would anyone know if you could take an ram air box from the new gen firebirds and use it in an third gen car? would there be any mod's too make it fit? Our would i have to make an custom Air Box? If so Anyone know where i can find one?

call Suncoast Creations they make a Ram Air box that fits on thirdgens

Whether it actually fits will be another story.

Try ramairbox.com they make a pretty good looking one.

yes the suncoast box fits I have one under my ASCD hood I did have to mod the hood though.
