Probably one of the nicest guys in all of KZhead. Thanks for all the efforts. 👍👍
Excellent video, even though I was expecting the filters to work. The way he explains the conditions makes it great learning
I just love your very detailed reviews with a dash of humor! Keep em coming! =D
hello folks, Absolutely authentic and transparent test. Thank you very much Sir. Best testing I've got ever seen on YT. It will be difficult to be even better! Greetings Marcel
Great test! Really appreciated the dyno run which makes this an actual test thus no statements based on personal feeling or suggestions
Respect pt munca depusă, realizez ca a ti-a luat foarte mult timp ! Excelent video!
Keep up your great work!!! Great tests, thanks!
Thank you for this video! Clear and exactly what I was looking for!
Excellent detailed & easy to understand comparisons. Thanks & keep up the good work!
Good quality for such a small channel. Thanks for your work.
Very informative videos, really liked it. Please keep uploading the great videos like this.
Awesome vid! Also so much information gained from this video so much more than others I’ve watched. TY!!
Love your reviews man!! Very scientific!! Keep up the cool reviews!! 👍🏻
Felicitari pentru continut. Videourile tale necesita foarte mult echipament si pregatiri!
Your level of effort is incredible. Amazing!
Amazing video! Definitely going to reference this video when talking about intake systems!
Best video on this subject I’ve seen. Thank you
to test the flow performance of the filters try using your diy chamber and pull air using a blower fan or better a vacuum cleaner, then measure the pressure drop inside with an low pressure sensor. For remapping the car if you don’t want to add too much extra stress on components you can try keeping the old torque up to higher revs until you reach the desired horse power. for example 250Nm @4000rpm would give you 140Hp
great video Sergui , well explaned and good documentation
Thank you for such an illustrative video.
Thanks for sharing! This was a really interesting insight into filter options
I've used a k&n drop in filter for 20 years. The same filter, just rinse and lightky re-oil. I have not had any issues with it. I've put about 80k miles on the filter and it still works great.
80k miles probably isn’t enough to notice a difference in engine life.
I believe it’s worth the price upfront. Washable filter will pay for its self within 3 yrs
Never had a K&N throw a code. If you over oil them your doing it wrong.
Yeah, ok. But has your engine been protected? Looks like the K&N is actually very bad at its main job, filtering. It was almost as bad as no filter at all in this test.
150,000 in 6 years
Thank you for this video, the result surprised me, but also pleased me, as now I am confident that leaving the original filter in my car is all I need to get maximum power from my engine !
Very well done - thank you!
High quality content! Thx! :)
Conținut excelent, tine-o tot asa. ✌️
After so many years of pondering how really those filters outperform one another now I got the clearest idea. Thanks for this very helpful info. More please on some aspects about car performance!!
I loved this video. You are bringing the truth out. Many people don't believe me when im explaining this to them.
Very good information, definately an eye opener for a lot of people.
Excellent comparison. Thank you.
clean video - great work!
Excelent video-ul! Cautam asa ceva de cateva luni si nu pot sa cred ca am gasit chiar de la un roman, felicitari! Mi-am luat un filtru con pentru masina si, chiar daca suna mult mai bine motorul, nu puteam nici cum sa merg cu el linistit pe strada ca si daily driver. Tot timpul imi statea pe cap ideea ca "da, acum e bine, dar in 20.000km cum va fi?". Multumesc tare mult, m-ai salvat de o groaza de stres! Subscribed
It would have been interesting to see how the filters performed after the remap. Thank you for video and information as per usual.
Yes, exactly! As the original filter is well calibrated enough for the original power, doesn't it limit the power after remap?!
This. Performance parts benefit greatly after a remap I was able to achieve 20bhp with just CAI and downpipe.
@@gwenc8900 It definitely does. I had a remapped 1.4Tjet with a slightly bigger turbo . It did 180+ on dyno with stock filter.After upgrading to a aftermarket performance filter it gained like 5hp. It did 184.8 .9
@@whitegptjet I think it's placebo effect here. I have a 455bhp/634nm custom mapped M140i, and I use the standard BMW air filter. Even at the power I am running, the various air filters I tried made zero difference. You have to remember, BHP can not be measured, only calculated, and if you put the same car, on the same dyno, with the same filter fitted, and do 10 dyno runs, you will get 10 different figures. So many things come into play, and every dyno & mapper has their own calculations for measuring BHP. Any tiny variations of plus or minus 5 BHP are simply down to these natural variations on each run. People are always looking for gains on engines and believe any old shyte, and performance filter manufacturers are just selling a dream. An engine is basically just an air pump, and so long as you are getting enough air into the engine (even from a standard filter), the intake temps, timing, and fuelling can only do so much. Adding more air flow from the intake won't gain you any extra power unless everything else is adjusted to balance that out and take advantage of it. The thing which is holding my car back is fuelling, and to get my engine to around 480-490 BHP an upgraded high pressure fuel pump is needed. I could fit one and keep the standard air filter, and still get the same power regardless. Just for balance, I work in the motor industry too, and actually sell parts including K&N filters. We had the reps from K&N in to our office, to 'train' us about their products. We all came away with the same opinion, which was basically overpriced shyte.
@@DjNikGnashers Hi. I believe you. All turbos work the same: they are set to gain particular overpressure compared to non-turbo engines. If there is too high air pressure special valve releases part of this additional air or there is mechanism inside turbo which decrease air pressure (depends on model). So until we don`t have too much overboosted engine k&n air lifter shoud not give any gains.
Excelent ca de fiecare dată! Eu de la tine am aflat și de atunci tot Mahle iau. În plus, îs făcute la Timișoara. Dacă ai putea testa și cu motor aspirat natural ar fi ceva. Totuși pentru 2-3 cai în plus, nu știu dacă are sens uzura în plus a motorului, mai ales la cât praf e la noi...
I love this topic thanks man
An honest review a breath of fresh air
Fucking hell, what a quality video. Mad props, mate. Thanks for all the time and study you put into this!
Great video and comparison!
Awesome work & thank you!
Thank you for sharing this. Hopefully I was able to change my filter out soon enough to prolong the life of my engine.
Thank you for your contribution, quite rewarding. 😊
I appreciate the information and what it to took get it...so thank you my friend. You saved us money. Subscribed and like!
Really good and clear video, thank you so much from italy
Thank you for the proper explanation of having direct intake air filter vs placing the filter exposed under the bonnet
thank you man . i like all your pro videos !
Thank You for this information!
Excellent review! I love the evidence based decision
Amazing explanation and experience, congratulations very very good job. Liked the scientific approach
This was an excellent video, thank you
Great informational video! Thanks👍
Absolutely excellent video!
Thank you. I just ordered an AEM to replace the K&N engine air filter on my car. I put a Mahle in the cabin this time but I'll most likely put a K&N one in there around my next oil change. Honestly got it for the reusable aspect rather than performance. I don't like waste 😅 but i also don't want my engine to go to waste from the lack of filtration from K&N so thanks again for this video 🙏🏼
Makes no sense. Why would you put a k&n cabin filter in next time
Very informative video. Thank you.
Excellent video!👍
Thanks for the informative video
thank you so much, you're a gift!!!
Excellent explanation 👌
Thank you. I learned a lot.
Good job mate 👍 thankyou
K&N is the manufacturer of AEM and Spectre. All of the filter types cross over between all of them. I've worked at K&N for years.
Good demo, you answered my questions.
Thanks for your review and information ❤it
By far, the most reliable, easy to understand, not wasting my time, scientific test, I have ever seen!!! I am also an engineer in Auto Sales Business, who has a stage1 remapped Z4 20i. Now, If you have renewed the test after you remap your car, this video should have been your Phd :) please update it while your car is remapped.
I Would like seeing you making a Test with a Pipercross Airfilter. Really great Video and great to see all the Results you got out of there .
With all the information so far, I think Sotck OEM Mahle Filter will work well. Also, You have done good work and put great effort for this video. Kudos to you have thank you for your efforts.
This man is sth else.huge respect for you mr.gabor
Awesome video man!! I like your cientific approach, been a cientific myself! You even had a 3D printer (pink filter holder) and do arduino stuff! Great!! I was wondering if i should change the standar filter in my Jeep Wrangler with a Pentastar engine or keep the paper one (a high quality japanese one). I will keep the one I am using, cause I live in Chile and climate is desert, so a lot of dust everywhere and the oiled ones get clogged fast. I will only change the intake hose and get rid of the resonator. Thanks a lot! New subscriber here!
Your videos and your presentation are awesome. You should keep doing this.
Merci ! C'est une excellente vidéo 😀
Awesome Work
Great video - subscribed - thanks!
I'm surprised the AEM is so good without any 🛢️ on it that's impressive for being a "dry flow" filter so there's really no chance to mess up your mass air flow sensor from the oil 🛢️ on the filter + easier 2 clean👍👍
@@you_can_fuck_your_own_ass_69 no its been debunked that oil gets on a sensor after it has been oiled properly. Keyword. Dont over oil it and you will NEVER have a problem. People like to WELL over oil thinking more is better. A very light coat of oil is all that is needed. Never had a problem in 35+ years.
Excellent video! I was hoping to see a comparison to the aFe dry filter -- but this is a great start!
Thanks for this video
Thanks , great job
thank you, great video
I've learnt a lot from your video. Thanks. Next time I need a new filter, instead of forking out £20 to £30 for a new one, I'm going to cut out the filter material from the old filter and replace it with a few layers of J-cloth or microfibre cloth. I reckon this will cost about £15 to £25 LESS than a new filter and will probably work just as well. I might experiment with soaking the cloths in the oil used to lubricate chain-saw blades as this is quite a 'sticky' type of oil.
I kinda like that the AEM doesn't need to be replaced as often. Not surprised that OEM is ideal for a typical daily driver.
KN is exactly the same.
Higher flow air filters are better for forced induction vehicles with either turbo or supercharger.
@@user-is1xn4xt9nThe opposite: are better on NA engine. On new turbo engine air pressure on intake is constantly measured... If is less the waste gate open later to give same air pressure. Obviously in standard condition... If you make big tuning is different.
@ziofrenko not always as my car has twin turbos and doesn't have a maf sensor, my car uses speed density by a boost pressure sensor and a map sensor. Thus getting g more air since the wastegates are electronic controlled and by boost pressure only. Most newer cars use a maf sensor aka Mas airflow sensor that meters measured air coming in. And adjust fuel and boost accordingly. The only place u run into problem is by running a bov on a maf car and can cause the car to run lean or to rich and stall. On a car with speed density it doesn't matter. As there is no maf to Metter air coming in. Also having a high flow air filter doesn't effect either vehicle only bov or bod aka diverted valve. And a tune. But just a filter ur ecu should acount for more air adjusting a/f ratio and to do it properly u have to remove negative battery cable and wait a few hrs then re connect this will reset the long term and short term fuel trims. And force ecu re learn.
Thank you for the video :)
thanks a lot man. too many speculations about these types of air filters....
I put an AEM in my new Subaru as soon as I got home from the dealership. It’s been a year and thanks to your video I may swap back to the OEM filter
Great video, thanks!
Great review thanks for pulling this together!
GREAT JOB!
Very nice. Thank you!
Top o vídeo!! 👏🏻 🇧🇷
That recyling gave me an idea. I checked the part number for the air filter in my car, and turns out all BMW E46s have the same filter, from 316i with barely over 100hp to M3 CSL with 360hp.
That dyno graph looks fun!
Really awesome test!
Benson and Gabor two of the best testers of automotive products on YT 👍🏻👍🏻
@@RickyG84 😁 don't forget the king of us all, Project Farm! :D
interesting test&video! any plan to test foam filters (i.e. pipercross, Revo...) and polyster (SprntFilter) ?
Bune documentația și testele, felicitări. Iar concluzia...cine vrea sa fie sincer cu el însuși...
Hi. I think you did a very good job comparing these filters.. i'm a fan of using performance filter that use sponge like material as the filter medium. Hope you can also compare those kind of filter in your next video. Old bike and dirt bike usually uses those kind of filter, and it make me wonder, how does it compare to the other kind of filter.
Hi. Nice video. The experiment about the dust is very importat. I need to mention that at new cars 2013 year and after putting a different filter ecu needs 3-4 days to read changes about air mettering. Fiesta 1.0 ecoboost 140ps. When i put k&n filter, hks and original the differences were after the third day. I start seaching about that and that happens.even new bikes
Excellent video
Cool test.
I used Green Filter, I don't know if this brought more power, but the engine responded a little better and consumed a little less. Engine sound was better. Good Test!
Hey mate thanks for all the tests u do, i got a 2019 audi r8 performance and cant decide which oil to use. in the tests ive watched from you motul and ravenol are on top and liqui moly is up there aswell. Which one would u recommend?
Manoll
Thanks for this review, I like K&N filters but knew they let in too much dirt so I dont use them. After seeing this, the AEM is comparable and is a better filter as far as good air flow with good filtering.
I used a K&N filter for like 150k km and now the engine consumes alot of oil :(
WIX is actually doing the same as AEM, but WIX is a lot cheaper. If its about filtering micro dust, take Hengst or Alco filters.
@@bogdaniojescu5889 I just bought a k&n filter🤦🏽♂️🤦🏽♂️ is it really that bad
@@nizo6673 my engine had 358k km and it eats 1l of oil every 300 km.
@@bogdaniojescu5889 Is that due to the air filter, or is it just worn from all the use?
After I have seen your vids about the filters it let me thinking if a K&N is the right choice. They filter less dust ( in my area it's not dusty) and no big hp benefits. I have put this morning a K&N filter in my Seat Exeo with 2 liter engine. The main reason for me it's the sound it gives. Now I hear the turbo sucking air and I love to hear that. I have cleaned the air hoses before the filter just to make sure I don't have unnecessary dust that could harm my engine
well done! very interesting :)
