Noob Air Filter Change

I have a 1991 Grand Am and I would like to change the air filter. How do you open the air filter cover?
Thanks for putting up with a noob!

Changing the filter is pretty easy. There are 4 screws around the box that you need to loosen and thats all...the screws should be attached to the top part of the box so you shouldnt have to worry about losing them. After you get the top off the filter will lift right out and you can simply drop a new one in its place and put the cover on and tighten the screws and youre set.
