it's a 98 XJ with the 4.0.
I know one of them is a PCV valve, is the other one the same? And does the front one need vacuum, or just filtered air? I have an empty vacuum nipple tapped into my intake manifold, can I just hook the line that used to go to the airbox up to the empty nipple?
Also how do I clean them?
