Need some real advice. Getting one of the two for my 3.6 - just don't know which. The K&N would save me about $100. Is there a major difference in the two? Not a big car enthusiast per say, and I love how quiet the cabin is now, would just like a bit more throttle response/acceleration.
This is a great question! I was thinking the same thing. My question is, which one is quieter? With 8 speed tran I don't want daily driving to be louder.
Hi there,
In my case I had the same concern..wanted a little bit more response but was concerned it might end up too loud.
I got the K&N and I can say very happy with it.
You dont hear it all in normal use, you wouldnt know its there, that is unless you press hard the accelerator, then you hear it, nothing that will bother you, its a real nice low tone sound, not sure how to explain it...but I recommend it 100%, I got it from Amazon.com, installation is pretty simple, and since everything fits perfectly without modifications the wost scenario is that you can take it out and go back to what you have now.
Rgds.
I have the K&N on my Hemi and really enjoy it. Pay no mind to the haters. It's your ride. If it give you more enjoyment go for it. It's not going to give you any noticeable performance gains but on my Hemi it lets out a nice intake burble on load moving into a nice roar on full throttle. Just cruising around town or on the highway you don't hear it.
Just installed K&N on my hemi and I lover it. The sound is great when you get on it. Not much noise when normal cruising. Throttle response, my be a little but it probably is just me thinking it's better.
Looks a lot better in the engine bay now. I when with the black plastic material tube and couldn't be happier.
After reading a lot about this I decided to NOT install on my 3.6. I understand CAI makes a big difference for a Hemi, but for a 3.6 I couldn't find much information that supported it making a difference in performance.
If you do go ahead and get this, please update thread with how you like it and specifically if you notice a difference besides sound.
My 2-cents on this question of mopar/k&n cai's -- I choose to go with the mopar vs the k&n only because of it being a mopar part...plus I like the look of the mopar over the k&n too....corny huh? I've had k&n cai on other SUV in past and my comment goes for it too. Well as for sound....very little notice from oe sound only time you notice you have a cai is when you step on gas from a stop or to pull away from traffic. And still noise is low and not that noticeable. Plus k&n goes for $267 i got the mopar for $315 at autopartsmopar thru amazon. In case anyone cares to know or possible want.
There probably is minimal improvements to my hemi. I was thinking about future mods that may come like exhaust, throttle body, and tune. I don't want a loud exhaust thought. Maybe make a custom set up with magnaflow mufflers welded in from the stock suitcase and leave everything else stock. Still worried about being too loud. Just want more of a hemi sound.
Spec sheet on the K&N show 10hp improvement at approx 5500rpm.
What that means is when you hit 5500 rpm might notice a little more pick up/ response.
you should never be hitting 5500rpm, unless tyring to pass someone @ 40mph or more.
The "noise"/ "sound" will be a little "deeper" but as far as performance goes, you wont even notice it, with either. but it will look prettier under the hood....
Just saw a pic of the K&N setup and I can now say I like the Mopar much better. Fit and finish looks better, metal tube over plastic, and a better shroud.
I bought a used airraid CAI off of a fine member of this site for my 2011 3.6. The price was good. Have I noticed much difference probably not, both performance and sound seem about the same.
Would I buy again? Maybe, again the price was good. I probably should have gotten a V8, but the deal on got on this car was good so now I am trying to make it a little more beefier.
Anyone that says an intake for the hemi is useless is a complete fool and has no clue what they're talking about. The fact that this 5.7L engine breathes through a 6" wide snorkel that immediately goes straight down then straight back up through the air filter than a 90 degree turn into a sound suppression box then back up to the TB tube should tell anyone with any tuning experience that a CAI will make a large difference. The computer is tuned from the factory to use the shitty airbox but that still has nothing to do with a piston pulling down and encountering restriction due to the maze that is the factory intake. You let that piston move down easier it frees up power that is there already, just suppressed.
in the 3 weeks I've owned my Jeep I measured a 2mpg difference with the CAI on a 150 mile drive and around town. I've been tuning since I was 16 and datalog damn near everything I own. Take it from someone that measures results and not useless hearsay.
Gas mileage has improved in every car I've owned during the firs 5k miles.
Your improvement in MPG can be attributed to engine and tire break-in.
It's really not as easy as shoving more air through your engine. Have you thought about fuel? Have you thought about tuning? You're adding an intake to your car when your ECU thinks it still has the stock intake.
You could actually be losing horsepower/torque depending on where you lie in the RPM range.
The air has nothing to do with the "piston pulling down and encountering restriction". I think you should look up how a combustion engine works. Specially how the fuel/air mixture is related to that combustion.
My Jeep has 20K on it. It's not break in and yes I am fully aware of how air/flow works. Yes it's true you won't get MAXIMUM performance from a CAI without tuning but why don't you try to suck and through a straw then a paper towel tube and report back the difference. It's the same principle. Air Flow ratio has no place in this discussion. A CAI will lean it out some but not enough to talk about. I only gas up at one station(shell) that does high volume and has a reliable ethanol content. People can believe whatever they want and do whatever they want to their vehicle but when people give false information and say there are no gains without a single shred of proof it's annoying. Same goes for the other way around. I saw 2mpg gain from one trip to the other with negligible difference in weather conditions.
The link below is the engine I hand built and tuned in my ski. I'm no tuning newbie. Don't believe it take a peek over at 3800pro.com
an engine IS a giant air pump and I built that entire craft, race it and have a full build thread on it. I also have several industry leaders in that area that will attest to my tuning skills. Turbo 3.8s as well. Oh, MoTec Nills and the VTECH guys as well.
What single fact have you proven? At least I've shows a Dyno graph of a 5.7 WK2 and given my personal experience when I added the CAI. Don't take that as an attack but I'll argue the hell out of something when someone has counter proof

You showed a graph from a vendor trying to sell a product that shows no evidence of how or where the test was conducting or if there were any variables.
There is no governing body when it comes to performance products so if you say your product produces X horsepower it's really up to the public to prove you wrong.
If you use Google there are plenty of myth busting tests that show CAI's have little, no, or negative effects. Many of them show real world scenario testing and not just dyno runs. If any ...the gains are shown at higher RPM and/or at higher speeds not reached on a daily basis by most drivers.
I wonder if one of the site's sponsors, like perhaps RIPP or other that possess a dyno can quite finitely answer the question as to whether or not a CAI by itself can increase horsepower. Or is it just placebo effect. "I spent money, looks shiny, must be better. MUST!"
I don't know either way, but I'd REALLY like to hear from someone willing that has a dyno. Either on 3.6, 5.7 or both. I would not look to the actual CAI resellers for confirmation on this. That would be a conflict of interest. Some people totally and completely fall for every gimmick blindly. Smart money questions everything.
Anyway, if anybody with a dyno that maybe has some bit of time, I'm sure we would all really appreciate the end all be all about CAI performance improvements or lack thereof.

I have a 2015 limited V6 and will be purchasing the lifetime warranty. I'm guessing the mopar cai will not void warranty but will a k&n cai void any kind of warranty? I wanna get a better sound and maybe marginally better performance and gas mileage, even though the V6 can really get up and go. Sure it's not a HEMI like the Charger I have but it definitely gets the job done. Thoughts/info?
Do what I did. Get yourself a $20 bluetooth ODBII receiver from amazon, purchase Torque pair your phone to the BT receiver and datalog before and after. Compare you MPG and see what you get. No one is going to pay dyno time for a CAI comparison without a tune going in. NO ONE.
I have never heard of it but all it takes is one asshole dealership. I had a P1SC SC kit on my 300c and it didn't void my warranty because I went to school with the owner of a local dealers kid and had my car serviced there
ImpOster, don't worry about what mofsteel says, he's full of crap. Me and him go into an argument about exhaust systems. The guy thinks an exhaust does nothing too and tried to tell me that I didn't pick up speed in the 1/8th when I have the time slips to prove it. I've ran the track after every mod I've done
Actually MOFSTEEL unlike the many K&N fanbois that post here is right on the money about the K&N CAI.
It will not increase performance by itself without other mods. AND your OEM engine management computer will negate the effects of the slightly increased airflow after a couple of weeks. The OEM tune will adjust the fuel and ignition curves back to OEM parameters as designed.
To realize any noticeable gains w/a quality CAI...... improved exhaust flow to go along with that improved intake flow must be coupled w/ a good tuner to change fuel and ignition curves to suit the increased airflow.
Lets also not forget K&N's oiled cotton gauze CAI filters while they do
increase airflow, also allow more dirt and fine particulate into your engine
than an OEM paper filter or an aftermarket synthetic media filter.
^ This guy again. I never said that an "exhaust does nothing". It varies on the application.
I'm guessing you may sure all variables were the same in your testing too?
Fuel in the car fuel tank
External air temperature
Engine temperature inside the car
Race track surface
Condition of car race track surface
Barometric pressure
Humidity
Variances between driving styles
It's not as easy as throwing a mod on your car and driving down your local track. I can't believe I'm explaining this to someone who claims to be a "mechanic". You'll continue to argue because you don't understand and I state facts and walk away because there's nothing more to be said.
So continue...

So what experience do you have guy? You keep questioning me but what have you done? And claim to be a mechanic. Hey go Google what 91B is. WHEELED VEHICLE MECHANIC!
and yes, I do check DA, I do run a full tank every time I run and I do maintain the same operating temps. I even launch at the same 2500 rpms every time.
That is a stretch Jeff. You took it out of context. He did say it depends on the application and putting an SRT exhaust on another application MIGHT NOT always yield more horsepower. It may in fact reduce needed backpressure and might actually hamper performance.
Just listen to the man. He is making perfectly fine sense with his list. There are far to many variables on a track. Your best bet is to dyno in a controlled environment. Far less variables.
He never directly said that exhausts do not improve performance. Not even close. If he did say it somewhere, you need to find a far better example in the proper context.
Its only a personal attack if you choose to take it as such. It might help if you were to post the tons of data you said you have.
But, im finding that people dont take kindly on this forum when you ask them to confirm their claims with evidence. They automatically think that the person asking the questions is calling the other a liar or that they are full of it. Just want data. Because anyone can say anything they want on the net. Right?
Anyway, i dont take sides.

Let me ask you this. When was the last time you fabricated your own exhaust and seen improvement in drag times and mph? And then have some jackwagon tell you that you don't know whats involved with a custom exhaust. I've been thru 8 different setups. I've seen increases and decreases so I think I know what I'm doing.
Also he needs to learn the difference between a mechanic and a tuner.
Mechanics (what I am) are responsible for the build. A tuner ( not me) optimizes the tune to take advantage of what the mechanic build.
i have the K&N fitted to my 5.7, i run a workshop and dont believe any gains are noticable, however it gives a nice growl with a bootful, one thing i did notice the intake temps are higher than the outside airtemps and climb rapidly when you stop. i wish i now logged this before i fitted it to see if any differences between the two. maybe someone with the oem intake and a ob2 reader can check, theres about a 5deg difference but this also changes depending how hot the outside temp is.
