Hey guys Im new here. My 96 stang aint the fastest around and Ive been slowly moding it up. Anyway next in line is the intake manifold. I here a lot of people switching to the 99 PI manifold. I was wondering what all I need and what is involved and what I could expect as far a performance gains. I already have the rest of the induction done and this is next in line. By the way I havent done the recall its all plastic. Any help will be greatly appreciated. Thanks!
