Now that the warranty disclaimers have been stated I hope this thread can become a place where people can post there results. This would allow people to start to make informed choices about the different manufactures offerings.

As I posted in another thread:

"I have the afe Momentum dry CAI (I know, I know, not a true cold air intake) and like the sound as well as the feel and increase in gas mileage combined with my afe exhaust and Superchips Flashpaq. I am happy and not concerned if others approve or think I am misguided."

FWIW, the dealer and/or manufacturer can do all they want in an effort to get you to pay for warranty work, but the Magnuson–Moss Warranty Act( Magnuson–Moss Warranty Act - Wikipedia, the free encyclopedia) puts the burden of proof on them to show whatever you did(in this case a different air box) caused the breakdown/problem. It's against federal law for them to deny warranty coverage based on you simply changing out parts without proving what you did caused the problem.
It might take a trip to small claims court, but it IS the law.
Lastly, I used to run a motorcycle road racing team out of my small Kawasaki dealership, and I did a significant amount of testing( on a chassis dyno) to find out just exactly how much hot air hurts power, and whether or not any of the aftermarket filters actually added power.
In a nutshell, I found out pretty-much across the board, that when your intake air got above 90deg, you're gonna start losing power. When it got to 100deg you're losing 10%.
I tested 3 of our racebikes, which varied from a 90hp twin, to a 120hp 600cc I4, to a 200hp 100cc I4. I also tested a stock 600cc I4, and they all lost the same amount.
Incidentally, in order to be a REAL 'Cold Air Intake', the air needs to be pulled from OUTSIDE the engine compartment. Not only is the air inside the engine compartment super-heated, it's also full of contaminants. Oil/fuel vapor, dust etc.
Now days stock intakes are pretty well designed, and in addition to providing a hard-to-improve-upon design, they actually do a better job of pulling in 'cold' air than what's offered aftermarket. How an open filter sitting on the end of a snorkel inside the engine compartment can be called 'cold air' is beyond me, but that's what a lot of 'em are.
Either that, or air boxes that don't even seal properly.

I was looking at this exact kit but decided to hold off until I was able to find more information about it for the 3.6L. Thank you for your honest post regarding the quality and performance gains (perceived or otherwise). The filter is what originally attracted me to the kit but I settled on an Airaid drop in dry filter for the OE airbox. Seems to be working just fine versus the stock paper filter.

So, a huge added benefit that I wasn't counting on from my Afe system:

Room in the engine compartment!!!

I have now mounted my Contactor control/Solenoid for my M8000 and the relay for my IPF lights in space that was taken up by the stock airbox. For what I paid for the Afe system I think just the space for the stuff alone was well worth it! Any MPG, performance or sound is gravy!

Update: I am in the middle of a 3000 mile trip and the first time I have had a chance to measure performance (mpg) doing nothing but highway driving. The only problem with I have is I have nothing to compare it to as I have never taken a trip in the winter time. Anyway here are the results so far. Oh, this is all inter mountain driving, Washington, Oregon, Idaho, Utah, Arizona, Nevada and California.

I will break this down into 2 parts. The first part of the trip speeds where 65-70 mph and averaged 17.1 mpg. The second part of the trip is confusing, speeds 75-80 mph. The first tank came in at 13.8. The next 2 tanks were 17.9 and 17.7. I don't understand why the big difference unless I calculated wrong nor do I understand why my mileage was better at 75-80 than at 60-70.

Anyway these are the numbers and I don't no if they are better or worse than stock as I have nothing to compare them to. The trip home is 1100 miles at speeds of 65-75 if I remember correctly and I will post those numbers when I get home.

Not to bring up the warranty issue again, but Chrysler wouldn't warranty my 2009 Grand Cherokee limited when the "Leather" cracked and opened to the padding with 22k miles on the odo. I traded it in for a BMW shortly after and never looked back.. Until I just bought a 2015 wrangler.

All and all, do what you want but expect them to fight you on any warranty issue.

Wow, interesting to see a CAI result in such a drastic improvement in MPG. Considering the JK gets 15 mpg (with good behavior) getting over a MPG in range is pretty substantial. Is the majority of the OPs driving highway?

I have a K&N intake in our JKU. Did two 200 mile trips over the past couple of weeks. First without the K&N and then with the K&N. Without I got 17.3 mpg. With the K&N I got 18.5. YMMV but I'll take it. A little bit of sound and better mpg for about $260 (on sale).

Update: Finally at home, total trip mileage is 3200.On the trip home from LA speeds varied from 55 to 75 mph. Low tank was 16.7 (LA area driving) and high was 17.9. Over all for the trip I drove 3260 miles and used 189.9 gallons of fuel for an average of 17.2 mpg.

As I said before I can't really make any comparison with these numbers. First this is on winter fuel and I have never done a winter time trip. Second the Jeep never seen sustained speeds like this. So this is all new territory for me. I may do this same trip in August so this does setup a comparison later this year.

My first post is all commuting mpg which is only 18 miles round trip and is not highway driving. 12 stop lights in 9 miles.

Very hard to tell. I have been living with high horsepower vehicles for 10 years so you can imagine that the Jeep is underwhelming. Anyway since my trip it does feel like there is some pickup in power. Maybe just that many highway miles cleaned the crap out of the motor. It does seem to pull harder.

I have the Banks Ram Air CAI and I was a little disappointed with the fit and finish. Seems like there should be a rubber grommet between filter housing and intake tube. Grommet for air flow sensor was cheap rubber push through instead of screw down one like factory. No real gains that I can tell, average about 17.5 MPG combined in summer, 15.9 in winter. 3.73 gears, automatic, 315/70R/17 BFG All Terrain T/A KO's with 2.5" AEV Dual sport lift. Hardtop JKU in Michigan

Only you can answer that question. If you are at all concerned about warranty then no, I would not put one on. In my case though the improvement in MPG means it pays for itself in about a year.

Terry we just got back from a Death Valley, CA trip. Towing my wrangler on a trailer with my 05 Tahoe the tow mileage in CA when up 1.5 mpg. Driving my wrangler in Death Valley the mileage went up 2 mpg. I wondered why and found out many gas station in CA are non-ethnoal gasoline.

That would explain it but there are only a handful of stations in CA that are ethanol free and cost was approaching $6 a gallon in December. Now I would believe that you got early summer blend full as the switch starts in March.

I have a ethanol free station 2 miles from me. I think I will run the next 2 tanks to see if there is a change. Of course it cost $1 more a gallon.

If I read the CA law requiring ethanol correctly. They do not require gas stations to run ethanol. In fact those that do mix ethanol can go as low as 2% and up to 10%. The gas stations we bought our gasoline at did not have ethanol in the gas. 1) the fuel pumps were not marked. 2) I asked them if their gas was non ethanol and they said yes it was. BTW we paid $3.59 for non-ethnoal unlead reg.

You are correct that CA does not demand that ethanol be used. But it does require an oxygenator. CA outlawed MBTE in 2005 and ethanol replaced it. CA also does not have to post at the pump the ethanol percentage in use.

If you want to find stations that don't use ethanol I suggest a site like pure-gas.org

I do use pure-org. My trip to NV and CA found quite a few non-ethanol gas station that were NOT listed on pure-org. You look at the size of NV and CA and only 26 non-ethanol gas station are listed. OR and WA has 428 listed non-ethanol gas stations.

Nonetheless my mileage improved in NV and CA.

I'm not sure I agree with the summer/winter blend. My reason is, depending on what city fuel is delivered to this winter in Oregon. Summer and Winter blends were available to be deliver. We had to two different RVP's to choose from.

Rvp ?

Summer-grade versus Winter-grade Fuel - HowStuffWorks


During the summer, pollution is a frequent concern due to increased levels of smog and ozone, which can harm the lungs. Summer heat boosts the formation of ozone, while the appearance of an inversion layer -- an immobile layer of air -- can trap pollutants in the lower atmosphere [source: EPA].
Summer-grade fuel has a different Reid Vapor Pressure (RVP) than winter-grade fuel, which contributes to its being (marginally) more eco-friendly. RVP is the vapor pressure of gasoline measured at 100 degrees Fahrenheit. Fuels with higher RVP evaporate more easily than those with lower RVP. A particular fuel blend's RVP is based on the combined RVP of the ingredients that make up the blend. Regulators worry about this evaporation because it contributes to ozone formation.
Gasoline must have an RVP below 14.7 PSI (pounds per square inch), which is normal atmospheric pressure; if a fuel's RVP were greater than 14.7 PSI, excess pressure would build up in the gas tank, and the fuel could boil and evaporate. Depending on the part of the country, the EPA's standards mandate an RVP below 9.0 PSI or 7.8 PSI for summer-grade fuel. Some local regulations call for stricter standards. Because of these varying RVP standards, up to 20 different types of boutique fuel blends are sold throughout the U.S. during the summer [Source: Slate].
Because RVP standards are higher during the winter, winter-grade fuel uses more butane, with its high RVP of 52 PSI, as an additive. Butane is inexpensive and plentiful, contributing to lower prices. Summer-grade fuel might still use butane, but in lower quantities -- around 2 percent of a blend [Source: The Oil Drum].
We know that gas prices go up during the summer, generally around Memorial Day, but when do companies start producing these different summer fuels? The EPA defines April to June as the "transition season" for fuel production [Source: EPA]. Refineries switch over to summer-blend production in March and April [Source: EPA]. Gas stations have by June 1 to switch to selling summer-grade gas, while terminals and other facilities "upstream" from pumping stations have to switch by May 1 [Source: EPA]. Following the summer driving season, companies switch back to winter blends beginning in September, with the first winter increase in RVP allowance occurring on Sep. 15.
In a 2001 report, the EPA claimed that "roughly 75 million Americans breathe cleaner air today due to [the seasonal fuel] program" [Source: EPA]. Still, the increased price, combined with the use of controversial additives like ethanol (which is less energy efficient than gasoline and produces more smog) and methyl tertiary butyl ether (MTBE), means that the program may still have its detractors.
