So I recently got a jeep grand cherokee with the 5.7 Eagle Hemi. I know the gen 4 is basically the 3 with upgraded higher flowing heads. Does this mean all the gen 3 performance parts still bolt right in? Looking to potentially cam/ add an intake manifold in the future but all the parts I find always say gen 3. Sorry if this is a stupid question just haven't had luck searching.
