I like everyone else that own a 4.0 Cherokee has heard that if you put a 2000 or newer intake on your ride that you can get 25+ extra HP, blah, blah, blah. I have never talked to anyone that has done it, so has anyone done it and did it help? Just wondering?

What part of the intake? Throttle body and everything? The newer 4.0's user different sensors in the tb and manifold that are controlled a little different than the Renix 4.0L's that your 89 has, but I'm no expert on this.

Where did you hear this? I actually have an 89 and a 97 I could compare.

I would just make it work

I was thinking on using the orig TB and just drill, tap and plug stuff to make it work. I would even use the 1989 fuel injectors and possibily fuel rail (if it bolts up). I know a newer TB would flow better but one GREMLIN (I'm funny huh?) at a time is all I need to sort out. My Jeep is my daily driver and I'm building a Scout so when my Scout is a little more reliable I'll think about trying it out if no one else has. I'd dyno it before and after but I'm kind of cheap.
