- Prices have changed since I did this video, BUT
Here's the one I have, amzn.to/2nucwbL Compared to the K&N filter amzn.to/2numdqp
The K&N and OEM stock motorcycle air filters are different. "High performance" air filters from K&N won't make a difference in performance, like they are boasted; if anything, it's high-flow design will simply let more dust and debris into the bike's engine. In this comparison video, I explain the benefits and the bad between the two.
How to install and oil your air filter (Yamaha FZ6): • How to Change and Oil ... - ยานยนต์และพาหนะ
I've been running K&N for over 30+ years and have not purchased a replacement OEM paper filter during that time. Put 200K on my Porsche K&N, 15 years on my KLR 650 and every other car and motorcycle I've owned. K&N filters are the absolute best when properly maintained, but obviously these air filters are not for everyone as it requires some intelligence to maintain them.
I would tend to think over that length of time the filter you have has degraded to a point it isnt filtering 100% anymore, with even a little bit of nous anyone would know that. The video topic is valid 😀
@@jeffestrada6857 Paper filters degrade over time, K&N filters will not degrade over tine when properly maintened and serviced. Clearly you don't understand how the K&N filter works.
A very polite way of saying K&N filters are labor intensive for little gains. You shouldn't have to maintain a filter, you replace it.
@@broderp labor intensive? You literally don't need to do anything for 50k miles and have a more efficient air flow the entire life of the K&N. Not only less labor intensive but less expensive over the life of the vehicle. Use whatever filter you want but don't make ridiculous comments to support your incorrect theories .
Little gains,? As opposed to what, negative gains.?
I have literally gone 80k miles on an original K&N before recharging it with no loss of mpg or power over that time.
A lot less labor intensive than driving to the parts store, buying an inefficient paper filter, and replacing it 4 times genius.
It was a polite way of saying the not so intelligent should use paper filter because simple instructions are too complicated to follow.
I'm gonna switch to a K&N filter by August! I can read all day the back and forth debate over OEM or aftermarket but if I'm ever gonna learn or test anything new sooner, it's gonna be now on my tiny starter bike.
A filter is a minimal upgrade, depending of course on the quality of stock. You want performance...up the cylinder volume, port and polish. Get a hp cam and retune.
was hoping for something more than an opinion, like a dyno-test maybe. in my experience, most OEM parts are made down to a cost to keep the bike/car/truck/whatever manufacturing cost down to an affordable level, compromises have to be made.
A filter is so cheap. If it has made discernible difference (bolt-on 5-6 HP), the manufacturer would have used it. Tests were performed on the K&N filter vs. others and the result is that they restrict less airflow at the cost of letting more particles in. Whether more airflow would produce more power is bike's specific, and in any case would depends on you modifying the entire system (read: $$$) for performance to be noticeable.
In accurate considering in the eu bikes have to be restricted and most common way is to restrict air and feul and going with a worse flow filter makes it hold those rule sets@@dinhdatVN
I agree with you, I’ve had them all and I believe the OEM is best (including oil filters) however what about the Sprint air filter where it can be easily cleaned without oil and reinstalled? I suppose the fact they are so expensive once again just using the standard air filter makes sense. I must emphasise we are talking street bikes with no modifications 😀
In the 90's i remember a dyno shootout for 14-inch round automotive air filters. Paper element purolator filter was by FAR the best bang for the buck. I believe it was under $5 while the k&n was around $40 back then. I believe the purolator paper was about a half horsepower difference on a 300 hp engine. Sure the k&n offers longevity but i always wondered how well they flowed after being cleaned and oiled versus a bran new K&N? That difference alone could be drop off a half horsepower.
rapidride2 thanks for the comment!
Less throttle lag on mine with a K&N. So its not just about the HP.
Fun with downshifting ;)
I fitted a K&N on my Street Triple a few months ago. You're correct I noticed better throttle response. I have just got to my first clean/re-oil
the real dill behind it is supposed to be the improvement at the high end of the torque curve to keep it from dropping at the high RPM
it's not even that, it's that high flow air filters put less strain on the engine, less load as the air is pulled more easily, so you can (and there are videos proving it) gain a small amount of horsepower
Check DNA filters. It's a greek company ad they give life time guarantee and also are clearers that it enhances the engine power.
"Why would Yamaha design an air filter that wouldn't give you good performance in the first place?"
Because performance isn't the only thing they're designing for. They need to color within the lines. In other words, they have to meet EPA emissions requirements that grow more and more stringent every year. That's why your factory air filter and factory exhaust pipe aren't meant for performance. I'll be covering this in my video this week if you're interested.
Well... I just installed a K&n air filter and yes big difference, of course I had to RE jet the carbs, it feels more responsive and incresed power.....
What do you mean RE jet the carbs?
He means changing the fuel jet sizes in his carburettor so he can get more fuel with the increased air intake from the air filter. Otherwise hed be running it lean
@@coencleland1025 so by me increasing air intake only doesn't help without the fuel increase.
Franklin Hornet youll get a little bit more power but you will be starving the engine of fuel which does make the engine run hotter and may burn internals in the long run, to make it 100% safe id put bigger jets in and put an aftermarket exhaust on to see the most power increase. Dont need to worry about hurting your engine unless you thrash the shit out of it constantly or take it to the track. But too much fuel will leave carbon deposits. Hope that helps
@@coencleland1025 Thanks for that
Much appreciated
After putting on a new full exhaust system my bike began running rich. So I put a high airflow filter on it and now it has the right air to fuel ratio.
No tuning or adjustments? Runs perfect no pops?
@@rider6.0 im not getting any pops. But I doubt its running to the best of its abilities. I would need to get it on the dyno for that
Full exhaust causes your bike tou run lean not rich due to back pressure decrease,a high flow airfilter should make it run even leaner
i have an acropovic full exhaust system installed. what should I do with air filter and the tuning?
@@metalmoto3275 I know right? I have short shots, a k&n and a PC and still get decel pops lol
The only thing I will say about them is not the horsepower it’s the overall smoothness of the bike. Both my gsxr and gsxs have changed drastically for the better in throttle response. Gets rid of the snappy jolt when applying subtle throttle. Also gsxs rpm gauge would flicker as it puttered around in a 10-15min warmup. Swapped filters and the bike idled quietly with no putter or flicker and was ready to go way sooner.
I got the gsxs750 and am contemplating getting the K&N filter as Well because of the annoying snatchy throttle respons… it really helps with that?
@@betweenframesproduction3968 I still have my Gsxs750 today. Marks about the 2 year mark with 10,000 miles. Still smooth as the day I put on the filter. But, Be prepared for an extensive break down of the bike. You will have to take off all the front fairings to access the air box to install the filter. Ultimately, You will get used to the bike and the throttle response so I wouldn't worry about it too much if you don't want to mess with the bike.
It wasn't a make or break on performance for the bike as much as the GSXR. Make sure to turn off all traction control options once you get used to the bike. It will stutter off the line because it's trying to reduce wheel spin which in all reality is more annoying than anything as it won't slip a wheel. So mode status should show "OFF" on the right side of your instrument cluster. Think they come in mode 3 by default from factory (Rain mode)
The bike is one of the higher rated Torque Naked motorcycles so she will be snatchy on throttle by default. Just take your time and the bike will become second nature. Still love the bike till this day with no complaints or issues.
I must agree with almost all of the comments from the people who replied... this video is without any actual dyno proof. I have years of actual dyno experience and I have seen gains of anywhere from2 hp to 5 hp with use of K&N air filters... and that is over a range of rpms . Your opinion is one thing but the truth is a factory oem filter is made to a low price point to meet MINIMUM specs... K&N filters WORK!
I upgraded the filter on my Ducati because the factory filters are $85 each and I need two of them. The performance filter was $100 bucks and it's lifetime.
However, I immediately noticed a difference! Better fuel economy, and better power.
thanks for this video but is the best KN or the original,oem???
it will do something ,but you have free up your exhaust frist and tune it to give it more fuel and it depends on how restrictive your stock filter setup is that's why they make no clams.
I thought K&N was a bunch of B.S. until one day I noticed a difference. I have one on my Harley and don’t notice it because the motors been all done up. But, I have two Honda monkey’s both with just Yoshimura pipes. One has K&N filter one does not. I’ve been riding the one with out the K&N and one day I jumped on the one with the K&N and notice better throttle response. Did it give me more hp probably not just responses better and I notice it as I’m riding
Does it affect the sound in some way?
Thank you for the great video. I purchased a 2009 Kawasaki 1700 Vulcan Nomad and took the K&N oil filter out and replaced it with the original stock oil filter. When I had the v twin flushed, the technician said to stick with the original parts because in the long run the K&N Oil Filters recirculate the old oil inside and damages the engines. Motorcycle Mall in New Jersey, they said they had quite a few engine rebuilds do to K&N oil filters.
K&N does flow more air. A motorcycle magazine back in the 1980s did a shoot out and K&N gave up to 0.25hp increase over the stock paper air filter. The stock air filter on the Kawasaki Ninja H2 SX SE has a pleated design, basically copying K&N. The stock air filter on my ZX9R is double wall foam, which detiorates over time. It was missing a corner piece when I replaced it with a K&N. I noticed K&N spreads the power out like a V4 compared to stock, which concentrates the power on the top end. Also better throttle response. Both with stock 49-state titanium exhaust and a Micron carbon fiber competition slip-on (with no baffle). Also I run K&N with a Toomey airbox on my Yamaha TZR250. Beet Japan exhaust, Hy-Tech reeds, extrude honed cylinders and carbs, milled head, welded crank, lighten con rods, etc. Stock or modified, K&N does the job.
Yeah, it sure does! But for a stock bike, it won't give you incredible (or noticeable) gain in power and has no impact on reliability of the bike long term.
@@TheInja I have 78K miles on my ZX9R, 95K+ km on my TZR250, currently 263cc now. K&N improvement more noticeable on a two-stroke. Have passed many bigger bikes with my TZR.
Actually a stock Harley iron 1200 air filter is almost $28 and is made with paper not fiber and it is quite thin. The K&N replacement filter is hands down better quality just looking at them side by side. It costs almost twice as much at $54 but is reusable so after the 1st use you're even. The K&N is obviously going to provide better airflow than the thinner stock paper model. Does this transfer to more horsepower? I would say not but for my money I go with the K&N.
Hi bro, thanks for the video. just one question. I just have a simple yamaha 125cc but i want to change the oem stock filter for a k&n filter do i have to change sth in the bore as u mentioned in the video??... thanks....
Victor Sepulveda I mean you don't have to. for a 125cc, I don't think it will make any significant difference. if you do a big-bore kit, a KN filter would be great!
Hold a K & N filter up to the light you can practically see through it. If it flows more air, then common sense tells me it flows more dirt too. I used them years ago, but never again.
Yeah but the engine will use the same amount of air no matter what filter is in there. Or none at all.
I just hiflo makes air filters too, for like $20! I'm gonna try that :)
Basically it’s not worth changing the stock filter unless you use a race filter and remap your fuel system to make the most of it.
Map Hump eeeexactly. 👊
Went with bmc filter not fan k&n on cars and trucks. Performance idk made different but you can hear air intake when riding it fast and exhaust sounds deeper.
Some of this really is inaccurate. While i'm not a fan of K&N air fiters @0:58 you say "wether its a high flow or not your going to be taking in the exact same amount of air" Thats just plain wrong. A lot of bikes today have some form of ram air so the air is being forced through the filter when the bike is moving. A high flow filter will allow the air to flow easier though the filter meaning more air will get though since its as restricted. You also talk about bike manufacture designing an air filter to not give you good performance, the bike maker actually designed the stock filter to be quite restrictive it's done though the filter and airbox sometimes. They have to deal with EPA and EURO regulations K&N does not. Honda, Kawasaki, Suzuki etc etc. have to make the bike work with in emissions regulations for the entire RPM range. Somethings to think about.
Donovan Lewis While you're right, I wasn't necessarily wrong. what I meant by that is the engine has to combust using a specific amount of air on each stroke. while the air with a stock filter while restrict airflow and work harder for the air, it will be using the same amount of air.
and yes, I understand they work with emissions regulations. and if you're going to put performance parts on your bike and tune it, a high-flow will help. I have experience with that. for a stock system, a stock air filter will work best is all I'm saying. all the K&N will do is let more contaminants in on a stock/mostly stock system.
Donovan Lewis The bottom line of this video is that no, you won't gain horsepower and torque if you have a mostly stock bike (which pretty much every rider has on the streets, we are excluding racing communities) and just stick a KN filter in it.
@MotoPaisano I just got a 2008 low miles FZ1. What did you do cuz iam scratching my head. Iam looking for exhaust and air filters like crazy bro?
I have had a k&n filter for 15 years washed it over a 100 time and it still looks brand new plus it does let air come through easier causing a horsepower gain
What it looks like and what its doing internally after breakdown of material over time is debatable
No gain without a tune. Getting more power is determined by the CORRECT A/F ratio. Adding more of one or the other is'nt giving any more power.
The engine will use the same amount of air even if you remove the filter entirely.
Something I should add to this video is that if you have performance mods and a custom tune on your bike, a high-flow filter will make a big difference. Just did a bunch of performance mods to my car and added a high-flow (cold air) intake which definitely helped with performance. But this video is just to say you won't get any more performance with your bike if you just stick a new air filter on a stock bike.
The years of use out of a stock air filter? I change mine every season small price to pay for a 10 grand bike i have.
@@kawilifezx10r23 th-cam.com/video/WixTvlFvOlA/w-d-xo.html
Man I’ve just cancelled my k&n filter order
I think you’ve made good point since they are not saying specifically that it is tested and verified
Yeah unless you have heavy engine modifications, a K&N won't do much.
hey man, nice vid, , i mean that filter actually it does help to make the bike/car breath alot better, its like covering ur face with a blanket you will be breathing much less, yes you are right, people go and just buy this thinking that they will get hp but they wont, you do not have to get the engine out to get more hp or performance, just with a chip is necessary, a motorcycle or car or whatever, it has a computer, which it's set to get things till certain points, so if you put a kn filter x pipes exhaust, basically u go full exhaust you will not get anything till you really reprogram your ecu to get the most of it, to much overflow will need a tuner to let the computer know that you got something better and different than stock
Balto The Husky's Adventures yes, and that's a tangent. this video just says you can't simply drop an air filter in and get better track scores. haha
I have vehicles modded and tuned, and high-low filters make a HUGE difference. but KN and people online say that the AIR FILTER gives you more HP and torque, when really it's a tune and performance intake PLUS a high-flow filter.
I have a 09 zx10r was thinking about ordering a bmc airfilter, block off plates, cat delete to a 3/4 exhaust and a power command.....Will the bmc not be needed and just stick with stock?
It will help if you're doing performance mods!
High performance filters do not make any earth shattering difference to the performance of the vehicle. I have had this tested on dynos using the stricktest guidelines. The difference is that with hours of use, the paper filter will drop performance much faster than the performance filter. That's it. So either you clean and replace your OEM filter regularly or drop a performance filter and let it ride; but performance filters need cleaning too, only the cleaning interval is longer.
What you are saying is that the OEM filter gathers more smaller particles and gets clogged while a high performance filter lets more shit into the engine and therefore does not get clogged. Or maybe the particles magically disappear to some other dimension with the performance filter :-)
@@N0t4v41l4ble u do know foam (aka high performance filters) were made by a guy that drived 24 7 through a desert. he made them cause the OEM paper filters would still let more dust particles through than one that is foam and oil based. apparantly doing just talking rubbish is a hobby of yours
I am getting a Nibbi Carb and they make their own air filters. Would it make sense to get their filter for their Carb? I don't know much about Nibbi but all the reviews I read were positive. Do you know much about them? Any input is appreciated.
I'm sure they're fine. Most sellers buy the same parts from the same manufacturers just with different branding, so chances are they are as good as the competition. But again, never personally used them.
Maybe for expensive motorcycles, but here in Argentina, almost all the motocycles with a reasonable price are chinese, with 15x15 cm paper air filters for 150cc with 28mm admission (i have a Corven Triax 150 R2, and this is my case), wich costs 1.5 dollars. In these scenarios the air filter is a limiting factor at mid/hich RPMs, as the piston needs to pull really hard to suck air into the chamber.
I'm telling you that in these motorcycles, wich cost less than 1,000 dollars (normal income here is 200 dollars), the difference is really noticeable.
The only way to check this properly is to run the same vehicles in the same environment, for the same period, and then perform an oil analysis of particles in the oil. I'm sure it has been done. I'm afraid the K&N will give a more consistent airflow through the test, but will place more debris in the oil. So I guess you have to decide between running the debris in the filter or in the oil. I run K&N but I prefer the former.
I'm looking for better milage on my 05 goldwing
So the questions is, will better air flow mod be better for your engine....if it’s dyno tuned with the mods?
Jaime yep! Built bikes will definitely benefit from higher airflow.
@@TheInja Every modern bike with oxygen sensor will benefit from higher airflow. But modern ОЕМ filters are having similar airflow rate, even compared to К&N - , and you can hardly get any performace gain.
I had a K&n air filter on my 2007 Honda Vtx and it ran like crap it would stall all the time if not warmed up all the way. I put on my stock air filter and my bike ran like a champ. Keep your money and keep your stock air filter, you will be happy you did.
That's because your factory tune/jets are set for the stock filter. The higher flowing k&n put you in a lean condition.
You have to tune for your airflow
The air filter is not restricting the engine. It's keeping dirt out. Manufacturers are struggling to keep the fuel consumption down, follow regulations and still give enough power to make customers happy. This is not done by fitting a restricting filter. It's about compression, efficient injectors, combustion chamber design, less friction in the engine and so forth. Having to worry about a filter not passing enough air during design? Not a chance in hell. The engine will use the same amount of air no matter what filter is in there. Or no filter at all...
I would like to ask this. My clothes (on my back) smelling gas, even more, if there is another person on the back of the seat. I haven't any mods..only original parts.. Is this normal?
I just washed my jacket today because it reeked of gasoline. Have you found anything out yet what it might be?
Running fuel rich maybe?
without changing fuel maps, changing filters may even be worse than the OEM air filter being that recent bikes are set up lean from the factory, and a higher flowing air filter will make it run leaner.
I think you're on to something. Even though I idled my bike about 15 minutes to acclimate the ECU to the DNA filter (similar to K&N), my bike had issues; I don't believe that the ECU could fully compensate for the change in airflow. Though it ran and sounded better, the fuel and power delivery were snatchy and jerky. The bike also vibrated more; though the balancer took care of the primary vibes, the higher frequency, secondary vibes made to the bars. My hands tingled to the point they felt like they were asleep. SO! Even though the DNA filter gave my bike better acceleration and sound, it gave me more vibes and worse fuel delivery. The OEM filter is overall better for my bike, so that's what I'll stick with.
@@markymarknj K&n, DNA, sprint, bmc, they are all letting way more dirt into your engine over stock, no matter what they claim. And sooner or later damage will be done. The only real choice to upgrade is a foam filter MWR that has proven itself in dirt bikes and off-road for many years and we’re even used in street sport bikes by Yamaha and Kawasaki into the 2000’s, and are still used in WSBK. They are actually excellent at catching particulate while at the same time flowing more air. Some say it’s due to its 100% filtering foam construction and shape utilizing every inch of space available in the air box to flow air and filter. They have their racing line that favours air flow over filtering but obviously recommends only for racing and to clean often. Their performance line is the perfect balance of filtering and airflow for street bikes. K&n started to be used in dirt racing because race teams decided they’d rather sacrifice their engines than have to deal with clogged filters that actually do their job. Clogging a foam filter on the street is a non issue if checked and cleaned yearly at least. I would get a new one every 2-3 years as foam does deteriorate with reuse.
@@chuck1622 you're right about that too. That's another reason I returned my bike to stock, to better protect the engine. That's another reason why I removed the DNA filter from my car too; while I returned to using the OEM filter on my car to protect the MAF sensor, I also did it to better protect the engine. Now, I run either the OEM or a Wix filter on my car.
Rather than play games with my bike's ECU and stuff like that, I'm going to get a bigger bike that's more powerful. Royal Enfield just announced their Super Meteor, so I'm going to wait for it to come to the US. Soon as it arrives, I'll trade my Meteor in on it.
The K and N type filters work. Clean and oil them they work for sure you do get gains.
and you damage your engine since they dont filter out the garbage
@@SamiNami They absolutely filter out "Garbage" do you know anybody who has has a catastrophic engine failure due to a K and N filter? I personally do not. They have sold unknown millions of these filters you would think someone smarter than us in the you tube comments who designs vehicles would be warning people to not buy them by now. It's been what over 40 years they have been in use wide spread and nothing.
He's actually making really good points.
I feel like this is the kind of response which would be suitable for the car community as even the smallest parts or mods can be quite costly, but for a bike there are many standard upgrades your average rider would do that would immensely benefit from a high flow filter. This really just sounds like a Scotty Kilmer video where you assume everyone has the mechanical knowledge of a potato instead of wanting to know the true hard facts and a real comparison.
thanks for the review saved me time an money
I bought a used VTX 1300 that came with a K&N air filter, the bike really never ran right until I put in a OEM Honda filter. The facts are if you dyno your bike before and after you have a K&N air filter you really don't get that much more power but you risk the chance of burning a piston or valves. K&N air filters in my book are crap because they do let in more air but more air does not mean more power. Then there is the fact that the K&N air filters let in dirt into your motor, Don't kid yourself. Do you really think if the K&N air filters gave you more horse power most bikes would come with them? Save your money keep your OEM air filter and save your motor while you are at it. K&N = crappy running motor but you you do get a sticker showing people how foolish you are.
Ron, I too reinstalled the OEM filter in my bike. I have a 2021 Royal Enfield Meteor 350. I used a DNA filter (similar to K&N), and my bike had more power; it accelerated better and pulled better in all gears, particularly 4th and 5th. My bike sounded better; it had a more pronounced thump. Even so, those improvements came with a downside.
HOWEVER! The fuel and power delivery were snatchy and jerky. The bike vibrated more. I'm not talking about the primary vibrations; I'm talking about the secondary, higher frequency vibes that made it to the handlebars; my fingers were tingling, big time; my hands felt like they were asleep. When I reinstalled the OEM filter, all that went away. Power delivery was smoother and more predictable, which gave me more confidence powering out of turns. My hands felt a LOT better-no tingles! Overall, the OEM filter is better, so that's what I'll stick with.
Someone on TH-cam did the whole thing on air filters and K&N does make the car time limit more faster. So yeah it does work.
When standing the OEM and KN filters side by side, its quite obvious that the aperture-size of the element on the K&N is significantly larger than the OEM (for my Honda SH150, at least)... So its like a big window vs a smaller window. Bigger window is gonna let in more air. Since these things have OXY sensors, it should be able to adjust itself to more air flow. I liked your reasoning and arguments, but they assume the same size/apterature, no? I gotta figure the significantly larger opening on the element will let in more air so I am gonna go head and try it and report back!
That’s probably the small instance where the air filter element is bigger than oem, Scooters have a plastic panel with the filter built in so if K&N made it larger than it might actually help
People will always justify their decision to use K&N or any other change to their bike. It’s really meant to be a racing filter. Obviously it has to have the exact same dimensions as the factory original to fit in the air box. If it passes more air, it passes more dirt, you can’t have it both ways. More air is more engine wear, less air is less engine wear. Give the engineers who designed and built your bike some credit, nobody knows it better then they do. They know what the engine needs and gets with air flow from idle to redline and under any load situation. I have known riders who have had the same bike for several years using K@N. They often comment that every time they check valve clearance it’s too tight like it was the previous year. That’s because abrasive dirt is getting in and gets trapped in between the valve face and seat. When it closes it has increased wear because of the abrasive dirt that shouldn’t be there. The increased wear causes the valves to recede into the cylinder head, resulting in tighter valve clearances. I would never buy a used bike or car if I knew it had a K&N air filter in it.
,
Makes sense to me and preciate cha on that.. I'll just stick with the oem air filter 😁
OEM is designed to pass emissions. Performance can be put last when it comes to being able to manufacture and sell motorcycles. Hints all of the emission stuff that's added and restricts the bike. So yes Yamaha would put in a filter that works as a restrictions in order to pass emissions and noise compliance. Why do you think race bikes are Full exhaust and higher flowing air filters? The oem hype is only valid if you are trying to keep your bike as standard as possible. Yes there are risks involved with modding but its apart of game and you'll get used to it.
You’re saying k&n air filters are not better, in any way, than an oem air filter. Than how is it I picked up 25 awd hp in my 2018 sti Subaru on the the dyno vs oem. Something cleared the the way to allow more air in the motor. The same can be said with my 2004 z06, 2016 z06, 03 cobra, 2018 panigale V4s and speed triple. If you don’t believe dyno numbers, then track numbers. I don’t know what bad experience you had with a k&n but you’re just throwing out bad information based solely on your opinion. Take the the oem filter out of any turbo car and replace it with a k&n filter and your car will need a tune because it is leaner from getting too much air and not enough fuel to balance the air/fuel mixture in the cylinders.
Its also for the sound.. sounds a bit better. Better response on the gashandle. So...... why nuts?
Hiflo filters do increase HP with the right setup! But find one made of cotton OEM style! k&N let's too much dirt in your motor!
Yup, garbage in garbage out, The engine is an entire system of components that's working together, you can open up air flow all you want that won't do anything If the fuel system can't handle the extra air volume, and the exhaust system can't get it out.
If an air filter improve performance.. Companies would be using that as there main sales pitch.
Added noise to the intake on my FZ1. Fatiguing on long rides. . .
Engineering explained did physical test to see if air filters do make a difference and turns out they can make up to 3.3% more power in a car.

Thanks bud 👍
thank you brother, this was very informative & helpful! 😎🤙
Not to mention that K&N air filters tend to ruin MAFs (Mass Air Flow) sensors. I don't know if modern motorcycles have an airflow sensor of any type, but it is a well-documented issue in automobile engines.
If the bike has a catalytic converter, O2 sensors, and EFI, I don't see how it COULDN'T have a MAF sensor! The bike has to know how much air is coming in, so as to meter the proper amount of fuel, right? If it has EFI, then it has a MAF sensor. My bike has all the above, and it has an airflow sensor in the throttle body.
@@markymarknj sounds sensible. in that case, I would avoid oil-based filters like the plague.... of course unless you are continuously cleaning and replenishing the oil and cleaning the mass air flow sensor and whatever else it might affect.... but for the everyday bike, I just don't see the benefit
@@patrickneyman6739 if you're racing, then yes, you want more airflow. You'll also need to do work on the ports, install a new, high flow exhaust, and flash the ECU to ensure that everything is in equilibrium and working together. At the end of the day, an engine is a big air pump that uses a little gasoline to help it along; more airflow=more power, which is what you want in racing. Also, race engines are rebuilt regularly, so it doesn't matter if more dirt is ingested; the engine will be rebuilt long before dirt can hurt it. SO! For high performance applications, a high flow filter makes a lot of sense.
For those of us who aren't racing, then the OEM filter makes more sense. It'll capture more dirt, thus protecting your engine. You don't have to worry about damaging the MAF sensor, as the OEM filter has no oil in it. Plus, since the ECU and everything else has been designed to work together, it's best to leave things stock, particularly if you don't have a high performance bike. Once you change the filter, then you need to do the exhaust, port the heads, swap the cam, and flash the ECU. That's a lot of time and money. If you're not racing, then why bother?
Fuel injected models have MAF sensors.
it helps if you install a full system exhaust.. it is high flow though
Facts
is the stock air filter washable?
UndercoverBiker A lot of people wash their stock filter. You definitely can, just make sure you know when to replace it when it needs replacement.
thank you for the answer. V to you
My thoughts exactly! I gotta say K&N does a good job of marketing though...
“Why would Yamaha not make the best air filter oem “ .... so I guess by that logic it’s still the best stock exhaust - you wouldn’t need a power commander either - the tires and oil and coolant from the factory are the best of the best. Fantastic
Exhaust is imposed by EU regulations and so is the ECU. Oil and coolant from factory are fine. Tires depend on style of riding.
Performance air filters are bug filters, not air filters.
Thats true. 👍
Why would Yamaha and all other manufacturers not design an air filter that has great performance?
Cost.
If Yamaha would they could extract an insane amount of horsepower from an engine. Why don't they? Lifespan, fuel consumption and customer satisfaction. A stressed engine will break down faster. Would you want that? The air filter is not restricting the engine. It's keeping dirt out.
Umm soime people live in different locations such as heavy dust and particulates and KN filters are great because you can service them yourself more often, Instead of buy new paper filters which washing those is a super bad idea as they were never meant to be "cleaned". Those are one use only. I like consistent air flow and ease of use which I believe is the best use of a KN filter. and OEM filter are made to be cheap not to provide the best performance BTW.
What about the environment?
You don’t get K&N air filter to gain horsepower, you get it because it’s reusable with the recharge kit.
hi i have yamaha R15s. can i remove the air filter (cap) and fix my air filter with only screws i like the sound when the aif filter (cap) is removed. but as the intake air will be more when i remove the cap will it cause any problem to my engine
As long as all the air is still going through the filter, you're fine. If the cap will let outside air straight into the engine, don't do it.
The Inja.. the air goes through air filter only
@@Leomahe0678 then you're fine. 👍
Got a normal (4 layer cotton) K&N for my cbr1000rr and the wheel lifts a whole 1000rpm lower. Don't forgot bikes need to pass noise regulations meaning restricted exhausts and intakes. Don't have to but a ecu tune on a dyno will really bring the bike to life with a race filter and pipe (NOT STREET LEGAL) ;)
1:30 because they have EU regulations to meet. So a lot of bikes are both mapped and electronicly restricted :D so not ALL OF THIS is true!
I have very limited knowledge about this,. But alot of what you say it wrong. Most bikes around here in EU "nerfed" just because the bikes aint legal if they dont do it. So restrictive filters etc etc is just one simple way for them to lower its perfomance.
But with all the other emissions restrictions, a high flow filter on a stock bike isn't go to do much is my point 👍🏼
Its all about air flow.not hp..imaging covering your face wih blanket and a mesh..there are some diferrents..most bike now does not suck air specific to stroke or injection settings,it just suck air till you release the throttle..
This guy gets it
Mann that tip was on point. Because I need an air filter for me bike and was told that k@n was the truth. But after listening to you, I'm gonna just stick with a oem,air filter and save a few bucks😁
To be honest though, if you can experiment without consequences other than a few bucks and research time, you should do it.
@domovoibutler42 yeah ok, but experimenting might cause no riding 😁. And I don't want to spare a few bucks and especially if I don't have too. But who knows
They let more air through.. and dirt ..
Thanks even after looking at the postings I am going to buy another OEM given I am on a budget.
i understand where you are coming from but your opinion is very biased
Garbage in garbage out guys, remember the engine is an air pump . A system of systems that all work together to produce a result . Open up the inflow you need to open up the outflow , do both of these and you need to Increase the fuel flow.
I put a K&n air filter on my bike and it almost melted a hole in my piston and it ran lousy, I went back to my OEM filter and my bike runs like a champ now.
Big Ron Waggles daaaang dude, that's crazy.
That's because it was running lean. More air equals different fuel ratio which requires a tune or carb rejetting.
Did he tear down his engine and look at his pistons ? Hard to believe that changing an air filter element could make it run that lean ?!
K&N sounds great and who knows, may be they really perform better, may be not. I like hem, it feels stronger, no matter if it really is 😏
I AGREE BUT DIAGREE THE BETTER THE BIKE CAN BREATH / AIR FLOW IT RUNS BETTER I KNOW THIS BECAUSE I HAVE THE ZX 14 THIS BIKE IS MOSTLY STOCK I HAVE THE D.I.D CHAIN AND MICHILIN PILOTS EVERYTHING ELSE STOCK RIGHT NOW BUT THE K&N FILTER I CAN TELL THE DIFFERNT NOT SAYING I DOING 205 MPH IN THE QURTER MILE JUST A SLIGHT DIFFERNT IN EXCELERATION . SOME TIME THE LITTLE THING MAKE A DIFFERNT.
I agree. There's no free lunch. A good Japanese OEM filter is high quality. Why screw around
I find it really interesting how people refuse to listen to logic. When people drop serious coin on something they want to feel justified in their purchase.
Did you end up keeping it on ?
Dr Greenthumb Not sure what you mean, but I've used the original style filter since I started riding!
The only reason to get the K&N is it's washable. Which counts for a lot for some people, including myself... I buy tue Chinese knock offs of the K&N filters as they're just as good now lol
Bottom line: You wont notice any difference between stock and a k&n filters. If you say you do then your just in denial. Especially, as most of us are running stock motors with little or no major upgrades.
@Alan MacRae Thats great that you notice a difference in your motorbike. I believe if you do notice a difference, it would be on a performance sport bike like a GSX-R, KZ, YZ, or CBR. I doubt very much you will notice a difference over OEM if you own a stock Harley or stock cruiser motorbike..
My airbox is broken, so this is my only option
So K&N are wrong? Just purchased one, engine revs easier, bonus if hp goes up too 😃
Yep, those and BMC do fuck all for HP increase..you want my HP, then get your heads flowed...increase your motor CCs and add cams, spend money on a full exhaust and spend money on a decent mechanic with a Dyno. Beware no two dynos are the same. Someone will say they got "100 rwhp...while the same bike on another may read 96 rwhp. Most people need street ability and torque. So unless you're drag racing or have fitted an aftermarket exhaust with a P.C 3 or 5 etc then it's not really getting you much except for "bragging rights". Better spending your money on a track course or decent tyres etc.. OEM filters are just fine.
I installed a K&N high flow filter into my new MT09 I had 700 miles. Before in 4th gear @5000rpms 60 to 65mph. When I changed my factor paper filter to high flow @ 5000 rpms I was cruising at 70 to 75mph. My bike takes off at 5000rpms.😊
Your engine RPM is locked to your drive at any given speed regardless of power output
But output wise there is a difference than when I had a paper filter.
I don’t know exactly how an air filter would’ve changed mechanical function like final drive, but I’m 99% sure that’s placebo effect
No shortage of dyno results that prove this video wrong.
K&N filters are Good, but no were as great as Sprint filters, Sprint filters you only use air to clear and no need to buy cleaning products for, and from paper filters being at $80.00 bucks each, to Sprint filters at $300.00 each, well it will last long time 75000km ÷ by 5000km = 15, cost for paper filters $1200.00, street uses only
String filter $300.00 only, plus I gain 6.5HP top end, K&N 3HP gain, still good, but love the Sprint filters
My bike ZX1400R, Enjoy
OEM is the way to go. Period.
K&N is effective for cars IDK for bikes though
Agreed. I use K&N in my truck, and both of my cars. But, I mainly do this for environmental reasons though. As far as my yamaha tw200, I didn't notice an increase in performance and for some reason my exhaust was a bit louder and seemed to be off beat, if that makes sense.
Not their oil filters for bikes. They're not even allowed on tracks, they're so bad.
Thank you. A simple and strait forward answer with logic and facts. I should send you the 50 bucks you just saved me. Thank you man
Heck yeah man, get yourself some avocado toast with that money!
Correct, I bought one years ago....they're not worth it. OEM, they way to go. If you're racing, yes go for it. K &N or BMC same thing, they're a pain in the arse as you have to clean them with their products.
Is that choccy milk in the back?
Yes 😏
