99+intake manifold swap
I have a 98 xj, and I reciently found a local guy that was parting a 99+ motor and is willing to sell the manifold to me for $25! How could I say no? My question is how do I install it? This is my first engine mod, and would like to get it right the first time. After searching briefly, I was unable to find any tutorials. In addition to the manifold itself, do I need anything else? I have seen things about brackets and injectors...ect, or are those for older models? As I mentioned above, this is going on a 98 motor.
Thanks in advance guys!

Nothing on this?!
I dug around and found these links on other forums, but nothing is very specific. I am guessing since I have a 98 that I am not going to need to worry about buying new brackets. I just might have to extend some vaccume lines. Other than that, it seems to be pretty much a bolt on type deal.

The only real question now, is should I use the injectors off the 99+ IM, or should I just use the existing ones I have now and mayber replace the o-rings on them?

I am in the process of this same mod on my 98 zj. the 96-98 injectors have a higher poundage than the 99-01 so stick with your originals

So I just got my 99+ intake back from my friend that sand blasted it...looks newer then new. I was showing it to another Jeep owner that tells me "That thing won't give you any power...you just wasted time and money." He sites an article in a recent JP magazine, an article I cannot find. Reportedly they dyno tested common "power myths" and found this intake to be a non-gain. Anyone know what he is talking about? Anyone agree? Anyone who has done it have any comment?

lol what? Forced induction "false"? Did you just say that a supercharger or turbocharger will not make more power? I need to get a copy of this months JP mag and see for myself.
My Jeep has a high flow exhaust and I plan on boring the T/B if I do the intake. As for a cold air, I'm worried about dirt and such so I am going to do a tractor air canister and a cowl induction.

high quality cold air like k and n airid etc have a filter just as good as a factory flat filter so should be ok you can also get the foam wraps that cover the filters for better filtration good luck.

I am running the 99 on my 97, I also have a jeeperscreepers TB, I believe its 60mm and borla header. I can say it seems to be a power increase But I still havent regeared the diff. yet. still have 3.73. I think when I get 4.11 gears I will definitely feel it in the a$$ometer.
