Thank you for doing this test. I've always stayed away from buying anything Mishimoto makes.

RotoFab is the best because of the open cavity where the filter is. Yea, those closed boxes, keep the air cooler that is being sucked in and it looks purty with the window but they actually did a test with the factory air box. They literally just took the top cover off and dyno tested it, and instantly gained 15, with the factory filter and 20, with a K&N filter. So, that proves an open box CAI is the way to go.

Gr8 info. I've been looking for vids on this subject... and thanks for the new runs with AC off lol😇

Would be nice to see CAI comparisons on a fbo heads/cam car including the JLT 5", all options tuned to max power.

They usually add a tune with it which is where they get their "increase"

When the car revs down it sounds like a flying saucer landing!

Did you ever test the roto-fab? I didn't see it on your channel!

The CAI needs the tune. The car is tuned for the stock air box. MAF Sensor is moved further away from air filter yes it makes a difference and needs to have the tune for the new air flow of the CAI. The readings will be off.

So if the AC was on low, why wouldn't you just keep it on the same setting for the next runs? Condensation getting on the rollers?

wouldnt you think that when GM did their testing on their stock cold air induction system for the camaro that if they thought there was any way to pull a few more H.P.s and torques out of a stock enigne by changing the air box they would have done just that. i dont think changing over to a c.a.i. will make that much difference

You need the tune from GM that goes with the CAI intake. CAI makes the GM Performance CAI's and the GM performance comes with a GM tune that does not void the warranty.

Big 3 are in the horsepower wars, they won’t leave free hp on the table to make their intakes “quieter”. You don’t buy these cars to be quiet. Chambers in a stock intake can be there to handle airflow anomalies by adding volume where neeeded. I’m no engineer, but I trust the actual engineers who have looked at everything they can to get a few hp over their competition. Maybe CAIs will have more effect on luxury cars or trucks. Heck, my stock setup is a CAI with air coming in from a hood scoop, headlight and fender.

Have you thought about testing the air raid cold air intake?

In an everyday aspect your hood is down. I know stock airboxes now for the coyote and the GM can flow more than you'll produce NA. Can support up to 500+. Best thing to do is a drop in filter. Do this test hood closed and you'll see even crazier results. The open filters will pull in some engine bay air where stock pulls only external air.

Well the Car is stock tuned so wouldnt it make sense for the stock intake to make the best performance? Any other intake would only show peak performance IF and ONLY IF the car is tuned for it. Wouldnt that make the most sense?

Sorry but I have tested EVERY CAI kit out there, on 5.0's, 2004-06 GTO's and Camaos 4th, 5th and 6th gen, none of them make any power to write hone about (under 4 hp). These tests must be conducted with the "hood closed" in order for results to not be skewed. Putting airflow over the air intake that is not there while actually driving is called altering the facts. Tuning/speed shops are in tbe business of making $ and snake oil sales. I've been on both sides. Also from a flow dynamics stand point. Every 30° bend in tubinf creates a choke point that reduces flow by 6-8%. On the cars I mentioned theres close to 60°-70° bend, so 15-17% airflow restriction. That translstes to a power loss of about 23-28hp losses. A straight in flow would eliminate this, like the old C6 vettes with a air intake vent/slit on the nose of the hood and on older pre 2016 5fh gen Camaro V8's. Problem is the air intake tubes curved to much.

Sure you selling that rear diffuser behind you?

Was the plastic baffle that seats between the grill and radiator removed?

Is the whole Dino controlled by your cell phone!?

At 23:35 Younger Hulk hogan walked through the shop!

Cold air intakes, headers, exhaust mods do nothing without tuning the car with them.

The worst thing someone could do is buy you a Dyno machine haha. You would just be gone from 5am until 10pm every night testing all these aftermarket parts haha. Then the combinations. To finish this up for you all, I have a stock 2014 Camaro SS, almost new still (4889 miles). Been garaged and driven minimal. Nothing upgraded!. Ill get the RotoFab and do a before Dyno with stock, and then install the RotoFab and do a Dyno test. Ill wait 1 week after driving with RotoFab and do another Dyno test. Then upload it here.

Good Lord man stock boxes tuned too stock box!!! Go dyno tune with a rotofab and then I might agree with you been there done that!!!

At 23:35 The younger Hulk Hogan walked through the shop!

Thanks so much for taking all the time and doing the work showing us the results. I am little surprised as well. You just saved me $300-$400 bucks though. :-)

Can you really test the effects of a CAI while the car is standing still with the hood up? I was under the impression that a CAI improves engine performance by drawing in cooler air from the grill instead of breathing the heated air swirling inside the engine bay.

Now we have to add the obligatory scandal title. How about "intakegate"! Great video Matt, you are truly doing a service to us 6 gen owners.

dude awesome video! I installed the green drop in filter in the stock box. the reason why is because I looked at the stock intake and thought there is no way it's restrictive. I will install the throttle body and msd manifold with testing. it will be on my channel when I get the installation done. also did some exhaust mods to the stock exhaust and explain in one of my videos. thanks again for making this video!

looks like i'm gunna keep rockin my stock intake thank for saving me a buck

Thanks for making this video. This is the exact type of comparison that I was hoping to see when i subscribed to your channel. I hope to see these keep coming. I also REALLY appreciate the links to skip to different sections. I would like if you were able to include these on all your future videos.

Something to note here. The AC being on most likely did not have any effect. I haven't tuned a new Camaro yet, but the 5th Gens and the new Corvettes as well as Chevy Cruze's and Silverados have a setting in the tune, that after either a certain RPM (varies but my 2011 Camaro was 4500RPM), or certain amount of throttle (varies but my 2011 Camaro was 90%) the AC compressor switches off. So knowing that when he went wide open on throttle on Dyno I'm 99.5% sure it switched it off. Great test btw, so overall i really think there was a decent bump in HP and TQ.

Thanks so much for investing your time to do this. And, thanks for saving me some money. Was seriously thinking about getting a CAI but not anymore. Thanks again!

Any chance that you can try the stock box with a high performance filter the next time you dyno?

Really well done Mat. Really surprising too. Oh well good sound, good look, and an extra pony or 2.

I don't even own a camaro. (13 challenger) buy your channel is pretty awesome and this intake test was very informative, I definitely was kinda shocked by the results. keep up the good work!

I am no expert, just giving my 2 cents worth. Also thank you for spending your time to do this for all of us Camaro fans. It is greatly appreciated! If the point of cold air intakes is to prevent engine heat from preheating the air that goes into the engine then wouldn't letting the engine cool before each run work against the cold air intakes? I would think that the engine would need to be hot already to see any gain from a cold air intake system. With a cold engine the air going in would be 97 degrees, if the engine was hot the air might be preheated to say 110, the cold air intake would supposedly prevent this preheating.

Great comparo ...now I'm rethinking some things. If the stock filter is even with the aftermarket intakes then I'm betting the K&N will knock it out of the park. I'm going to dyno my car this weekend so we'll see.

Still have my stock airbox thanks to you. Can't wait to see the Roto-Fab CAI results. I tried getting the GM CAI but they took it off of their accessories list at the dealership and I can't find it online anymore. I even gave them the part # 23408280. It's not available but the price is still there which is $525. I'll wait for your Roto-Fab video.

Dude you're awesome. Thank you for the video ticks. Subscribed.

Awesome man , now another test can be : drop in a K&N rectangular oiled filter( just the filter replacement) and the stock box , and with this we"ll se if just the filter give us more air flow= + HP , probably yes ? Probably no .

Great video man! Keep it coming!

I have never been sold on the idea of CAI increasing power and I think you just proved my point. However, I do run K&N drop in filters in the stock air box of my 2013 Camaro LS3. When you dyno'd the car with the stock box, was there a paper filter installed? If so, I would love to see the results of a stock air box run comparing a paper GM filter and a K&N drop in replacement filter. From my experience with the K&N, there is a performance sound difference that the cotton filter makes over the paper filter alone. Here is my theory on these CAI systems. I think that any power gain is due to the filter used and not necessarily the design of the air box. This is the most in depth video on cold air boxes on uTube. Great job!

Wow... Good video, shocking results. If like to see what BBK does as well.

Been waiting for this video!

Great video! As mentioned, the AC compressor disengages at WOT so the AC being on did not likely affect HP...especially not up in the top of the rpm range. Why does that shop not use an SAE correction factor? That would help mitigate the extreme temps for comparison purposes. Lastly, why does the car throw a puff of black smoke (fuel rich) at the top of the pulls? Is the AFR THAT rich or is something else going on? (Misfire).. Great job on the vid as usual....and saving all of your subscribers $400 on cold air intakes...lol

Great video man! Saved me some money :)

Thanks for the video. One less mod when I get my 6th gen

Great video well done

After tinkering with performance air filters in my sportbike and car, they do very little to no power improvements without a tune and better exhaust to back it up.

OK maybe I skipped to much and you said this but you have the aftermarket exhaust. Is that the duel mode? And what mode did you test in?

Surprising! I have the Cold Air Inductions CAI but have not tested...sounds great though. Isn't the GM CAI the same as Cold Air Induction's?

Sledgie, thanks for the time investment making this video!

I just look al KN website and they release an intake system , the blackhawk oil free filter , they claim 20 HP , the kit costs 363 , very interesting to see if there is real gain in the " performance intakes" ,

it takes a while for these ecu to relearn and adjust... idk seems like the ecu carried over learning.

stock intake worked better cause that's what the car is tuned to use. Changing parts without tuning the ecu isn't gonna give you gains.

Is the paper filter being used in the stock box? Also can you do a run with a dry flow drop in filter into the stock box to see what the results are?

I ran some Mishimoto stuff on my 2015 WRX and I was not impressed. First off, they are known for overstating gains in the Subaru community. Secondly I bought a $1000 intercooler from them and it fit like shit. I pulled all their stuff off, bought ETS products and never looked back. I would never run a Mishimoto product on my Camaro. I have an OEM GM z28 CAI on my 2015 1LE and I love it. Nothing better than stock fit and finish IMHO. 411

I thought a tune was needed to get anything out of a CAI or CAI/exhaust combo?

You have ported throttle body? Tried with stock throttle body?

sigh... what you have at 9:42 showing isnt a cold air intake, its a short ram, CAI's usually run straight down to the front of the car somewhere around the bottom of the bumper and are a problem when it rains because of hydro-locking being a problem :P Unless I cant see it and its directing straight air from outside the car in, its a short ram

curious to know your thoughts and the numbers on a stock intake with a kn filter replacement

Hey I just watch your vid great advice but I did notice that you had the tops of the C.A.I. Installed on your Dyno runs which is a restriction also you have a California car where the car is tuned extra lean to meet your states emissions laws (sucks ass) I think you maxed out your car with the ported throttle body and the exhaust system. You might get a little more out of it with headers as the car is, but you need a tune before you will see any more real gains and be able to take advantage of a C.A.I.

My engineering side is cringing every time he says ft-lb. It's lb-ft when you're talking about torque, ft-lb is a different unit of measurement.

this makes me sad, I was so wanting the mishimoto BUT o well. So I guess it's gonna be Rotofab or K an N.

I've always heard that the engine needs a tune before you see some real hp gains but I'm not a mechanic. One quick question, don't you need to tune the engine to be able to get those 10 hp gains?

I watched the whole video. Are you still going to be giving away one of these? I'm definitely not going to buy one anymore. Unless Gm still releases one with a tune. (which I don't think is going to happen anymore)

I usually run my intake with the lid off

Where does the stock intake, as well as the other two actually draw air in from?

i seen another youtuber get basically the same results when he put a cold air intake on a honda s2000 he dynod both stock and after market and it showed he lost hp and trq over stock intake i think that buying a cold air intake is just a wast of money on certain cars it seems that the factory got it right the first time

Have you considered a MSD Atomic Airforce Intake ?

I wish the roto fab Cai was out

So is GM gonna release their cai??!

Yo sledge, sorry f it's been said before but, do you have a snap chat?
