Intake manifold swap. 97 to 99. Missing something?
I have a 97 ZJ with a 4.0 I6. I have gathered on here that swapping the intake manifold from a 99 WJ 4.0 will give me a good upgrade in power. I have read most of the searchable threads, but still have one remaining question:
It looks as if it is a straight swap, but before I dive in, IS IT? Are there any modifications I need to make to the new one? Is it as simple as a 'remove/replace' as all the threads make it seem? I just want to be sure.
I don't want to tear apart the top part of my engine just to find out I forgot something stupidly obvious. Any advice from someone who has done this would be greatly appreciated.
I am hoping that swapping intake, and adding cold air, and a header back exhaust will really boost me up power wise.
