We put one on my buddies jeep and we noticed the low end kinda went away but the 1500-4000 put you in your seat abit. He runs 35" with lockers and 4.88 gears. We didn't like the low end going away but what can you do. Also we installed the banks header at the same time so that may effect the results too.

Here is another individual report where someone swapped out the intake manifold to the newer style: "I just wanted to tell you guys about the updated '99+ 4.0L Jeep intake manifold I installed with a self-bored-out throttlebody. I felt a slight power loss off the line but once the engine hits around 1,500 rpm, it comes alive and hits the redline much, much faster. Now, since I don't have access to a horsepower dyno I just relied on my "ass-o-meter" and felt a noticeable gain in horsepower. I installed the intake on a '96 XJ 4.0L with a K&N filter and a Flowmaster muffler. I would definitely recommend the upgrade, but I have been asked many times what the actual horsepower gain is and I can only say that another magazine rated the gains at 25 hp."

Bryan C. said:As far as rated HP numbers being low, I agree with that. I recently heard at the local DC training center that the new Dodge Neon SRT4 HP ratings were about 30 HP higher than what DC had published, also mentioned was the new hemi 5.7l.
jack SF said:to answer czb83. the 99 intake bolts up directly to the 91-98 head. but you need the steering pump and belt tensioner out of a 95 or newer jeep. wrangler inake and pump set up works in xj too. i got a whole set up from a 2000 tj.
jack SF said:the 91 and newer dont have an egr port like the pre 91, so you wont pass visual smog.
the throttle body and all sensors are different, but i have seen an adapter for sale that would take care of that.
i am not sure about this one, but i think that the 91 and newer heads are a little different. the intake might not line up axactly with your old head, maybe you could just put on a head from a 91 or newer. double check on this.
it does not seem that its worth doing after all those problems. jack
jack SF said:yes lunghd i was replying to you. you should just get the whole set up from the donor jeep. the pump, bracket, tensioner pulley, hoses and all the bolts. if i remember right than the pump bracket and tensioner bracket are 1 piece. i think it might be possible to reuse your existing pump with a little work but i did not want to waste my time with a pump thats over 10 years old. just get the whole thing from the donor jeep. jack
