Snorkel or make a cowl intake.

Any "cold air intake" that's still in the engine bay is actually just sucking up warm air.

This ? Seems to come up weekly. The stock box was designed for these Jeeps and for a daily driver I wouldn't spend the $$.

Useless unless you have the other mods to go with it, and a snorkel is money down the drain without a ton more work done.

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?

This is the best cold air system and it was only about 30 bucks for the hat and tubing. http://www.jeepforum.com/forum/f13/d...5-9-a-1315001/

And it still filters dirt unlike the K&N. I would wait before you waste 300 bucks if you are unsure what to do. There are many better things you could put that money too other than a K&N.

Don't bother with one. Not with the cost.

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.

By the way, that picture is a 5.2L and your profile says you have a 4.0L

Kanerbo is right, that is terrible placement for the cone.

Have you upgraded your ignition system already?

Champion copper plugs
Brass tipped distributor cap
New cap/rotor

The stock wires are 7mm I put a set of 8mm on mine.

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.
