You dont have to lift your jeep at all. I have 31's procomp mt's with no lift and i didnt even have to adjust my steering stops. I even have friends that have run 32's without a lift. You will have no problems with the 31's
i put on both the throttle body spacer and cold air on my o4 4.0 and with both noticed a significant differance in performance and slight mpg but if you dont like alot of noise i wouldnt do it
maybe i just like the sound and think its performing better? but for only 225.00 i like it!
You can fit 31's stock, but a 2"BB will give it a more aggressive look. Also, if you go for the lift first, you can go right for a set of 32's. They're not that much more expensive than 31's. You might have some rubbing at full turn.

well the intakes are not exactly a mod to give you alot of power. they just help other mods work better. most of them cost like 250 so they are not that expensive. unless you get one of those 450 jobs you see sometimes. look at it like this, what is the point in say a throttle body spacer and a big bore throttle body if they are still sucking air through that tiny little factory snorkel? their main advantage is what some others have already mentioned, fuel economy, they do help a bit. but the reason i didnt get a cold air kit, especially with the cone filter setup is water. you drive a jeep, if you do not encounter water somewhere something is wrong, lol. i know they are oiled but that will not keep water out. i have seen many cars with cai's stall out just from running through puddles that were too deap. so i went and got the k&n filter for my stock air box, and plan to add a snorkel. thats just my take on it anyway
