sorry about that i am wondering looking at teh pictures of these aluminum air boxes that have no lip to attach the air filter onto do they have them or not and if they don't can i use a pro deisgn pro flow kit with it?

 

Most of the time they are made to use a specific k&n filter (clamp on type just like the pro design) and you usually just can't see the lip in the pictures from it being an isometric view.
