Here's the logic; in 99 to meet stricter emissions the 4.0 dropped to 177hp, same as remix, to get that make the chrysler engineers focused on the intake and when finished ended back up at 193hp and 235tq, installing the intake on 4.0 with the less strict emissions will get you the difference, about 13hp and 10tq.

Your MPGs will suffer a bit for the first tank full of gas because you're gonna play. Normal.

Also do not get a throttle body there are countless people on here saying they're pointless. With one and the bored throttle body you're going to get a loud whistle when accelerating that is going to turn every ricers head.
