Deleting your resonator will NOT increase your power, in fact you'll LOSE power. Learn why ...

There is a myth that removing your intake resonator will increase your horsepower. This is a somewhat popular mod that's actually a huge mistake. You'll spend time and money and end up LOSING power. I'll show you what I'm talking about on my Hummer H3x (same as Chevy Colorado and GMC Canyon) but it applies to many modern cars.

You sir are absolutely 💯 % correct. People think removing it will make there truck sound louder and Removing it only changes the tone won't make your truck any louder. If you take it off you'll have the most annoying drone sound driving down the highway. No extra power removing it.

Thanks for foreseeing 3 years ago that I would need information on air intake resonators today. You must be a wizard! Yesterday (10 NOV 2023), I was delivering food to my mother, traveling down a 2-lane country road at around 50 mph, when a deer leaped out into the highway and slammed into an oncoming SUV, the first in a line of about 6 oncoming vehicles that were about 200 ft from me traveling toward me at roughly the same speed that I was going. The deer slammed into the side of the SUV, and careened off of the side of the vehicle at a downward angle moving toward me. I was driving a 1999 Honda Accord LX with a 2.3 liter VTEC engine. The deer flew toward me at a forward and downward angle so that it came toward me and went underneath my vehicle's front passenger side tire before I could get stopped--before the SUV got to me. As I ran over the deer, its legs apparently hit the intake air resonator and the fender well liner. Both were torn from the vehicle and became lodged between the bottom of the passenger side of the car and the pavement. The resonator was broken into pieces and the fender well liner was wrapped around those pieces. How the deer's legs got into a position to do that particular type of damage I don't know. It was a miracle that running over the deer didn't throw me into the path of the other oncoming vehicles. I noticed a difference in the sound of the vehicle when accelerating and when going uphill, but I thought that the deer had maybe done some damage to the exhaust system as well. Amazingly, there was no other damage to my vehicle, and the SUV wasn't even dented. I can't say as much for the poor deer. (I still don't know why it leapt from a safe place on the side of the road into 50 mph oncoming traffic.) Your video told me what I needed to know about the resonator's purpose and the disadvantages of driving the car without the intake resonator. Thank you for the informative video 3 years after you posted it.

[@Strider9655]

There's more to it than this, if this was the only technical reasoning (air air bouncing off valves), then the resonator would be on each branch of the inlet manifold and not before the throttle body. The resonator, or Helmholtz resonator, is atuned to a specific frequency (ie RPM), to remove specific undesirable noises from the intake system. The device may contain multiple chambers of different internal volumes, to act as multiple resonators. As an electronics engineer who spent 9 years in the audio industry, I can relate to this, on the electronics side they're like an RC filter network, they filter out specific resonant frequencies by storing and releasing energy at a rapid rate. On the speaker design side, the very same principles apply as to a car intake and exhaust system, every material and every assembly will have a frequency at which it will vibrate (resonance), the goal is to find that frequency and adjust that resonant frequency to beyond the hearing range (20hz to 20khz) so that it doesn't interfere with the audio quality. Take a 4 cylinder engine at 3k rpm, each piston is producing sound waves at a frequency of 50hz. If you play around with an online multuple tone generator and have some decent speakers on your PC, 20 to 50hz is actually physically uncomfortable at high decibels (it's that sound that churns up your insides), then when you add 3 more at 50hz you don't just get one sound, you get multples of the same frequency overlapping and creating harmonic frequencies, 50hz x 4, plus the harmonics, which can be pretty nasty, so your intake resonator is designed to suppress harmonic frequencies and reduce noise at 3000 rpm, to meet regulations for new vehicles. Why fitted? to meet international noise emission regulations for new vehicles, which is currently around 72db measured at 3k rpm. Should they be removed? Probably not Any advantage to removal? None, unless you like being an annoyance to others

[@luisz2853]

Thank you very much, I have the same car as you and I was thinking precisely about that, if by removing it I would gain power and sound due to having better air flow, now I know that it is not worth it and I will save myself the loss of time and effort, thank you very much!

[@domesticatedwolverine4152]

Excellent explanation! In the plumbing world it is called the water hammer effect. If a water line is closed too fast it will cause a water hammer bang on the valve face. The resonator works very similar to the arrestor in the way it absorbs pressure waves.

I say congratulatulations. this is a big help in understanding how "misterious" part of engines works.

[@betweenthepines4000]

A few aftermarket intake manufacturers are starting to “tune” resonators into their kits. AFE, Banks and Morimoto to state a few. Morimoto has even stated that intakes they made without resonators made less power than stock “Jeep JL 3.6 testing”. Very interesting and real engineering!

[@winha1435]

Wery good video about the subject. Thats why some tuners measure the lenght from intake to filter to match certain rpm, for many automotive makers noice canceling and emission/economy controll are more important than absolute peak power so resonator boxes are more matched to those recruiments.

[@flylowlevel817]

Should we wait for the dyno pulls to back up the no increased horsepower statement? Edited to add that torque increases can be a benefit, too, and while HP gains could be in a non-useful area of the curve, TQ would be useful.

[@germinationwide4life]

Great video. I'm curious about pre airbox resonators, such as the type in my 2012 honda accord ex v6. Some people delete it but at the cost of the cooler air that this part provides. I don't see it as being very restrictive, in fact, I would argue it is pulling air from the ideal location. Up high behind the grill but offset so not directly open to bugs or other debris. Also there are two slots built into the initial intake which allow water and heavier debris to pass through these points instead of being drawn through to the air filter. Modern engines are designed to be optimized as a complete system. If you change one thing it can affect nearly everything else. The computers are the unsung heroes of automobiles if you ask me. I'm amazed that some of these crazy new engines work at all. Kind of neat to follow the evolution in engineering since cars were invented.

Science disagrees with you

[@ephraimkaravan]

Every time i research intake resonators, i can never get an accurate answer to whether it hurts performance or not. The answers given by science nerds such as the one in this video make no sense. They say "the resonator has no interference with airflow whatsoever" then why the fuck does removing it hurt performance, if it truly doesnt interfere with airflow? Why do aftermarket cold air intakes, which don't have resonators, increase HP contrary to what the nerds are saying? Why do the legendary CT Engineering Ice Box intakes increase hp even though they are direct copies of stock intakes with a few modifications, one of which is removal of the resonator? And even if removing the resonator on a stock intake hurts hp, I'm sure it's negligible. And im even more sure that a tune would fix any loss immediately and give gains. I digress.

[@jdm_is350]

Great video, I wonder if that's the case for the resonator box directly under my air filter box tho? I mean couldn't the air just travel that short distance back to the outside?

[@kohanrains776]

My 04 durango has a resonator duct that goes over the top of the engine and it's only purpose is noise control and it increases intake temperature so it's gonna go the resonator in front of the throttle body can stay cause it's not heating air or at least not very much

[@rmedina1886]

Now I'm confused. I have a 09 base corvette. They come with a resonator, but the Z06 does not. I replaced mine with a Z06 resonator for an increase in sound. I didn't notice any lose of power.

[@ClaytonBridges]

this is really interesting. I used to have a Chevy cavalier that I did an exhaust and intake on, and it sounded absolutely terrible. the engine sounded good overall, but there was this horrid rasp, after tons of research Im very sure it was a resonance/frequency issue, I even had a resonator installed to help, didnt quite work. but it also had a K&N short ram intake on it, and after watching this video, Id be willing to bet the intake resonance vs the exhaust was making it sound weird.. on that note, I also had another theory, I live in CO, so we have reduced power, but also the piping wad 2.5" on a low power car.. and there was a theory that the exhaust gas was slowing down and also causing a weird noise

[@LynnDisclose]

What about resonator up under the car????

[@Cliffjumper]

My 1997 Acura CL 2.2 VTEC f22b1 has both a plastic intake resonator & a butterfly box style helmholz resonator. I have an open downpipe which feels and sound great... But I decided to keep the stock cold air intake system, and just add a K&N drop in filter.

[@lelenbates3367]

I tested removing the resonator on my Duramax diesel and I noticed decreased performance, so I replaced the resonator.

[@jacobrzeszewski6527]

Thanks for this video. I've known about this but wanted confirmation. I have a MK3 Focus and a common mod is putting on a partially open air box lid. But on the NA Focus the resonator actually makes really ugly harmonics through the rev range. So I just block it off with a pill bottle cap (since the open lid nullifies the resonator anyway). The only disadvantage is that it lost torque between 1250 and 1500 RPM. But oddly enough it didn't affect fuel economy at all. Just very low RPM performance. So I decided the sound was worth the torque. Running E85 actually had a more significant effect on performance for me.

[@Demoralized88]

Manufacturers willingly sacrifice mid-upper (thus, peak) power for increased low-mid torque all the time for improved 'driveability' to the average driver who doesn't care. In a lot of cases there's a big loss in peak power for a relatively small gain in torque (especially on recent-ish engines with very high flow potential, variable timing, etc.), though it's often the manifold runner design that does this and changing the intake can't change a whole lot beyond induction noise. In an NA engine, you basically have to choose between low-mid and high-rpm power unless you use dual-port variable manifolds (like Ford used in the 90s and 2000s, with others) that basically negate the problem. So, yeah I'm not surprised at your results and the Mk 2/3 Focus i4s are great engines that were known for good low-end and decent power which makes me suspect it's less in the manifold and more in the intake/exhaust design. Great cars with the Manual

[@jonb7911]

Hey cliff, now we know that the main reason the intake resonator helps disipate the pressure compressions coming back from the valves, why are resonators on turbo cars? The resonator should never see the pulses from the valves, but only from the turbo. Could you talk on that please?

[@brickswisher7672]

If the intake resonator is pre air box, would sound reduction be the only effect? It seems like the air box it self would dissipate the pressure waves.

Nice Video, Would you get better airflow by replacing the corrugated flex joint on the intake with a equal diameter piece of silicone hose that is smoother on the inside?

[@CliffsGarage]

Theoretically, but it depends on the size of the conductor. Turbulence restricts airflow, but is mainly near the inside surface while the airflow in the middle is smooth. The larger the tube, the lower percentage of the airflow is affected. I think the intake is large enough that the corrugations don't really make a significant difference.

Coincidence it stopped right behind the mechanic's shop and i asked them how were they going to get it to the shop. he said we use starting fluid. so 1 man must be walking outside with hood up and 1 driving to the shop stall. be careful with starter fluid cost me 130. diagnostic 20. of epoxy for temp use and i quess i need to order one for 65. 9. uber ride starter fluid backfire cost me 214.00 so far and lots of time, but i am thankful for mechanics diagnostic of and learning about this resonator. this is my first time using starter fluid just thankful it didnt blow up my intake manifold which is also polymer material. 1 backfire is all it takes to blow it up. thinkin bout just put 1.5 inch 90 pvc elbow and a 12 inch pc capped seems about the same size and it doesn't have seams it would never break or blow up again.

[@honeybadgerwrx]

I really appreciate the informative breakdown of it all. But the question arises. If this is true as I believe it to be, why do all aftermarket intake systems not incorporate something like this? Additionally does having a turbo charged 4 cylinder made the need for the resonator greater or less?

[@supermarioisacat]

Most people want aftermarket because of lower weight and or reduced clutter/complexity. But unfortunately, many "intakes" draw hot air from behind the radiator, near a catalytic or from some other non-optimal location, offsetting any potential advantage. Many of those who remove their OEM intake regret it when they notice flat spots, loss of mid-range torque and possibly a general loss of power. For forced induction (turbo/super charging) many systems are required to have a resonator on the compressor inlet, but for an entirely different purpose: to help muffle it's shrill whine/whistle.

[@hashishsenju2015]

What I'm wondering is how much does a resonator actually help in dissipating the back pressure. Or can a straight cold air intake shove more air into the engine to compensate any back pressure or turbulence loss. I mean just look at a supercharger

[@The_Slippery_Slope_NZ]

Air intakes don't "shove" anything, a turbo would do that. Air intakes are just like the hose on a vacuum cleaner.

[@winha1435]

it depends your pipe lenght and how well it matches whit intake wave lenght on certain rpm, effect is called dymanic chargin or hemholts resonace charcingn its used in intake tuning but can be used to for smaller effect on the pipe from intake to filter aswell.

[@esnevip]

[@happygnome4620]

Im assuming this is not applicable in a turbo diesel application, that backpressure would be so negligible after being compressed by the turbo.

[@dmonpnda4284]

So I hear a lot of conflicting opinions on this with no scientific proof; I’d love to see a video of an intake system with a vacuum gauge showing the difference in resistance. As shown with your intake a pass through resonator system but with vehicles like mine that has a snake through resonator system. I would like to see the differences.

[@9jfd1]

So can i ADD an intake resonator? Currently running a Jeep XJ with a '92 I6 4.0HO engine. I'm using the K&N cold-air intake, it looks like it kinda has a ballooned res over the TB, where the air collects before entering the manifold. I guess my Q is, can i just jerry something like a pvc tube to another small compartment in hopes that it becomes a resonator or would that potentially mess up my intake process?

[@Sarahndipity96]

Could you not just adapt the factory resonator from the last gen 4.0 used in the TJs, WJs, and later model XJs?

[@Cheeky-Biscuit]

My stock snorkel has a molded resonator attached to itself and this fits to the air box (2006 focus) so I ask myself do I suck my air from my wheel arch or deal with back pressure in the intake

[@supermarioisacat]

A bit more detail: Resonance implies oscillation/vibration. Intake resonators are designed so that pressure waves created from closed intake valves travelling out the intake tract get "stored" and are reflected back into the engine, arriving just as the valves re-open (within a specific, narrow RPM range). This packs more fresh air into the cylinders than would otherwise be possible (mild supercharging effect). The intake of a modern engine is literally tuned like a musical instrument so that the effect occurs near an RPM most beneficial for that engine. The sound you get by blowing air across the top of an empty bottle is a good demonstration of the concept.

[@glowiever]

I could hear my motorcycle's airbox humming at certain rpm. is it normal? I think it was the rpm where the engine was at its peak power.

[@supermarioisacat]

@@glowiever You must have good ears to be able to notice a motorcycle airbox resonating at peak power above all the other noises going on. As long as it was just a "hum" I wouldn't think much of it.

[@glowiever]

@@supermarioisacat my motorcycle setup was optimized to reduce noise as much as possible. I love silent motorcycle. other than spraying injector sound and valves being tapped, my motorcycle is pretty silent and healthy. I could hear the loud humming sound, exactly like someone blowing over a bottle head, except it's deeper (had more bass), kinda freaked me out when I was riding fast thru the dark, rural road lol. it had a certain ghastly "boo"-ing sound to it. but it only happen in certain narrow range rpm, around 6000-7000 rpm-ish I guess. It also felt like the bike had extra "push" when that happens, so I'm happy.

[@supermarioisacat]

[@Lss1six962]

I understand this argument and it maybe true for turbo applications giving a larger volume of air for spool up. But the main reason they did this from the factory was so they didn't have customers coming into the dealerships complaining about engine noise. Like some comments aftermarket intakes do not this resonator; and most aftermarket intakes are not true cold air intakes. These are both true. The factory intake on most vehicles are already cold air intakes. The resonator takes up air volume and in turn noise because it is canceling the intake pulses with volume. But that resonator is also inside the engine bay being heat soaked. That volume of air inside is also heat soaked. When the engine calls for full throttle (your foot) it is pulling that heat soaked air into the engine as well as the colder air from the air box. The air inside the resonator is already at a lower pressure because it has already passed through the air filter (restriction) so it becomes the first air to enter the engine. Exhaust pulses are true and very important after combustion; especially on 2 stroke engines with wild expansion pipes to help/need scavenging. In a 4 stroke a resonator will cancel out exhaust pulses (tuned to correct length) and reduce drone and in turn sound and not effect exhaust flow much. That pressure pulse from an intake valve closing will bounce to the next cylinder on the next cylinder on the intake stroke. The resonator is just soaking up this pressure wave with volume. No race car/ performance car or truck is designed with an intake resonator. I'm not trying to argue with you sir just trying to give a different point of view.

[@maxparker5199]

Not true, a correct cold air intake increased my horsepower of my Acura TL by 6 horsepower. The trick was getting wider intake pipes, positioning the intake by the original airflow inlet on the bumper, and just overall making sure air is flowing from outside by getting measurements and cutting pipes correctly. Also you can add heat tape near the throttle body part of intake to moderately decrease the heat of pipes

[@maxparker5199]

Granted it was only 6 horsepower on the dyno, but it was hotter that day so it might be more. Also it might not be worth it. I spent 120$ total. However both low end and high end increased and throttle response. So if you’re willing to put in time, it can work

I was talking about the $500-900 off the self kits, with open cone filters with some "shields and rubber gaskets to seal to the hood" Anyways... Currently in process of 3D printing the finished parts now in high temp ASA. The OEM intake horn/snout that bends to a 70 degree bend to the inner fender BUT with the fender inner liner it has no real fresh cool air to draw from. Pulled it out and cut it right at the flange to mount into the air box, so I still have the OEM seal to the box. Route it forward through the 4" gap between the radiator and the Rad support. Kind of how the Hellcat head light intake port is. Printed it with a minor smooth bed to avoid any water dirt etc and added a hexagon screen design to the flared for extra protection. My intake temp was 120-135 (under hood pulling from the fender) I'll have to see what it is once it's finished.

Yeah I talked to a GM engineer about my Duramax, he said they are useless. I took mine off. My turbo did spool faster and did have a more distinct turbo sound. It’s not substantial, but it’s there. No there is no power increase, that I can feel, just some sound difference. Cleans up the engine bay as well. Do what you want, but it want hurt your truck’s performance what so ever. Banks even makes a delete for the L5P. Banks it’s all about performance, if it hurt it they wouldn’t make it. Just my 2 cents.

[@cobravids]

Sir, let me first thank you for confirming what my beliefs are. I'll start by saying this, I purchased a Roush cold air intake for my 21' Mustang GT. Once I pulled all the parts out, I immediately noticed a large port was missing off the 90deg piece coming from the intake. I questioned the seller, and he referred me to some literature that instructed me to delete the resonator to install this CAK. I immediately thought this guy was insane. I always believe that engineers go to school for many years for their degrees, they are much smarter about the card they designed than most "mechanics" are even in so-called performance shops. I will not delete any part designed to achieve the highest level of performance from the factory. They know what works. MY QUESTION TO YOU (I hope you get this). There is a spot on the new 90deg elbow that I could easily drill and add the resonator tube to the new part. In your opinion, will this operate the same? Or should I stick with stock? The only real reason I want the CAK is for the look of it. It has a see through window to see the filter.

[@CliffsGarage]

I'd say it's highly unlikely that adding the resonator in that position would work as intended. As you say, it was engineered specifically for that car in the stock position.

[@cobravids]

@Cliff's Garage That's what I was thinking too. Thank you for taking time to respond. I loved your video. You obviously know what your talking about. It's being sent back. Keep up the good work and spread the word. Cold air intakes should not be deleted.

[@hulkhatepunybanner]

*This explanation lines up with Cycle World Kevin Cameron's November 16, 2018 video on the same subject.* According to him, a resonant air box can boost torque by 10%.

[@CliffsGarage]

Really, I'll have to look that up and see if he says anything I missed. I got most of my info from an automotive engineer who spent 15+ years doing nothing but intake system design.

[@TennisWorldSetPoint]

First time i def messed up and theew out these two plastic tubes of you buy the cold air intakes there rubber tubes that kead to it i think to get cold air into the head. But they had to use platic tubes to connect everything eith the takaeda cold aur intake. Im worried can oil get up in my intake on my g37? I would email u a picture abd may e you can met me kniw uf im ok or not.

[@kenshin034]

Correct delete the muffler not the resonator If it’s legal to do in your state

[@eccentricsmithy2746]

So how come I gained 10hp on the dyno by just adding a cold air intake that deletes the resonator?

[@CliffsGarage]

Well, the thing is that you _didn't_ just delete the resonator. You changed a major part of the intake system. It's quite likely that if you had left the resonator, you would have gained even more.

[@lilfendiiofficialpage]

I have a 14 c300 sport it has an intake resonator but it’s very small. I wanted to put an after market intake on my car, I was wondering if I take off the stock intake and it’s resonator will I still lose power or will I gain power because of the better intake?

[@Demoralized88]

Factory intakes are designed tor low-mid power and efficiency, which necessarily hurts peak power. In most cases, if the major restriction isn't the actual intake manifold runners, aftermarket intakes sometimes give mid-high RPM power gains but also may hurt low-RPM torque. Depends entirely on the engine but worst case is small loss of low-end with mid and upper power unaffected.

[@coreyhoward8950]

I just stopped the video at 1:32 because the resonator delete that people are talking about is apart of the exhaust, not the air intake.

[@CliffsGarage]

Not true

[@Demoralized88]

I had a 2012 V6 Mustang and did a lot of mods, you have something wrong with that big of an RPM drop from an alleged resonator delete. Are you talking about the H/X pipe that deletes the Cats? If not, and I don't know the 15+ chassis, you probably have either a big exhaust leak from a bad install or, less plausibly, the tubing is just SO oversized that it completely killed your low-rpm/low-throttle power which is definitely an issue with some exhausts. My 3.7 had the Dynomax catback with I think 2.25 tubing and BBK short headers which didn't hurt my MPG and low-end much, but long-tubes headers especially with oversized exhausts were known for losing a ton of low-mid torque. You should probably have engine codes with that big of a difference

[@locklear308]

Never heard of an intake resonator. Is this the same as the intake silencer?

[@user-jw2fp5mq9p]

I have a 2007 H3 here lately a few times when I start the engine, it shakes and sounds horrible and every light on the dash comes on traction , low power u name it every light. I turn off and on let it sit and a few times later it all good. Can u guide me where to start first with fixing.

[@Demoralized88]

Sounds like a bad ground strap or other big power connection. Nothing else is gonna cause multiple independent systems to fail at once and this is also common on GMs with underbody rust/rot.

[@drrightwing4435]

No prep cars do not have resonators and their hp is not affected, obviously. Resonators affect only throttle response. However, in high rpm, in high performance engines with tunable or aftermarket ECU’s, you want a higher compressed intake/intake charge that the ECU can use to increase air/fuel ratio, This is why race motors, N/A or forced induction ones, do not use intake resonators

[@michaelturner7641]

Well said sir fortunately my 46-year-old brain can understand it.

[@emsea7279]

Only for noise. Makes less power for sure

[@goorasan]

And what if resonator chamber is on the very beginning of intake before air filter? You can find that in Honda K24 engine for example. Can you explain? Very good video BTW.

[@ryaandnice]

Same Q!!

[@NightWalkerasd]

That would be nice to know!

[@MrScoobieman]

Dropping in a k&N air filter, will that improve anything?

[@msg63bretired82]

An engineer once told me a piston doesn’t “pull” in air. Rather it creates a vacuum and the air flows in when the valve opens. 🤷‍♂️

[@Stuckofftherealness]

Maybe on a gasser but not a diesel.

[@andrewgibb9782]

does this apply to every single car because i deleted mine without problems and it feels more responsive

[@Dannytc559]

Mine as well. Basically, less restrictions = more flow which in turn = more power.
