here we go with the pics. Most included text within the photo as an explanation.
Remove the airbox.
I like to unplug AIT sensor also. It is that small connector on the accordian duct. Unhook the accordian duct after you have loosened the clamp
Don't try and remove this thingy like I did. It is just a grommet post! Just pull up on the box.
This is what the front part of the box with the baffle in will look like:
This is what the rear part will look like with the baffle in:
Drill or grind off the tabs that have been melted to hold the baffles in. Below are the baffles and the two box parts with the baffles removed. In the pic of the front baffle removed, I have already cut the oblong hole where the smaller circular hole was initially.
This shows the new hole from the front of the baffle:
With the weatherstripping on the front.
This is the stripping I used:
After you cut the opening in the front of the box, put it back in the car look where the box meets the sheetmetal under the radiator support. Use something like a Sharpie pen to reach in and outline the sheet metal to show where you need to cut.
Enlarge the opening behind the headlight and in front of the airbox. Put stripping around it. Don't cut any wires accidently. Unplug them and move out of the way.
You're pretty much done. Get a compatible high-flow filter and drop it in where your old one was. K&N and Amsoil make good ones. Check the internet for the appropriate model for your car. Put the box back in and off you go.
