Down side:
Technically, they should let more dust in, especially when not using a pre-filter.

My experience:
I bought k&n for my mustang and jeep, threw them both out after 2 weeks of dealing with MAF sensor problems. I didn't even oil them, since they come pre-oiled. I bought the AEM dry filter and have run it for 12 years now (140k miles), no problems, and no dust in the intake.

Again, no performance gains, but I am not seeing any drawbacks either. But there will be MANY who disagree with me.

SurfKaster Buy a winch. It'd look cooler & you get better power gains.

krisbman I built my own. Would i buy one... Nah. And yeah 10% is a big gain, doubtful you would see the extra 20hp. Not trying to stray here but the whole percentage thing is really kind of a misleading thing, for instance... My boss just had a 468 big block chevy built for the shop truck ( fully custom hand fabbed 68 chev) all roller cam, AFR heads, scat crank yada yada. Engine builder says easy 625hp. We do several dyno pulls with it with a dual plane intake and a vacuum secondary( choke wheez) carb. Best number... 540hp. Nothing to sneeze at grant you. My input was go for the single plane intake and a mechanical secondary. Dyno guy says, no way those are a pita and will only net 10-20%. So i split the difference. Were all smart here, do the math. Sorry for the rant. Do what u want man. Its yer$$$ and yer jeep. Even if you only see 3hp and 1mpg it will pay for itself in a a few tanks of fuel.

They advertise 20% increased HP, which is a very optimistic number if you ask me, considering that is near 40 HP, but from what I have read, people have noticed 10%+, which is still around 20 HP. I'm not sure why people assume that we want more HP for "1/4 mile times"; i just want more HP to turn my 35s, to reduce the number of downshifts, and to increase fuel efficiency.
20%? You won't get 20% without spending at least 3 grand unless you go nitrous.

How do you "notice" 10%. Butt dynos are not that accurate and dyno sheets are notoriously manipulated.

If you spend a lot of time in dirty/dusty conditions I can see a CAI not being all that great for the engine. The best way to find out is by doing a before and after used oil analysis. You may find that you need a pre-filter wrapped around the cone filter...defeats the purpose if you ask me. If you have never done it before you can request a free test kit here Blackstone Labs .

I understand the attraction in MPG increases but how much can these kits really do without further upgrades like those listed above? If you want more power, supercharge it. Want a great all around vehicle that can accelerate like stock? Regear it to proper gearing. If someone has this kit, could they please post some dyno runs with and without it? Thanks.

Sortof. He says he knows it, but he doesn't really know it and he's hoping someone will give him a reason or a glimmer of hope that he was mistaken.

His parents probably never let him stick his hand in the fire to know it will in fact, actually burn you. They just told him it would and protected him from knowledge.

SuicideSaints I have a weird opinion in them. I have the airade (however it is spelled), a TBS and flow master exhaust. This all came on my jeep when I bought it. Do I like all this stuff? Yes I love the look and sound, but would I buy all this if my jeep didn't come with it? Probably not. Am i going to take all this stuff off? hell no!!!! I would go functional mods first, lift ( done right), tires, bumpers, lockers, winch. Ultimately it is your jeep, do what makes you happy. Do what you like cause it is your jeep not anyone else's.
05-17-2013 10:52 AM
Dextreme I love my AirRaid...On my 5.9 Cummins. But on a Jeep where you are more prone to get water splashing up on the engine, having a wet soggy CAI filter kills engine performance and may not even run until it drys out. The stock airbox is designed to keep the splashes out. Stick with the OEM air box!
05-17-2013 10:33 AM
Jerry Bransford In my personal opinion, there is nothing about a CAI when installed onto a Wrangler TJ engine that is going to help improve performance, HP, or mpg. Despite the marketing hype that makes all that seem so plausible to some folks.

And those .5 to 1 mpg increases some think they're getting with each mod is just not going to happen. Think about it... the EPA/Feds are ALL OVER the automotive manufacturers to improve their fleet CAFE mpg averages. Jeep extracted every last possible mpg out of the 4.0L and 2.5L engines they could before they were forced to abandon them and install the newer technology engines where better mpg was possible. If it were only as easy to get .5 to 1 mpg with each minor bolt-on modification, they would have jumped at them. Don't fall for the glib marketing hype.
05-17-2013 09:16 AM
CheepJeep2001 Can't say I noticed anymore power. But my milage defiantly improved. Not by lots but if you gain 1/2- 1 mpg with every mod then by the time your done 6-7 mpgs makes a by difference. CAI are one of those things that helps out other mods. The more you do to you jeep the more it gains. And if your looking for mpgs don't underestimate a fluid change, grease gun and clean air filter. You'd be surprised.
05-17-2013 08:56 AM
MFsoftball22 I have the Superchips Trail Jammer Package, which includes the CAI, Throttle Body and Programmer. Honestly the only thing that i noticed is a slightly better throttle response. Thats it! it looks good and sounds cool but there were better things i could have spent my money on, but the great thing is its my money and i can spend it how i want.

I stay away from Ebay stuff but again its your money.

joeinajeep I've never understood the assertion that an upgraded exhaust could help an upgraded intake...
05-17-2013 07:38 AM
O_M_Jeep A CAI is like a motor mount lift, on it's own it doesn't do you much good, on my 2.5 I noticed a little more responsiveness in the "butt dyno", but certainly no other increases. If you want to have a CAI that's effective (and it's still going to be argueable how much better it is) then you will need to also look at upgrades in your exhaust and ECU programming.

As for why the CAI calls to you OP, that's easy, they look cool, and if anyone here is going to give you crap about doing something because it looks cool, well, Mr.Kettle, meet Mr.Pot lmao.

It's your Jeep, do what makes you happy.

I agree. Plus some of them look pretty nice under the hood.

joeinajeep On a stock motor, you could easily spend over $1200 on a CAI, throttle body spacer, larger throttle body, and full exhaust system, and still not notice significant gains.

The computer controls the air/fuel mixture, and the stock intake provides more than enough volume as is. Similarly, a 'free flowing' exhaust doesn't change (much) of how fast exhaust gasses are pushed out by the pistons.

Now, for the same money, you could install a new camshaft and chip, while keeping the stock intake/exhaust, and notice larger gains.

That said, I myself have a custom intake with an AEM filter (to make room for my York compressor and truck horn). And I have a straight piped exhaust with a glasspack, because I like the sound.
05-17-2013 05:29 AM
BigCrave The most significant gains are made in the 4000-5000 rpm range. Who wants to run their jeep at those kind of rpm's?
05-17-2013 05:12 AM
pyrilampes This is the best article I have found on this. Makes sense to look at the after cat systems first. http://www.jpmagazine.com/techarticl...ing_true_lies/
05-17-2013 02:41 AM
tweeds2 I think there not worth the money for a slight increase in power and MPGs, the stock intake can flow much more than that 4.0 needs and it's very high off the ground right where all your other breather tubes are, invest your hard earned money in other, more useful mods, just my $.02
05-17-2013 01:39 AM
kdilly I like my CAI solely for the purpose of raising the air intake above the hoodline. Its great for the moments when something ends up being deeper than you think it is. Also, it looks much better than a snorkel and doesnt depreciate the value by cutting holes in the body. I think if I bought a jeep without one, a CAI would be my first upgrade hands down. Especially since it doesnt break the bank

Waste of money. No improvements. You can read all about how they don't help.
Better flowing exhaust will help more than the other gimmicks. CAI is fine if you are doing highline fenders and have no room for a stock airbox.
These Jeeps are not performance vehicles no matter how many little mods you throw at them. Now if you had a high performance car then many of these mods will work. The stock intake is a well designed unit that doesn't need any help.

"Look guys I have a cool CAI that does nothing except remove money from my wallet keeping me from adding better mods I could have spent it on"
