All you need is a hole saw and some door seal from a junkyard.

1. Remove the airbox lid and make sure your hole saw will fit in the circle PVO gave you on the underside of the airbox lid.
2. Drill the pilot hole in the center (but not the whole hole), then place a screw or something thru it and let the screw stick up about 1/4". Replace the airbox lid. Take some white out or something and paint the top of the screw, then close the hood.
3. Open the hood back up. You should have left a mark on the hood. This is your center for the hole in the hood.
4. Remove the airbox lid again, and drill the hole thru it. Use a razor or something to smooth the edges, then replace the air box lid.
5. Cover the engine bay with a blanket or a large piece of cardboard. This will prevent the metal shavings from the hood from getting into your engine bay.
6. Tape a 1/8" drill bit with duct tape, leaving only about 1/8" exposed at the top. This will allow you to drill into the hood without the bit pulling itself thru and damaging the top of the hood. Drill where your mark was placed.
7. Now, take your hole saw, and remove the pilot drill. Again, tape the drill bit and enlarge your pilot hole in the hood.
8. Place the pilot drill back into the hole cutter, but place it in backwords. The bottom of this bit will be your guide for the hole cutter, but you won't have to worry about cutting the top of your hood.
9. Place some masking tape around where your hole saw will cut, this will prevent you from chipping the paint.
10. Slowly, and very carefully, use the hole saw to cut into the hood. Let the saw do the work, and take your time. You have between 1/4" and 1" of clearence on the other side of the hole, but you do not want to damage the top of the hood.
11. After you've made the hole, take a metal file and file the edges, so you don't cut yourself.
12. Place the weatherstripping around the hole in the hood. You need about a 9" section, and it is a pain to get it around. I had a whole section of stripping from a door, so I was able to cut sections a couple of times to get the right length.
And thats it! You may want to keep some plastic wrap or something to seal the top of the airbox when you wash your car, or in heavy rain. Under normal circumstances, or in normal rain, the water shouldn't get to the filter. While this mod isn't going to increase your horsepower by a ton, it will reduce inlet depression. The junkyard gave me the stripping for free (i'm a regular), but it shouldn't cost you more than a few bucks. The whole ordeal only took about 45 mins.
