- Well, Since I'm testing all of these intke options I figured I would give my thoughts on the factory filter and size it up against the Hellcat filter as well as an AEM Drop in and the filters from the Mopar CAI and the Legmaker True CAI.
Basically, the stock filter flows 731 CFM when clean and, well, not near enough when at full filteration capacity. By contrast, the Hellcat filter flows roughly 1100 cfm when clean and about 700 when at full operational filtration capacity. I have no data on the aftermarket filters but by the looks of them they will sacrifice filtration capacity for performance.

hey bob ,,first time commenting on your channel or youtube for that matter,, I have a 2015 scat pack that i bought new 2 yrs ago and i love the car,,the first mod i did when it was a few weeks old was put in a aem filter,,after that i really didn't think much about changing out to something else cause i thought it was good ,never really noticed any change in response or power but it was brand new at the time and quite frankly it has gobs of power anyway ,,last spring i put in a hellcat airbox but continued to use the aem dry filter no noticeable change ,,but there's a cool factor in having air sucked in thru the headlight,,after checking out your channel i decided to go with a hellcat filter,,put it in tonight and yea man i noticed right away the response,,even the sound, was better according to my butt dyno lol,, so thanks man for the info and the time you put on your channel,,,one thing id like to mention is buying a real hellcat filter was a little time consuming online because most sites sell fram or other brands but are a generic filter that fits all ,srt ,,scat pack and rt but doesn't flow the same as a hellcat filter ,, so to your subscribers beware,,, found mine on rock auto big jon
You made my day, I just ordered one using the link you provided. I'll probably just use it on my track days, and keep the stocker for my daily drive. As usual, useful, tested, verified advice from your channel. Outstanding !
Very happy to help and thank you for the kind words!! For the price you cant beat it. Considering it went 11.60's (corrected to 11.70's) with about 7000 miles on it on my car I can attest to its effectiveness.
Thanks for the research, I will be using the hellcat filter from now on.
Wally World happy I could help!
Thanks for this video!! I just purchased a sxt Challenger, now I have the hellcat pieces for the intake. Returning the K&N drop in.
This is awesome, Thanks. I have been considering doing this test as well but at Atco Dragway and seeing if my runs change from filter to filter with maybe doing 3 runs per filter and using the average.
Thanks, B Mason. Older video, but good timeless content as always...
really like the video I did some research and the Green Filter Part #7139 flows 1890 - 1512 cfm alot more than the Hellcat filter
According to K&N's website, their drop in filter for the 392 is rated at 780.2 cfm at 1.5 inches of water. This would be a slight improvement over stock, but not sure if it's enough to show up on a dyno. The dry aftermarket filters seem to flow less than oiled ones, so I would be surprised if the AEM out flowed the stock filter.
FYI I chatted with AEM on the drop in filrter they say it is 780.1 cfm.
Thanks for the info. I think i am going to keep the K&M filter.
Man, I have been meaning to comment on one of your videos for a while. Just couldn't decide which one and didn't have time. Now I'm sitting here recovering from hernia surgery watching ALL your videos so it seems like a good time to share some feedback.
You have got to be the most laid back, friendly, informative and honestly helpful car guy on TH-cam, by a pretty big margin. Never hear you grasping at straws to justify a mod, and always so straightforward about your experiences and recommendations. I've never watched one of your videos and felt like "omg I need to buy this;" if anything you've probably saved me a ton of money on intake, exhaust, and other minor mods that internet bench racers insist make "night and day differences" they can feel as soon as they think about starting the car.
And again, you present all that great info without a hint of ego, just down to earth experience and a really refreshing friendliness.
Thanks again for this video (I'm running the hellcat filter in my SRT 392 right now) and all the rest of them. Keep up the great work and keep having fun doing it!
I truly appreciate the kind words. Very humbling. I try my very best to be as honest and forthcoming as I can be. The goal of my channel is to make you feel like we are hanging out in the garage or the Lounge just chatting about car stuff. Thank you again and GET WELL SOON!!
The Hellcat filter should have come on the 6.4L models
Thanks for the information, I just bought a K&N and rethinking it. But if you don't have data on the K&N filter, I still feel that filter will suck more air, granted probably more dirt but the spray would catch more of that as well so I still think it will be fine and suck more air. Thanks
I use the K + N drop in, stock box on my 392. Seems to run great... 6.03 cfm per square inch according to K + N, where the paper drop ins are 4.95 average.
Thanks for the intel.
Thanks so much for video! I installed hellcat air filter on my scat pack 2020 . It is different! Car run better and breath well
I still keep my stock airbox because i think it’s already good with hellcat air filter!! I also put the borla atak too. Sound amazing!
I installed lower hellcat airbox today!! Love it!
@@joenguyen5263 whats the most notable difference with the hellcat box? I have a 2020 SRT Jeep that I just purchased a helllcat filter for after watching this lol. My man B. Mason already saving me hundreds of dollars on pointless CAI systems
Corey_392 i return the hellcat lower box
Because it’s not help that much! I still have the hellcat filter! That’s filter is amazing! Car breathe so smooth!
Joe Le when you say it doesn’t help much what are you referring to? I know it won’t add HP but did u notice any difference in throttle response? Intake temp?
I know a lot of us performance guys appreciate the time and money you spent on this endeavor. It's real world results that count, especially if you are racing where every hundredth counts. Having said that I've spent too much money to even think about on CAI's over the years and just recently said to heck with them. I just drop in a $50 K&N filter and call it good because I know I won't have to clean it but once a year. Yes I've gotten a little bit lazy with age, but I also realize that most factory intake systems are pretty darn good right out of the box. Again great video sir and please keep up the great work!!
JetTech1966 Thank you very much! I'm with you on the validity of car's on modern cars. That's the whole reason for most of my testing. most of what I test is in direct response to aftermarket claims of "gains". when I spend my own money and put them to the test the results usually wash out unfavorably for the claims made.
That is for sure!!! Those "claimed" gains are a figure that some marketing guy pulled out of his butt....lol....Of course some "add ons" might give you a 10 to 20 hp gain on the dyno. Awesome. But you won't feel it. You can hear it if we are still talking CAI's, but you won't feel it. Well placebo wise you might...Modern day engines are so well tuned.
I remember my 91 5.0LX coupe I had. All you had to do was remove the air silencer in the fender well and put a K&N flat panel filter in it...bam....cold air intake. Then move the timing from 10' to 13'....bam..seat of the pants hell yeah!!! LOL.....unfortunately those days are gone but these days are pretty awesome too.
I miss my Foxes so much!! You are absolutely correct. A turn of a wrench, a twist of the dizzy and boom! There is your tune! Those cars taught me so much.
Me too sir. I had a ball with my 5.0's, I actually had a 90 and a 91 at the time. Simple but yet refined. Gains were easily had with basically a timing light and 93 octane fuel...I miss my old 5.0's.
B Mason - based on your testing on several videos, would you say the stock Hellcat airbox w/ the Hellcat filter, stock HC Airbox w/ K&N drop in, or Mopar CAI works better for the 5.7?
@@ll5352 lmao @ turd
Did u ever try the aem filter? If so did it work well.
I think there was a table for all aftermarket drop in filters that had the CFM values compared to 392 and hellcat filters. The AFE one is pretty good. They also claim better filter action efficiency and dust capacity than hellcat.
bezaldo7 if there is I couldn't find it. if you know where it is let me know
As noted in the video the only way to increase CFM is to increase media size or decrease filtration. The way aftermarket drop ins increase CFM is to decrease filtration.
Just wondering what your thoughts are about adding the factory under hood ducting from the hood scoop to air box for a ram air like the TA comes with.
Thx
James B ive looked into it. I don't like the shape of the inlet tract on the TA.
Thanks, especially OEM STUFF.
where can i get the hellcat filter??? i have a 2019 scatpack charger
Do have the part# for the "Hellcat" filter to be used to swap out for the stock 392 filter? I am gonna put in the Hellcat airbox on my 2019 Widebody 392. I am seeing 2 part#s forthe filter: 1. 68172459AA and 2. MAHLE LX3482. Just want to make sure I get the right one.
This reply is a little late but I had the same question and have found out there the same filter the part number are different the 68172459AA the Mopar pn and the LX3482 is the MAHLE pn both numbers are printed on the hellcat filter so get the one with the best price. Look for P/N on filter at 1:50 in his video
hey I love the review, but only one question. after asking around and doing research the stock heads only allow 340 cfm. whats the point of allowing more when all it is going to do is get bottlenecked down at the heads? seems to me that even dirty the stock filter allows more then enough air flow for these stock engines and any and all changed would be a waste of money.
That is a flow rate PER HEAD but at what valve lift and what vacuum? But anyway using your figure that would be 680 CFM for the pair.
Hey Josiah have you heard any new information that would change your outlook on this set up? I’m trying to optimize my 6.4 as much as possible but it seems to be all for naught if it’s not intake+heads+exhaust+tune
@@danteblrmf304 hey sorry for the delay in response. I honestly do not have any better information for you. After having my 392 for a little over 3 years I was very unimpressed with the ability to upgrade and get more power out of the engine without literally tearing it apart and rebuilding the internals etc etc. I parted ways with the Charger and moved onto something that I am much more happy with now. Best of luck to you with your build though and I hope it works out to be something you are happy with!
I have the 5.7 and I did run the AEM dry flow for a few weeks. I lost 4 mpg so I dont think the air/gas mixture was adequate. Popped the oem paper and I'm getting 19 mpg. Haven't tried the hellcat filter yet.
Scott Free you should try hellcat air filter! I put it on my car and car run way better!!!
@@joenguyen5263 I have a hellcat filter in now. Gave up on the K&N's and the AEM .
Scott Free yeah! I think to put the lower airbox hellcat on but I don’t think it will gain a lot hp. Car run and sound amazing ( borla atak+oil catch can+ hellcat air filter)
Im assuming the air filter you linked for the hellcat drop in will fit a scat charger?
Wyatt Howell it will drop right in.
Awesome appreciate the response
Ok I have a 2019 challanger rt scatpack. It has the 392. Should I get the helcat OEM air filter or hellcat k&n air filter
Hellcat OEM.
@@bmasontv thank you sir
Is the intake for the srt 392 Durango the same size as the charger/challenger box? I’d love to grab a cat filter if it fits!
Unfortunatly no. A k &n drop in will work well in that box
It's great to look at the flow of the filter itself, but would it be smart to consider the flow capability of the intake itself? (Air box, tube, and other components)
Thank you for the info on the Hellcat filter, I will be making the purchase for my scat pack. Also the cam you installed on Racer X buddy charger, would you have the specs on that one, duration, lift?
I do not give the specs of the grinds of my cams. That said, duration and lift are only a part of the cam specs. Lobe profile is just as important. Giving you the lift and duration would only confuse the comparison without mid lift figures.
B Mason
Basically you can modify a camshaft specifically for my Scat Pack?
B Mason
I apologize, I should ask you if you would be interested in grinding a camshaft for my car.
@@jeffswint4675 get with Doctor Differential. We can put something together for you. Keep in mind, I do not do a one-size-fits-all camshaft. We take into account the use of the vehicle intake manifold exhaust, torque converter and Driver sensitivity to drivability issues. As well as weight of the vehicle. So, in saying that. Be honest. If you're looking for a cam that's going to still be Snappy under partial throttle yet yield a decent game up top, we can do that. If for example you want something that chops really hard, we can do that too, just understand there will be drivability issues with those types of cams. And everything in between.
B Mason
Do not care for the big chop, something close to normal, but with a bit of a bite. Sleeper style would be great! Thank you for talking to me, I really enjoy Your and Racer X videos!
I would be curious how far back the airboxes/filters are interchangeable. I have a 2011 but the Hellcat did not come out till a bit later. Are the Hellcat filters interchangeable with 2011 392s? Dodge being cheap may mean the kept the design the same but who knows. Again, a great segment.
Doug Kessler they should be. the air boxes seem to be unchanged. The only real difference is in the placement of the intake tube for the PCVcircuit circuit on the upper box. aside from that the filters should work.
Great information I was about to go with k&n airfilter, by recommendation by a shop, do you have an opinion base on research of whether or not tp upgrade my cold air intake to mopar one from the stock?
Everette Devan I'm not a fan of it. I prefer the hellcat filter in the stock airbox.
@B mason what about the hellcat air box and tube that connects to light was gonna put that into my 392
Best intake in my opinion.
@@bmasontv thanks brother can’t wait until winter is over up here gonna get to the mods in spring
I have an ignorant question (I’m a pretty fair medic & firefighter, but cars & their donks? I’m like Oddball in Kelly's heroes- I just ride 'em baby, I don’t know what makes them work)
Aren’t performance air filters less able to filter air? Using any of these, wouldn’t I be letting more foreign objects into the motor, wearing it out quicker?
It seems to me air filters must be a compromise between filtration & volume of airflow, & performance filters must filter less thoroughly than everyday run-of-the-mill filters? So as much as I’d love to make my srt8 bellow, & as much as I’d like to improve mpg, a performance filter will shorten the life of its engine?
Like I said; don’t know much about cars, but if you help me understand this, I’ll tell you about the organ of zuckerkandal.😺
Thanks in advance for the positive waves!
As a general rule you are correct, performance air filters and I use the term loosely, typically do not filter are as well. They sacrifice filter capacity for air flow. Thing is the Hellcat filter sacrifices nothing to achieve the airflow that is capable of.
Is the hellcat filters only for 6.4? What can I buy for the 5.7 r/t to achieve optimal air flow?
How often do u change ur air filter and do u run a oil catch can
Jake Derr I've only changed it once, may have had 5000 miles on it. I dont drive this car that often. I do have a catch can. I drain it fairly regularly, roughly every other tank of gas. Not that it fills up that quickly, I just don't like it to have anything in it at all.
B Mason thanks for the response! I have a sublime 392 challenger and your videos are extremely helpful. Keep up the great vids
hello. i cant seem to find a hellcat filter online to buy one. i have a GT that i put the hellcat airbox into and turn signal hose. I noticed from the seonsors that the temp is much lower. i'd like to upgrade the filter next, but, i can't seem to find one. where do you shop? and thank you for making this informative video!!
You can find them at any local dodge dealership. Just make sure it has the Mahle name brand on it.
@@bmasontv thank you!! 🐇
What do u think the best CIA performance wise
Mohammad Albasri for outright, overall performance the Legmaker true CAI is tough to beat. That said I will stay with the Hellcat air box and filter. much easier to install and far easier to maintain. and about a third the coat
Mohammad Albasri Stock.
The stock box is better engineered for flow. All the CAI does is make noise. Put a better filter in your stock box and be ahead.
I’m late on this video too. But better late than never. I just put in an AEM dry filter in my ‘21 Ram Hemi and I’m tell you , it made the truck feel sluggish. Like it has to do more work in order to perform well. I thought it might be the placebo effect in reverse. So after a few days , I put the stock filter back in and my truck immediately felt more responsive. Could it be all in my head? Possibly. But I’m sticking with the stock filter. I wonder if someone makes a higher flowing stock-type air filter(?) Great vid 👍
AEM is not as good as stock. Not sure how they sell those filters. Tested as worse of the group. Stock included
Ok so I wasn’t imagining it. Good to know I’m still sane. Thanks for the reply. Would you recommend any other brand of drop-in filter? I’m currently watching all of your videos in no particular order. Good stuff.
@@shadowdemon5730 as long as you keep it clean, the K&N works pretty well in that application.
@@shadowdemon5730You’re not the only one that felt that sluggish feeling with AEM filter. Same thing happened with me. I just decided to go with the Hellcat stock air filter. If you wanted aftermarket drop-in-filter though, I heard Green Filter is a good brand.
Can run no filter Just on track short time ?
I see no reason why not, carbureted guys have been running with no filter for forever. I just don't know that that would do any good, considering that these modern filters flow so much. I doubt they would effect power output. Not less you're making a whole lot of horsepower. And those guys never run filters
Hellcat filter ....Its in my box .
Thanks for another great comparison. You mentioned the Hellcat stock filter cost you around $20-something dollars shipped to your door. Can you tell us what vendor has them that cheap? (Genuine Mopar not generic)

If not which one you recommend for my Ram
Thanks
check out video did a lil test on pretty much stock filter Vs K&N
Quick question about the Hellcat filter. Are they the same size as the stock 392 filters?
Expel10 yes they are. Exact same size, direct replacement.
You have nearly $800+ in air filter/intakes on hand (e.g. LegMaker, Mopar, Hellcat box). You removed the Legmaker, the clear winner in terms of being a true CAI, and put on a Mopar kit - which I believe was after a Hellcat CAI converson. That's a lot of time and money for air filtration. If the Legmaker was the winner in terms of CAI, why remove it since your car is a weekend car? I mean you went trough all the work... I believe your final choice was the Hellcat box/filter exchange. I have to ask. Why bother with a $350 Mopar CAI? If you did not have a 2015/2016 where the Hellcat airbox was an option (I have a 2011 SRT8), would you do the Hellcat drop in filter swap only or one of the other setups?
Lastly, as a gear head - does the open airbox like the Mopar increase intake/exhaust feedback or cool sound? :)
Great questions! The main reason for all of the intakes is purely for testing. I wanted to cut through all the BS and Bro Science and find out which is actually "better", if there is such a thing, as it pertains to air filtration and power output. The Legmaker may make it back onto the car at some point. My main issue with it was the fit and installation. Think in terms of "beta testing." It just doesn't fit that well as delivered. I will be fabricating some brackets to solve that issue. The Mopar made it to the party in the same spirit of testing as the Legmaker. An open element filter with a heat shield vs the legmaker seemed to make for a good comparison test. Plus, it is a Mopar part so I figured if I was going to give any open filter a chance, Why not go with the "factory" part? If I had the previous gen Challenger the intake I would recommend is actually the stock inclosure with a hellcat filter. It just works VERY well. If the LMCAI fit better without modification it would be a close second but you simply cant beat the price of just a HC filter in your stock box. As to the sound... Not much. The HC filter will translate a little more throttle blade whistle which is kinda neat, but overall, no real change that I could tell.
question? I keep trying to installed the oil catch can a uprproduct, the check engine light comes on because there seems to be air coming from the small attachment hole.. When i put the factory tube back on it back to normal. totally confused. What are thoughts of the problem, its a simple mod at least i thought it was.
Everette Devan make sure you seal the threads and also make sure the petcock, if equipped, is closed.
I have a 2019 r/t will the hellcat filter fit and where do I buy it?
Yes. Amazon
This guy needs to update this big time. Why nothing about K&N, THE premier air filter place for racing. They have TONS of data there.
Considering the data on the K&N Filter shows that it doesn't flow as much as the stock paper filter, coupled with the fact that I did a data acquisition on the green filter, commonly known to be the highest flowing of any of the drop-in filters and found absolutely no difference in data. No change in kPa whatsoever. No change in time stamp acceleration either. We have several cars that have backed up this test result at the drag strip. Furthermore, we've been able to show no real gain in performance with an aftermarket cold air setup. Granted, this is only at roughly 650 - 750 horsepower to the rear wheels between the three cars. The filters simply did not offer any Improvement in E.T or mile an hour. Which quite frankly is annoying, considering I have a brand new green filter and cleaner kit that I have absolutely no use for now.
th-cam.com/video/GS69owXpGdY/w-d-xo.html know it's been awhile since this video was posted but this explains the differences with a performance air filter and the difference in horsepower and torque with a bit more data.
So what if u race with no filter ?
It's funny you should ask that. I just did a live show where I date log the car with the filter in the car, then removed it and logged it with the filter out of the car. literally an a - b - a comparison and the data shows that the car prefers to have the filter in the air box. KPa went up and air charge went up when I put the filter back in. This agreed with the data that I took before the video started with my data Logs with the filter in the car it was repeatable. So to answer the question, the car would not benefit from the filter being removed based on the data that I have. Feel free to check out the video. It should be under live streams
@@bmasontv I guess im getting a hellcat filter, thanks so much !
I just got off the phone with K&N, she quoted me 790 CFM on their drop in filter 33-2460
I think paper air filter do a great job and the K&N when maintenance properly by having two of them or having all day to do the cleaning process are fine as well.
anything but K&n should be fine. K&N doesn't filter at all.
Anything larger than a small chicken gets trapped right away in a K&N! (that is how they can advertise a large flow rate)
