New air intake

Is it worth it? I've read (from the vendors) a better intake can improve mileage and boost performance. Is there any truth to this? I'm sure this has been discussed before, but I didn't see anything that answer this question from searching the forum.

V/R,
Tom

Simple answer, no. Intake is still pulling hot air from the engine bay, and depending on which style you buy, easier to hydrolock.

Banks Dyno day!

I have the banks as well I did it mostly for sound, I will say it sure didn't hurt my mileage or power

A vendor that is trying to sell these products is probably going to say that.

Anyway, are you talking about a drop-in replacement air filter or a CAI? There are stories on the forum where a dealer voided a warranty on an otherwise covered engine repair because the owner was running a Mopar CAI.

I have banks as well because of the dyno chart I saw and it looked promising. I have a Magnaflow pro series tip down exhaust and it's loud I'm surprised it didn't get any louder when I installed my banks. I can feel a difference on 1-3 gear tho no more lags.

Search for "Cold Air Intake" or CAI. There are a lot of threads, usually asked once a week.

All the naysayers obviously can't read but can sure as hell type. There are threads WILL DYNO CHARTS showing mild improvements! Search bank DYNO day. Try a google search with wrangler forum+banks+dyno, it works way better than the search function within the forum

I love mine and notice a little improvement in power and mpg. Is it a super charger- NO. If you want to squeeze more power for a price than give it a try. Guys who can't read or back up there mouth should shit the #%^*! up. So sick of the ignorance on this subject!!!

Banks Dyno day!

There are multiple threads WITH DYNO SHEETS, discussions, etc

I'm gonna get me some chloroform for these other numbskulls

As for this thread yes it did happen but as far as I know no final resolution has been posted by the Original Poster and we don't have enough info I run that same filter and have run in insane conditions back to back: desert/12,000 foot altitude passes/snowstorms/sand storms/ Something happened beyond a simple filter failure with that other warranty denied thread

But hey read all the info for yourself and decide (like you are doing).

Don't take anyone's world for it. It's your Jeep, not theirs, not mine

If one thread about a warranty claim can sway you. Then let me tell you about two people running that who put on huge miles:

My buddy 35,000 on his 2013 Arizona/Minnesota/California/Colorado

And myself 48,000 2012 same regions of roaming

Both No air filter or engine related issues whatsoever

As well it did. We have a Maximum Care lifetime bumper-to-bumper warranty and there is no way I am going to do any extensive mods to our Jeep that can in any way affect that warranty being voided.

The case of the engine warranty being voided and leading to a rather expensive out-of-pocket repair for the owner was due to a genuine Mopar CAI running on the vehicle. It was also installed by the dealer, if you recall.

You can post all the "my buddies did this, my buddies did that to their Jeep" stories that you want and say that it didn't void the warranty. Not yet, anyway. It's your Jeep, your risk and your money.

Cold air intakes sound cool.
Keep the filter clean and well oiled they do keep the dust out.

If your looking to increase in horsepower from a small displacement V6 pushing a 4,500lb vehicle with oversized tires by simply replacing the airbox you might be disappointed.

Removing hard top, back seat, spare tire, doors and going back to stock 32" tires will make your JK accelerate much faster than any air intake ever will.

Just ordered a Banks kit from Quadratec(shameless plug) and it will be here tomorrow. I bought it because it lets more air into the engine, which is what makes more power. Is it going to be a lot more power, noooope, but the intake combined with the exhaust and a programmer might help turn the soon to be 35's a little easier. I don't plan on adding a periscope anytime in the near future so the thought of hydro-lock is out the window. It is what I wanted, and I didn't need it decided by committee. Will let you know how it turns out after Christmas, since it is a gift from a family member.

There is no validity to this case, no documentation (pictures, paperwork, name of dealer etc), no follow up, nothing (last I checked). Putting a different air filter on a vehicle isn't extensive. Chopping off every control arm mount and welding on a completely new suspension system to the frame is, and I still had warranty cover a rear main seal (last Jeep). You can be pushed around but I won't be. If my control arm mount broke I'd be fixing it myself. If unrelated components fail then I'd expect a competent dealer to know the difference and be fair.

I also NEVER buy extended warranties through the manufacturer. They can deny a warranty on anything they want at anytime. I've seen it many times on friends vehicles with various manufacturers. I sure hope you bought a second party bumper to bumper warranty.

The difference is first party or second party. I trust my experiences and those of people in the 3D real life a tad bit more than some internet story. Since we don't know each other (I'm that second party to you), and I don't blame ya. But life is too short to buy a vehicle and not be able to mod it IMHO.

The sky isn't falling...

I've done intakes, exhaust, and all kinds of adjustments on my bike.

The result is usually a little more power in the higher rpm range, a lot more sound and fury, a loss of torque down low, and a few less mpg.

Yes but when the search in WF isn't sufficient/functional then we all try to help steer people to threads and our own experiences to make there own educated decisions

And no offense intended to anyone who has differing opinions on my end!

Searching for any dyno charts regarding the Banks kit on a 3.8L, no luck so far. Any chance you have any links?

It seems like just about everyone in these forums that have CAI's love them and report better sound, small power gains, and better throttle response. A guy I work with has the Banks Stinger package on his 3.6 and he swears by it.

The power of perception and marketing. $300+ for a plastic tube must do something.

X2

Save $300 and run no air box. duct tape a filter to the TB to keep dirt out

X2, this is a very realistic solution, but to make sure that the quality and integrity of the install is maintained, you must use a quality premium roll of duct tape, THE PREFERRED BRAND IS 3M...............

Fed Ex just dropped off the kit at the house. Should I attach the whole cardboard box to the intake housing with Gorilla Glue? No need to take it out of the box since the components inside don't serve any function, right?

I did this with my YJ. Well.... No duct tape rofl

A short tube, c-clamped on a filter. $50 tops

Yes. The DYNO charts from private parties at local DYNO shops have been funded by the evil empire of CAI manufacturer alliances. It's is all a complex scheme to deceive the world of very mild horsepower gains. They even can download data via the internet onto computer screens and in databases using CIA (not to be confused with it CAI branches/entities) monitoring systems that target all DYNO equipment facilities across the world. It's all quite complex. I doubt you'd understand, unless of course, you speak naysayer tongue and don't even really have a CAI. Good work rebel scum for bringing your uniformed truth and logical fallacies to light!

The real truth is we are just all greenies driving jeeps for their suburb fuel efficiencies and just love to not be a part of this disposable world. We buy a washable filter, use recycled OR reclaimed water to clean them, instead of tossing ours away like the rest of your tree killing bastids. We also don't wrap our winch lines around trees because we're SO much smarter than you that we use tree savers. That's right. No more conspiracy theories. The greenies are behind this whole CAI thing- cats outta the bag. Are you gellin'?!

Another little known secret is the water used to clean the CAI is then put into a vitamix with some raw organic protein powder and several $100 bills (because we love blowing money too). This is called a green smoothie. That is yet another reason why we are called greenies.

^^^This is a great ideal, (use the filter and the box), double filtration, better know as a two (2) stage air cleaner..............Lol.

My 1974 CJ5, had the 304 V8. The challenge with the air cleaner, that sat on top of the carburetor, was to make sure that the gasket between the two was in good shape. It would get brittle real easy, and then not seal. Then next was the wing nut, that tightened the cleaner to the carburetor, well if to loose, then it would suck in silicon "Dirt', but if tightened to much, then it would warp the choke housing, causing the butterfly to stick. It was just a very poorly engineered design!
Thank goodness that we no longer have to deal with them issues!

Unfortunately, the marketers of today, prey on those that don't understand CFM air flow needed, along with the proper absolute particle filtration required!

It's really no different then, some purchase these expensive very tight micron air filters for their home, not understanding, that their air handlers, are not designed for that reduced CFM flow.......

No one is saying that a CAI won't do anything. They are for the most part saying that for the 300 + dollars spent, there would be other things that would do it better. The CAI is just a minimal increase in power for the money spent.

If I understand DBW throttles on modern engines correctly, they work "progressively" for lack of a better word. I.E. just because you mash the pedal to the floor doesn't mean that the throttle plate opens up all the way. In a DBW system, when the gas pedal is pushed down, the throttle plate will open progressively as the engine builds RPM; and won't fully open until the engine reaches close to full output RPM (like around 4500-5000). Therefore, at lower RPM ranges; the throttle plate itself is the restriction.....that is what it does. I have used the analogy of the intake from an SR-71 before, so it will do now. No matter what the intake size, the throttle plate only lets so much air in.So the BEST way to combat this is with a tuner that will open up the throttle plate sooner at a lower RPM range. Or go with super/turbo charging.
Now if we were to increase the volumetric capacity of the engine... bore, stroke, or increase maximum RPM to where the engine itself required more air, THEN we need to start addressing the efficiency if the intake system; at which time a larger throttle body itself would have to be considered.

The old school hot rodders used to do these things... buy an engine that was 3XX cu. in. displacement; redlined at 4500 RPM. Then bore it, stroke it, do a bunch of head work and have an egine with 4XX cu.in displacement and redline at 7500 RPM which now required a whole bunch more air. So they went to 4v carburetors, then 3 2v, 2 4v, and in extreme racing situations 8 single v carbs with velocity stacks on them. This is where a lot of the thinking has come from. But, all of these things get into spending big bucks.

So, with all that, for $500 or less; a tuner would probably be the best option, but without the CAI, it will not sound as cool.
