aFe CAI....4mpg gain??

So....I know everyone rolls their eyes over CAI's on here including me because I had one on my 08 and it did very little except sound cool. Anyway, I was in a 4wheel parts store today and asked about the aFe's on the 2012's & 13's and the guy said he and his buddies run them on the 3.6 and they blow K&N away (they sold K&N too so it wasn't like he was pushing his product), and that they've been getting about a 4MPG gain with them and a 12hp/14tq gain which I found very hard to believe. Anyone on here with firsthand experience with these and what have you seen???

If you want one just buy one! This will just be the same thread we've seen a hundred times before! People will always try to justify their purchase. I get enough cold air in the winter here, doesn't seem to help the engine at all haha...

I recommend Banks Ram Air Intake. It kicks ***.

I agree with Pentastarguy, do you really think they would have passed on almost a 25% increase in fuel economy?

If true, Chrysler should fire every automotive engineer they employ for incompetence.

Until I see real scientific testing that conclusively proves the marketing claims, I don't believe them. I have seen too much bench racing in my day.

Either that or email Chrysler and tell them they're doing it all wrong.

I have one, it helped top end for interstate travel but otherwise is not worth anything. I'll be removing mine when the time comes and returning to a modified stock box and a snorkel

As stayed chrysler would have done this. Every thing that comes on a factory vehicle is better. Better in the sense that its made to run as is with optimal performance. It's tuned to run the way it is. Intake, fuel ignition, exhaust etc... When you start upgrading or changing stuff it usually has limitless impact or a negative impact because a link in the chain is changed out.

To get better performance you'd need better fuel ignition system. High flow headers, cats and exhaust and run a high octane fuel that your engine will use up. Not burn up. If you plan on wheeling your jeep all you're doing is increasing the hole and volume in which water can enter. If you take a good look at the factory air box it's actually well designed. Not optimal for high performance but optimal for the overall setup and performance of what the vehicle is.

In order to get all you can out of it you need to change way more than just a intake. That's like adding an exhaust. I'm not against it. I've added exhaust to all my vehicles and its purely for noise. Only cat backs and I know it didn't add HP or torque. Although some people think it does.

If you want more practical air intake and have it look cool with a bit more practicality get a snorkel. It Sits high and away from engine bay. The front of a jeep isn't really designed to force air into an intake. A snorkel would force it a little more. But don't expect better MPG or HP.

I am not a lover or hater of cai set up but I did run one for awhile on my jk and it did give a noticeable boost in mpg. That being said Chrysler would not put one on from factory for the added noise it makes. I liked the noise but the majority of the public would be turned off. It is amazing what the factory does to decrease noise in vehicles, even at the expense of overall design. Ride, comfort, and noise are more important than mpg to the public. I have been a professional tech for 15 years and I know there are more a/c, ride, and noise complaints than mpg complaints. The few that do complain of mpg only do it when gas takes a big hike.

Well, I gave you a simple answer, sorry if that offended you. Cold air intakes are a total love/hate thing. I don't buy the idea, but if you do go for it. As said before if they were that much of a boost Chrysler would have put one in, I'm sure they could probably even make a quiet one if they wanted to.

Actually Chrysler sells one. Has Mopar right on it. I just googled it. They can't put it on from the factory because it's too noisy.

AirRaid sells a "sock" to put on their filter to help keep water and mud off.

I've had good luck with the cai I have on my Ram Hemi. The dealership put it on for me. I think it makes a little more hp in the middle of the rpm range, but not much on top. I honestly think I picked up aprox 1 mpg on the highway. The 4 mpg increase claim, seems like a bit much. It looks kind of cool. Sounds really cool. It was worth the $295.

I won't be putting one on the Jeep any time soon, tho. That 3.6 makes more than enough power. Factory stock and warranted is more important in this application.

Buy one and report back.
