Air filter question

I have an 02 pontiac grand prix gt and i bought a k&n replacement filter. I got it the other day and looked at the instructions. It told me i had to unhook three things or so before undoing the clips to put the new filter in. Is this necessary? Because I'm not too car savvy and i cant find these three parts.

Thanks in advance by the way guys

As long as she doesn't throw a code your probably good.

The instructions are your friends , especially if you're not very " car-savvy " !
