It will work on a 98. I just picked up an intake manifold off of a 99 grand for my 98 4.0. I also picked up the Banks look-a-like, and I'm gonna do em both at the same time. You only need new power steering stuff on the pre 97. I picked up my manifold, complete with fuel rail, injectors, and throttle body from a local junkyard for $125. That seems to be about average, unless you can get it from a u-pull-it yard. I'm keeping my 98 injectors and TB, and I'm gonna throw the rest on ebay.
