Does it Work?

I think it works great. Of course, without a dyno test I don't know for sure. It is hard to judge the difference because it SOUNDS much faster. You can hear the air intake now. Some people call this the CAI "Roar." It is a noticeable but pleasant sound.

FINAL THOUGHTS.

Do it yourself is not for everyone. If you are uncomfortable with the process there are plenty of CAIs that you can buy. Also, there could be new car warranty issues. I plan on putting my old stock airbox on (yuck) if I need to take the car in for service.
