Is it worth it to cut the air box lid? What kind of gains do you get from it? Any Horsepower? Better Airflow? What should I use to do this with, and how much should I cut off? Thanks, Zak.
Cut it around the outer edge, be sure to leave enough to hold the filter in place. Use a K+N filter and remove the screens from your MAF and you should feel a small difference.
You can use a cut off wheel if you have a grinder. Or go with a jig saw with a metal blade (will be a little rough, but use a file to smooth things out). You get better air flow at WOT. You will not notice a large difference. But you can hear a difference if you are outside the car.

Have Fun, Paul
I would pass on cutting the MAF Screen. This was a big debate about a year ago, most of us agreeing that there were no real noticable gains, and in some cases (like me) a performance decrease. The screen does not limit air but does effect how the air flows through the MAF. As for the lid....
I just cut along the louvres with a hacksaw. No need to get any larger than that. There is plenty gap between the lid and the filter media to accommodate. Using a K&N will help as well.

opt for this practice on a spare lid purchased from a junkyard.
because you'll soon find all that will happen is your air filter will get a ton dirtier, all the while you'll feel no improvement at all......so you'll be removing it in favor of your original stock lid.
