I have a 97 GT and the horrible intake manifold it came with and had the intake replaced by ford around 2000-01. I was just wondering if anybody knows which manifold was put in its place, a revised pre-pi version or the pi-intake? or if nobody knows, could someone describe the difference, (visually), of the 96-98 manifolds and the 99 up PI version. i'm lookin to do the pi intake converison if i dont have it, anyone know where i can get those adapter plates?(besides livernois) thanks to all.
