I'm gonna put a air box in my CJ. I got a XJ box for dirt cheap but the mounting base is awkward in a CJ. Is a YJ box a lot different at the mounting base? Hopefully so to make an easier fit, I'm already have very little space in my enigine compartment. Thx in adv. Doug

I already have a SMPI. So, the question is still up, is there a difference between YJ and XJ air boxes?

Now I read your last line, the boxes are the same, ok, I got some cutting to do. Thanks for the info.

Little know fact!!!!
if you look at the HP rating on the XJ and rhe YJ they are different but have the same motor. "What gives?" you ask. If you look inside the air tube right off of the YJ air box, it has a air restrictor in side it. All you have to do is pry it out and you get the same HP as the XJ.

air restrictor? forget that wimpy 2.5" intake entirely and upgrade to 3", mine works great. I can use 5th gear since changing and have a wider powerband.
