Well i was about to order the K&N FIPK for my 5.9 but im hesitant to spend 250$ untill i ask you guys what you think, this forums been extremely helpful! Out of all the intake systems what do you think is going to be the best performance intake??
Keep the intake stock. You could try running a K&N filter for the extra air flow. A throttle body spacer is relatively cheap and would help with air flow as well. Other than that and exhaust/ignition upgrades, the 4.0L does well how it is.
Well ive got 3" exhaust to a magnaflow cat and flowmaster muffler so ive got flow through my exhaust, and i cant keep it stock cause its already got a cone filter from the guy before, but its old and only comes about a foot off the throttle body and catches ALLOT of heat. So i just wanna do a new system, and along with that im also getting a 52mm TB and spacer, so a cold air intake would be an appropriate upgrade i think? Im just wondering if k&n is THE one to get?
haha that is sucking the heat straight from the headers and engine block man if this was my jeep i would go to advance auto right now and just buy some tubing and clamp it. get that cone as far from the engine as possible
I have one and it made a small performance difference, but that still isn't worth it.
It also doesn't seal well against the throttle body with out an additional spacer...after that I feel better about it but I still want to get rid of it and go with the stock box and durango air hat.

buy a stock box and a durango air hat when you go to the salvage yard.
or a ford windstar filter box, durango air hat, and some straight tubing and silicone reducers from autozone to run it to the grille.
knn is a total waste of money when MUCH better options are out there like those listed above.
'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
