I just recently purchased a 2008 Jeep Wrangler Unlimited Sahara, and I was wondering if it's worth adding a Cold Air Intake kit? Does it actually increase your HP & Fuel Mileage?

It's generally known that CAI's provide little if any increase in power or MPG's. They do provide noise increase though! Save your hard earned dollars for something else.

Just one perspective; for me, the intake system wasn't for a HP or MPG gain, but more to loosen the girdle around the engine. A good intake will increase volumetric efficiency and make throttle response quicker and make the engine "spool up" more smoothly. That being said, I doubt as others have indicated, that you will see any appreciable gains in HP or MPG. :)

How come adding a cold air intake and free flowing exhaust gives better mpg and hp, tourqe and all over better performance on just about every other car or truck but not on a Wrangler ?

The thing people continually miss or overlook is this:

The stock intake is restrictive...that's true. However, it is most restrictive over 4500 rpm. Furthermore, in the intake manifold is the most restrictive part.

Don't believe me? Look at the torque/power curves for the Pentastar in the Wrangler and then in the Challenger. That's a 20 hp difference, almost all of it up top...and what's different on the two vehicles...I bet you can guess at this point.

Your intake is only as good as your most restrictive component. Besides that, Jeep stuck us with a V-6 instead of an I-6...so its natural tendency is going to be to make the power up high. If I could gain an additional 20 hp from 4500+ rpm I'm not even sure I'd bother to be honest...it's not like I'm tracking my Jeep.

However...people do it because they want to and it makes them happy. That's the beauty of it...make your own choice with your money, good to go. At least in my eyes, trying to improve your Jeep's performance where it spends most of its life is a hell of a lot more valid than going for a "more aggressive stance" (which makes me want to kick babies every time I read it).

I appreciate the link that you sent. This was a very informative thread. After reading through the threads, I've decided to go ahead and replace the CAI.

I find it interesting that it's cool to drop $1,500 on wheels and tires, or bumpers, or fancy audio systems, or whatever else your heart desires and talk about it on the forums. Things which do nothing but destroy fuel economy and wallets. But if somebody drops $275 on an intake kit they get told that they just threw money into the wind. Hilarious..

I would not get rid of my Airaid kit. It sounds a million times better, made the throttle noticeably more linear, and requires no more air filter purchases. And, every 10 ft/lbs of torque is worth it. It makes me happy...and isn't that the point of ANY modification?

Got my vote. I don't know why but for some reason, most on this forum hate CAI units. I plan on going the Air Raid route as well next summer. To each his own i guess. :thumb:

I noticed an increase in acceleration and throttle response the second I installed mine.

I got wheels AND tires for $1478 shipped. Yep, all 5.

To stay on track, I have installed a K&N, and uninstalled a K&N because there was no difference on my rig, and my understanding is that the K&N will let more dirt into the engine. It just wasn't worth it to me. :nonono:
