+brianmcg321 It's not about the ping pong balls alone. It's about proving that the K&N filter media flows more air freely per given airflow speed..What this translates to for an engine application is that for every throttle position, air will flow more freely into the combustion chambers, hence, less workload on the engine. Less engine work translates to better gas mileage, more power, more efficiency and easier acceleration.
I'm getting the ping-pong balls installed on my F250 super duty it helps the air filter : Pull in more air for my flux capacitor that I bought off an old crazy scientist
This actually does work. After installing in my car it began to idle around 250 RPM lower than with a paper filter. Idk bout horsepower gains but you can definitely tell the engine isn't working as hard to get air.
Joesus Trikes It works. The only problem I see is that eventually some of the oil on it is going to get released into the intake duct, air sensor, throttle body and inside the engine as well. I used to have a K&N drop in filter in my truck. It was there when I bought it. I took it out, because of the oil on the intake duct and the small buildup on the throttle body and throttle position sensor. I was able to clean the sensor and make it work for another month, but the throttle body required more frequent cleaning than with a regular filter. Cleaning the filter is a little annoying too. I kind of have mixed feelings for the filter.
I would strongly recommend the K&N Filter for any daily driver, well worth the money for many reasons. The longevity of a lifetime part with serviceable features, improved fuel efficiency, and a crisper sounding intake when cranking out higher Revs.
K&N are the biggest bullshit. filtering out almost no particels i mean its similar to no airfilter at all. Yeah a K&N Filter lasts longer than your engine
People always say "yeah the air flow is better, but does it FILTER..." Multiple oil sample analysis on this here RU-vid show that K&N filters work very well filtering particulates.
You people complaining are nuts. I have 300K miles on my jeep using a K&N filter and it still runs great! Even if it does absolutely nothing for performance (which I don't agree with), you will make your money back after the first few times you would have had to buy a paper filter. Not sure what is feeding the haters.
Wtf you guys plan on doing? Racing down gravel roads 24/7? The k & n catches dirt just fine. And 99% of the time your driving in somewhat clean air. I've had the same paper filter for 3 oil changes and it was still clean. But if you want better air flow and performance get the k&n. The point is, is that the k&n still filters out all the dust and dirt plus you get better air flow.
Most paper filters last a long time. My last one lasted 30,000 miles. These K&N filters will not give you better performance or gas mileage. A stock air filter lets more than enough air in an engine to make every ounce of hp that the manufacturer designed it to make.
***** Ok, if that's how you want to think. I was just throwing some ideas at you and my beliefs. No one said you had to believe them, but I would seriously doubt someone would take the time to come up with fake graphs like that.
***** If they are so great, then why don't manufacturers put them on their cars to begin with? Many race teams will even run no filters but their engines don't last but a few hours or runs down the track. If you are looking for durability and reliability, stock is the way to go. Run it the way the factory designed it. That's what I will do with my car. I have owned a K&N filter and the only difference was that it made more noise. Good luck.
firstly, More surface area= more flow. More pleats =more surface area. Try breathing through a piece of paper towel, then try breathing through a mildly wet cotton shirt. Which is more restrictive? you can say that the single piece of paper towel filters smaller particulates. That is correct, until you layer the cotton six times. Anyone who is bashing K and N needs to do some research about their construction. Another thing is that engines don't get more air, they get air easier, this reduces strain on the motor trying to suck in that air. That's where a slight increase in hp is seen but probably not felt. Better gas mileage is another benefit of this. Don't buy this filter for a performance boost, buy it to save money in the long run. 50k service intervals are pretty damn reasonable too.
Do you really think an engine strains any different between a paper air filter and a K&N? Think about it, a metal piston moving up and down creating a vacuum, that engine is going to get the air it wants no matter what filter is in the way. You need to do some research: www.nicoclub.com/archives/kn-vs-oem-filter.html Here's another link with some info from some guys that have worked in the auto industry for over 40 years: www.agcoauto.com/content/news/p2_articleid/164
I used to have on of these on my parts counter, you can see the entire circuit and there is no way to increase the fan speed. The flap on the back is to set and leave, based on your elevation (air density calibration)I promise, this is a legit test machine. only one button, on and off. and direct wires to 2 120v fans. both operate all the time. the fan speed change you hear, is due to less restriction on the motor of the fans by air pressure.Put a HVAC filter over your box fan to see what I mean
i think this product is pretty good cuz it can increasing fuel economy and improve acceleration more... but a little bit annoying is , the sound of your engine is louder coming from the K&N filter...
The other great bonus that K&N filters deliver is lots of dust entering the engine; it's awesome! Being a mechanic I service a lot of vehicles. I never see a clean intake tract with a K&N and never a dirty one with paper filters.
You are right Michael Kirk I've seen large mouse nests in filter housings along with dog food chokecherry pits and other junk, so no filter would be bad. K&N filters do work, just like the old oily filters on a Briggs and Stratton
People seem to be under the impression that this experiment shows more power. That's a common misconception that the only benefit is more air. The truth is the biggest benefit is easier air. Your engine works like a pump similar to that fan. The point of the experiment is the fan voltage/power consumption did not change but with the same power it can move the air easier ie the ping pong ball can now float or in the case of a car it can now accelerate/cruise the same using less power/gas.
But have you actually tried testing in the car on a dyno or one will lose apps The more air you lit into your car the more power you can make it may not give you a whole bunch it might give you two or three more horsepower but at least that's more
Put one on my Intruder and then had better MPG and more HP. Stock filter was about $25, the K&N was around $75. It has paid for itself many times by not having to buy more filters. I am installing one on my Ford Escape w/Eco Boost today. I'm curious to see how it works on it. Stock filter around $23 and K&N was $56. I will still save money and time. Highly recommended.
I put on in my truck today. Major difference. I will put these in everything I own now. And the mist of oil on the filters is what keeps the fine particles out.
To people who are saying "K&N filters allow more dirt to pass through" you need to put one on a car for 14 years like I have! When I changed my oil (every 5k miles), it wasn't dark brown or black...it looked the same as when I had the factory paper filter.
Steven Ray Uh, seriously? Air goes in the combustion chamber (air/fuel mixture). Oil is in the combustion chamber (on the cylinder walls). They make contact there. How did you think engine oil got dirty in the first place?
OddTimeMan Most debris that make it into the combustion chamber (as with oil) is going to be burned away, the only thing that would remain would be carbon, I bet if you took a bore scope you'd definitely see that in your cylinders.
DoomsdayMelody91 Not all debris gets burned away. Dirt won't get burned away. Heck, exhaust gases often include unburnt fuel, so even THAT doesn't always burn away.
I use it on my Toyota CHR 1,8 liters hybrid,the engine sound (at power mode and at max rev rate) and resonating vibration sound are more decrease with the K&N inbox filter than the oem paper filter.Car's sound improve like an atmosferic motors,vacum sound is better. Power and torque changins are not impressive,perhaps not.But I like it my car just now.
kn filters they are actually worth it.. i have 3 cars with kn filters... HP gains not so much but acceleration yes.. acceleration does improve becuase of the high air flow.. if you really want HP gains catback exhaust system including high flow headers... dont expect a lot of HP thoe ... true HP comes from forced induction such as Turbo or supercharging
hmm the video shows that the filter allows more air through per same unit surface area than the conventional paper air filter...its the closest thing you can get to running the engine without an airfilter without damaging the engine with dust particles seeping in..
My wife and I have mechanically identical 2013 Chevy Equinox's. I have a K&N air filter and she doesn't. I get 30 MPG driving in the country at 64 mph with cruise control active. My wife can't get more than 27. That is with 300hp V-6's rated at 24 MPG hi-way. I think I have a quicker car too.....but I have no data to back that up.
I even swapped the filter that came with the demo, for off the shelf K&N and and tried both FRAM and STP... I believe the application for the filter was mid 90's cavalier. try it yourself, or cross the filter # that's on the display unit filters. If you think it's fake, you just plain don't know how to use it.
OEM filter is the best when it comes to not allowing dirt into the motor. for the longest time while I was still on the stock EVO 9 turbo with a full turbo back exhaust and tune I ran the stock intake. the only reason I took the stock intake out was when I put a much larger aftermarket turbo on and had no choice.......let me tell you aftermarket cone filters do a horrible job at filtering.
You couldn't be any more wrong. Real world use as well as laboratory tests have proved it. I'm a mechanic and I've never seen a clean intake tract on a vehicle with a K&N or a dirty one with paper filters. I have a pile of K&Ns in the corner of my garage from all the vehicles I've switched back over.
@@royalclass23548 LOL, i used K&N filters in the past so i'm not "pro" or "against" but do a little research before writing this kind of things. Papers fitlers DO filter more.
@@royalclass23548 I've been performing flawlessly smoking 2 packs a day and drinking daily, must mean they're good for health. There's indisputable proof that your filter and my habits are both bad.
@@royalclass23548 And independent testing has proven that the K&N is the worst option. I'll believe those over a test done by the manufacturer who's motivated to show theirs is the best. My personal findings: every time I see a dusty intake tract there's a K&N in place. I have never seen a dusty intake from a paper filter. If the K&N is allowed to get dirty then oiled well it'll do ok, but there's a fine line between enough oil and too much.
@@royalclass23548 HAhahahah, no way. You sound like a salesperson for K&N, enjoy that. Here's an independent test using lab grade equipment, and there are others. nicoclub.com/archives/kn-vs-oem-filter.html
Totally specious assumptions: i.e. more air = more power? Why not just hook up a vacuum in reverse and blow air in? Decent regulation air filters are superior because they really FILTER fine particles that these glorified oil sponges cannot, and they are optimized by virtue of those many folds to equal large surface areas that do not restrict flow below threshold meaningful levels. K&Ns are like wet handkerchiefs for firefighters, versus real smoke inhalation masks. Paying extra for a lousy aftermarket gadget never represents any real savings and you may pay it back in engine repairs.
Kareem Baddar Exactly. These filters, much like Monster and even more pricey hyped stereo cabling paraphernalia, are great examples of marketing hype over solid science; once true believers bite, there is no way to convince them with evidence that they've been duped. Pity there is no such thing as false advertising regulation any more. Reminds me of the "Breatharian" years ago who claimed to live entirely on air, performing old carny feats of strength tricks until people started catching him eating 7-11 junk food.
yea, the reverse vacuum you speak of is exactly what they do ROFL. Its called a turbo or supercharger. A component mainly found in high performance cars and also airplanes
ive used nothing but kn filters for a long time if you lightly oil them they work perfect but ive seen people over oil 9 out of 10 so paper is the easy way to go be also more expensive
these filter have been proven in independent test to be ineffective. if you live in a dusty area you will wear out your engine faster. the filters yield more noise only no Hp gain
Is there a difference between the older K&N Filters and new ones? The old version on the box said 50% more air flow the new version didn't have that on the box.. seems like they took off all that marketing stuff
Ive had K and N filters on a car and my motorbike they make a louder sucking noise cost a lot more than a standard filter , seem to use more petrol and deficiently no more power ,Plus if they let more air through then stands to reason they must let more crap through ,I wouldn’t ever have another one in any of my cars or bikes .
I know their more air flo with k&n air filter but the job of a air filter is to block as much dust & crap going into our engine...my own opinion. I rather see a test result showing k&N filter gathers more dust then a standard air filter....
How about the dust holding capacity? If K&N Filter gives bigger airflow but less dust holding capacity means more air but poor filtration result and the dust will drawn into the combustion engine, have you proof the dust/dirt holding? It easy to proof it, weighed the brand new filter and weighed it again after a couple min/hours
+Muhammad Ikhwan I've been running K&N on all my vehicles for the last 20 years and I do all my own work on my cars. I've have yet to see a dirty intake from a filter not catching partials. The most build up I've seen in motors is the terrible PCV design most cars have. If you want a clean throttle body, intake and top of the motor get a catch can.
+Bryan Davis on all your vehicles huh, just how many have u gone through using k&n filters lol, to say u see no oil in your intake system after the filter is bs, your putting an oil soaked object in front of a vacuum and are saying none of that oil gets sucked into intake system making a mess, like I said bs. Plus your talking about putting a catch can on to prevent pcv oil from getting sucked into intake, yet you install a oily filter lol, so how many cars have u gone through in 20 years?
+Bryan Davis especially since u told that guy if he wants a clean " throttle body" considering the pcv is after the throttle body thus wouldn't get oil on it, the reason your seeing a oily throttle body is cause of your k&n not the pcv
more air flow means more dirt, dust and debris can get into your engine. the filter oil can damage maf in some cars. I'll stick with the factory air filter, it's not worth a few extra hp and mpg.
+XeDragHD that sounds about right lol. If we are talking about racing than you want to squeeze every extra pony possible. daily drivers it's just not worth it imo. a few hundred $$ for a few extra ponies isnt worth it, than again I'm pretty frugal
not always a good idea leaving an air filter out completely, i once was working on a vehicle just doing a standard service changing its filters and i found a dead bird in the air filter housing, imagine what would have happened if there was no filter? haha
People, as much as i love & support K&N Filters, for my car & for some of my friends and family, as other guys above have mentioned, this test is quite bogus. Still, i can't recommend K&N's enough over other after-market filters.
Quick question! Modern cars and bikes have o2 sensors. Sow does a high flow filter actually do anything on the basis that the ECU regulates the fuel with data comeing from the o2 sensor to achive a 14.7 stochiometric mixture dus practically maintaining the engines power? My opinion is to combine a exhaust, air filter and more important a ECU Mangement system that can take advantage of the parts. On its own its uselles i think!
+Bogdan Comanescu That's a common misconception that the only benefit is more air. The truth is the biggest benefit is easier air. Your engine works like a pump similar to that fan. The point of the experiment is the fan voltage/power consumption did not change but with the same power it can move the air easier ie the ping pong ball can now float or in the case of a car it can now accelerate the same using less power/gas. What a high flow system does in a motor is it reduces the power the engine needs to simply pump in air, reducing parasitic loss and freeing up power. It doesn't magically make power, it frees it up. Now if your vehicle can adjust for the additional air which many can (how do you think they work in high vs low elevations where air density is much different) you may make a little bit more power as well. A good intake will provide faster throttle response and a modest increase in engine output across the board. Now if you add a tune and a higher flow exhaust in the mix I've seen 15 hp+ on dyno runs going to a high flow intake vs stock (note: not just a drop in filter in your stock box) as well as much faster spool ups on turbos having less lag.
Paul McMahon I had a 99 Camry and I put a K&N panel filter inside. I felt a difference. Heck my mechanic drove it and said he felt a difference. I'm not quite sure how much of a difference you can feel in a new car, but in an older one you sure can. Just got a panel filter for my 2014 Sonata, about to test it out. 10-15 HP is quite a stretch to be honest, but not impossible. On average people see an increase of 5 HP. Now it may only be 5 HP on the high RPM range, but in the low RPM range you feel a difference like I did in my Camry. Very simple mod, easy to install, I would recommend for everyone. People trash-talk this filter because it uses an oil-based solution to trap some of the dust. They say that this solution could get to the MAF sensor and then the sensor will need to be cleaned after a while, but no biggie, just buy a can of MAF cleaner and that should fix it. Quite honestly, I don't think K&N would have a 1 million mile warranty for nothing...
Snoopy25 Warranty applies to the filter, not the engine. The filter will last, but the reason the engine has a restrictive air filter on it is to keep dirt and dust from getting into your engine via the intake. If you really want better flow, and don't care about filtering properties, just run your engine without an air filter.
Its very interesting that the car makers never thougt about this 😃. I get that it has better flow, but what about filtration? There is no chance that its near the oem filtration levels.
could you do a vid where you test them both fairly? i'm sure you'd get a ton of views since a lot of people would be interested in the result. just don't mention K&N by name so you don't get into any legal trouble. just say it's a popular aftermarket filter wink wink.
I live in Denver and the only time I feel a big difference in power is if I go to a city with lower elevation like Phoenix or LA. All these air filters do anyway is make your car sound meaner and that's about it.
Well, do I spend the money for a K&N air filter or not? If I get more air into the cylinder, the fuel injection system will compensate. But, if the oil in the K&N filter contaminates my Mass Air Flow sensor I could clean it. And, if it causes the sensor to die the new sensor would cost around $400- new and I could get a used one. Weighing the Pros and Cons, I will stick with the original equipment air filter. I would probably get too much oil on the filter after the first cleaning. Any other thoughts?
+JoeyPete Snider The oil getting in the MAF is true. Happened to me and I thought my transmission was slipping. Dealer advised it is the MAF and needs to be cleaned and advised me to use regular filters.
I had an olds 76 cutlass, 350, 4 barrel, not a high performance engine, would NEVER burn rubber, I put in a K&N, then it did, guess the few added horses got it over the hump? Just my experience, now all my cars have 1 in it, have used them for many, many years, just clean about every 15k miles and re-install, very easy.
What about oil build-up on the Mass Airflow Sensor from the filter throwing off the mixture because of the contamination and inaccurate readings? Why are K&N's charts on power gains only "estimated" when they have a dyno to actually run tests on and post real results?
I noticed a difference with throttle response in my HEMI. The reason everything is estimated is because every car is different. They cant dyno every car. And honestly an intake is a supporting mod it will not make a noticable difference on most cars. Modern cars have very advanced intakes from the factory withlow restriction. Some cars do better than others. In extreme cases an intake could give you 5-10hp but its rare. Most your going to get is throttle response and better fule economy if anything. I was lucky, but otheres see no difference.
JetKNINE ^Of course K&N is going to make a video deflecting the blame for bad MAF sensors! Truth is K&N filters will fuck up the MAF sensor with oil, I own 3 oil change shops and my guy's see it more often then you think...also it's been demonstrated time and time again that putting a K&N in makes absolutely no difference with performance or gas mileage, same with those "cold air intakes", also proven to be ineffective. Don't waste your money on a K&N filter, the engineer who designed the car wouldn't put in a paper filter if it wasn't sufficient.
JetKNINE I don't need to prove shit, the bottom line is K&N is a waste of money. Just look up the all the tests that have been done, time and time again it clearly shows they are ineffective and in some cases actually reduces performance. Most of you K&N fanboys only *think* ur car feels faster or more responsive because you blew $60 on a filter, it's the placebo effect at it's finest. Good marketing on K$$$N behalf, I don't blame them one bit...If I could sell snake oil I'd do it too. K&Fail
I bet you'd gain 10hp by budget modding a BMW stock airbox to fit and dump the cheap cone filter from your civic :D Meaning, the original BMW boxes have better flow than any of those cone filter models you can put in, and also suck some nice cold air in. Would be fun to have some cars to test on and make a video how it works in real life :) But yeah, if you want to change something, change the exhaust, if you want n/a power, headwork and cams.
Lots of debate in the comments. Just look at how they are made. OEM filter is made out of sheets of thin paper (like 1 ply toilet paper). K&N is made up of sheets of cotton. The cotton has bigger holes and relys on the oil to catch smaller particles. The real difference is in neglect. If you neglect to change a OEM filter, it will get clogged and suffocate your car causing problems with compression, fuel injection, precombustions, burning oil, and cat failure. If you fail to clean and reoil the K&N filter, it will cause damage to your engine before it will get clogged, sort of like a bypass. If it helps you decide, your oil filter also has a bypass. Either way should be find if you are not a dumbass.
You say the K&N filter will increase gas mileage; absolutely not correct. While it may increase air flow to the engine and maybe increase power by a microscopic amount, gas mileage has nothing to do with increased airflow. Fuel delivery to a modern engine is metered by computer, the more air going in, the more fuel delivered. If your air filter was 90% plugged, your gas mileage would not be any different but power would be greatly reduced. So, stop talking about gas mileage improvement, that just does not happen.
I'm not sure that's entirely correct. My average mpg went up by 2.4 mpg after about a week of having it in my 328i. Same driving style and conditions. My old filter was pretty dark tho. K&N didn't really make any notable difference in power or mpg in my Civic hybrid tho.
I stand by my statement. The mass airflow sensor does not know how dirty your air filter is, it just delivers fuel based on how much air is passing by. Your gas mileage may have improved, but it was not because of the k&n filter. Did you re-inflate your tires? A little extra air pressure in the tires might account for the improvement.
eu fiz o motor do meu gol e o mecanico me indicou colocar filtro de ar original por um tempo e depois posso ponhar filtro de ar esportivo mais isso arrebenta com o motor com o tempo isso e verdade ? esse filtro aí do video fica dentro da caixa de ar ? esse filtro não é igual aquele que fica fora da caixa de ar né
Get educated. that flap is "set and leave" to calibrate the air to barely move the ping pong ball, because at different elevations it has to be calibrated differently. Try it this way, put the paper filter in, set the flap so the ball barely moves. DONT MOVE THE FLAP, and switch to the K&N and the ball rises. That's the right way to use the machine, parts guy. and because you didn't move the flap between filters, it's obviously not the flap creating the extra flow.
I put a K&N filter in my 2016 Trax with 20,000 miles on it and the gas mileage dropped from 32-33 in the city to 26.5 mpg. I cleaned and oiled it as per the instructions. Will see if anything improves. If not it’s going in the trash. I’ll go back to NAPA paper filters.
More air flow? Sure. Better filtering properties? Sincerely doubt it. If you really want more horsepower and aren't too keen on filtering your air, you'd be better off running no filter since, you know, its free.
it is not as efficient as a Paper cellulose filter , as an Automotive Technician I am speaking from experiencem the oil in the filter can gum up your MAF sensor giving your poor air fuel mixture reading causing you to get poor gas mileage and in many cases wreck the maf sensor itself , another thing is the Pores are much much larger on K and N than OEM paper cellulose , this causes more dirt and debris to enter your engine contaminating your oil and causing premature wear.
More air does not increase fuel efficiency. more air equals more fuel needed for even combustion...and if this ratio isn't changed or becomes too severe running lean will make you burn MORE fuel...
i think the argument is because the k&n filters are oiled so this is what makes up for the catching dust and debris. coulr be wrong though idk i like k&n cause of the free stickers and they look better. Never really noticed a difference between paper vs k&n
Not always. Manufacturers use really cheap filters. Even a high quality paper one will work better. E.g. Cosworth's dry filters are tested to the same ISO standard and filter just as well, but let in more airflow due to having a much larger surface area. On an oil filter like K&N the oil catches the dirt rather than the filter itself. In the [very] old days cars used oil filters from the factory. But they are expensive and need maintenance, so manufacturers stopped using them.
