We tested 4 of the best performance air filters to see which one was the best. From their ability to filter out contaminants, their capacity and horsepower increase. We are diving deep to see what makes these filters tick. So if you want to find out which one takes the crown, then stick around. #engineairfilter #airfilter #test #K&N #AEM #SPECTRE

Project farm showed K&N let a lot of contamination through the filter! There’s no need for a performance filter!
Project Farm's test used invalid methodology. This test is far better.
Running absolutely nothing is better than a k&n filter lol
@@tid418Invalid methodology? In what way?
@@tid418And this year came to the same conclusion...
He dropped the dust on top of the filter, with gravity assisting in pulling the dust down through the filter. That is not how contaminants enter an actual filter in a car.
Air particles are entrained in the airflow into the filter as the air passes through, usually flowing from the bottom upward in modern vehicles. Any electrostatic treatments a filter may have to trap additional dust are negated when the dust is just dropped onto the filter, and filters that are oiled can have local areas of dust saturation where the filter momentarily dries as a large bolus of dust temporarily "soaks up" all the oil.
This test duplicates actual conditions much more accurately, and closely mirrors the test protocols used within the filtration industry.
I like PF and have long been a fan, but not all of his tests mimic real world conditions. His motor oil tests miss nearly all of the important bits about motor oils, for example. The bearing test is indicative of metal on metal contact under high pressure, which is not supposed to happen in an engine.
Those tests will favor oil formulations high in zinc, and while that will give you an idea of what might be the best oils for flat-tappet engines, it ignores the rest of what makes an oil good or bad. Modern oils have limited zinc to protect emissions components, and that's not a problem for any cars with roller lifters or overhead cams.
I don't fault PF for this; he does not have the laboratory it would require to be able to test the rest of the stuff. He is very entertaining and I watch every one of his videos, and I just bought another infrared thermometer the other day because of his tests (it was $9!), but the methodology for the air filter test was flawed. There is a reason that the filter companies don't test that way.
These kinds of videos are exactly why I love this channel. THank you for your work, and please keep it coming.
Thank you for the kind words! We're happy you enjoy the content!
@@BrandRankscan i use HEPA air filter on my car? I want the best filtration for my car engine
I have a 25 year old Integra that I bought new and it has almost 300k miles. I installed a K&N performance cone filter on it a month after I got the car and the car still runs great today. I don't drive my Integra as much today but when I use to drive it all the time, I would do 7000 mile oil change intervals and it would burn about 1/2 quart in that 7000 miles which I think is pretty good. The engine still runs strong. I still take it up to redline and I never feel that the engine is going to blow up.
If K&N air filters were bad for your engine, you'd see a bunch of videos from people who's engine was destroyed by a K&N but all I see are videos saying why K&N air filters are bad for your car but they never show the actual effects of a K&N which would involve a total engine teardown.
Your factual, real world experience should put an end to the debate. I have 70,000 miles on a 2003 Suzuki SV1000 motorcycle that had a K&N installed when I purchased the bike new. It's oil consumption is also very minimal and the performance is still quite stimulating, if you know what I mean! Wink wink.
You should have included a "standard" paper air filter for comparison in all of these tests, especially for the filtration test. The whole point should have been whether these so-called "high flow" filters are meaningfully better than the typical fram/purolator OEM style filter.
we already know that. Yes, they increase performance slightly at the cost of slightly more dirt getting through, which is considered negligible as far as harming your engine. The increased fuel economy claims are bullshit, the more air you let in, the more fuel you have to add.
@@Mach141 the less restrictive the filter is, the less the engine needs to work to suck air in. It’s called pumping losses. The claims are not BS. That’s why EGR increases efficiency on gasoline engines. You burn the same amount of oxygen, but are actually opening the throttle slightly more since some of the vacuum is taken up by exhaust gas.
The same can be said for exhaust modifications. Engines are air pumps. Less energy spent pumping the same air = less energy spent.
@@malachihornbaker5869 Yes, I get pumping losses. My argument would be mpg gains from pumping losses are less beneficial than the extra fuel your burning because your now making more power. The claims are bullshit.
I just stick with WIX air filter. I hope I make a good choice. I not sure how good it works though.
Make sure to watch our first video on air filter. Wix did very well! Thanks for watching
WIX is the top of the line for non performance filter.
I use a WIX in my HiHY . Very stiff construction compared to others. Easy to vacuum out. I change oil every 4K miles and it looks clean, this is on an engine with 150K miles. I change air filter after 20K miles.
WIX makes the best filters for oil and air in my experience. You’re good.
I gave up on "performance" air filters and WIX is always my go-to brand, too. I'm convinced you can't get high airflow and high filtration at the same time. I just get a WIX filter and change out frequently...
Love this video! The visuals are incredible ,they've got me geeking out over air filters! Never thought I'd be inspired to change my air filter, but now I'm eager to upgrade for better airflow.
Thank you for your continued support! Always here commenting! We notice and appreciate it.
You guys are the best! Love your test!
Been sharing with my car groups your guys awesome videos!
Thanks so much! Really appreciate you sharing our videos with your car groups! 🚗🔥
I had a 2020 Ford Ranger with the 2.3 liter. I got a performance tuning kit directly from Ford. The kit was a reprogramming of the computer and a K&N air filter. It's interesting that the manufacturer had no problem with the K&N. This was an easy way to get a great power boost and keep the warranty.
That's because car manufacturers don't care about engine longevity, once the warranty is done they wash their hands of you and hope you will by a new car....
@rankinewasyn5369 Probably true. I will say the thing was pretty quick once I added the tune kit.
I’m here for it!!! Love your videos and the info you provide!
Thank you! Glad you’re enjoying the videos and the info! 🙌
@@BrandRanks The cotton filters such as K&N need the air coming in to pulse like an engine does, so you need a rig that will do that. Without the fibers receiving air pulses, the dust will go through. Just a straight flow of air without pulses is an unfair way to test these type of filters. Please watch this video "K&N air filters undeserved curse lifted!" Then build a new rig, or modify yours and see what really happens.
@@Sagina1999😅 can't tell if serious
@@ianm432 Can't tell? Yes, as serious as a heart attack!
@@Sagina1999 I manage a fleet of construction pickups. One of our drivers put a K&N in his work truck because he was "tired of having to clean his filter all the time". We had no idea he had replaced his filter until his truck went into the shop for a turbo replacement (at way lower miles than we normally see a turbo fail). The mechanic sent us pics of the intake completely coated in dust. Then he sent me a pic of the K&N. That turbo replacement was thousands of dollars, not to mention that the engine probably won't see a full life either. We only get about 3 months out of our paper filters but it's still much cheaper than major repairs. It is now our company policy that anyone who makes unapproved modifications to a company truck can lose their job for it. Pulse or no pulse, they do not filter dirt as well as a good paper filter!
This is great news you can use, thanks Brand Ranks!!
Thanks for watching!
I have 375000 km on my mazda 2, with the K&N air filter and the engine runs as good as new. Thank you Sir for the video.
Wowww that impressive! You must take great care of it. Thank you so much for watching and supporting us!
I had a K&N on my old forest service truck because the stock filter is almost $40, so it seemed like it was the obvious choice. I pulled it out after less than 500 miles because there was light dust on the "clean side" of the air box. Also if you over oil these filters the mist will compromise your mass airflow sensor. K&N good on the drag strip to keep moths out, not good off-road. I was told that I need a dry pre-filter sock by a local off-road shop, how do you do that on a stock air box? Pass.
So, you needed an air filter. for. your. air. filter? Um... Yeah. Hard pass.
I've been running K&N air filters in all of my vehicles for the past 30 years. All of the Lexus and Toyota engines never used any oil, even past 212,000 miles, but my Honda Accord Coupe starting using oil at about 70,000 miles. Hmmmm. Could it be the manufacture and not the air filter? All vehicles used the same maintenance schedule with synthetic oil.
@@m.newman7722dude wasn’t knocking k&n. He was saying it doesn’t work for his specific use case. Oiled filters take way more care and feeding off road.
Well yes and no but yea@dennisgreiwe2078
@m.newman7722 Highway cruiser with minimal dust, K&N is okay. I'll bet if you took an oil sample, though it'll be out of spec for silicates. It's not a question of if these filter allow more dust into the engine, but how much more do they allow in. And for how cheap air filters are, 30 dollars a year I'd rather have better filtration than 11 hp. Especially when I drive my car on the interstate.

ANOTHER great video! Love the content. Side note, it would be awesome to see you guys test some racing oil filters! Throw in a Fram Racing & Ford Racing! Goes great with this performance filter video! 😊
Thanks for the support and suggestion! We'll keep it mind!
Awesome love your videos .. I have more brand ideas for performance filters, PRL, AFe, BMC, Green Filter, KAK, DNA Motoring, HKS Super filter..... And for the regular filter you can do dealership filter like Honda, Toyota, etc.
Green filter USA makes PRL air filters, there is also Green Filter Europe which is different from Green Filter USA
Missed on not including the values from the last video with traditional filters. Particle counts on those were about ~12000 vs. the ~18000 for these performance filters.
I was just looking at some of these air filters last night... good timing. Thanks for the heads up on rockauto also. Almost paid triple for one Spectre Performance.
Great video. Keep in mind of the "Magnuson-Moss Act". Part of the reason K&N's warranty is the way it is because the manufacturer has to prove that a 3rd part/aftermarket part is what caused the problem. Way too much speculation over the past several decades over the K&N filtration, performance and longevity of both the filter and engine it operates with. I have never seen an engine fail from an aftermarket filter let alone know anyone who has proven it caused a problem without user error/neglect. If these aftermarket filters were so bad, engines would be blowing up left and right and these companies would go out of business. You should watch videos of folks around the world with performance filters in their off-road vehicles running these type of filters with no issues. Not to mention it doesn't help when you hear people parrot the same old exact negative comments of things like, "the oil made me get a CELL even though I technically over oiled it", "it killed my engine but I never cleaned it for over 5 years driving in dusty country backroads", etc. etc. It's not a black and white answer as it's a combinations of factors but one thing for certain in my experience is I've never seen an aftermarket filter cause engine issues without user error.
Most people trade in their vehicles ever few years like they do with cellphones to the point they'll never really truly know if their filter did cause engine issues.
Would love to see you compare stock air filter contamination levels vs these. K&N and similar have always let more dirt in from what I've seen, especially when not oiled etc.
Great idea! We'll keep this in mind for future tests. Thanks for watching.
If it's not oiled then it's not a proper filter
Who the hell replaces stock air filter after 6 months of using it? I do 20 000 km per year with the car, after that time the stock filter required a bit of compressed air and survived another 20 000 km. So for me it's 15 euros every 2 years. 4:23
applying compressed air to air filers is a really bad idea, it makes the pores biger allowing more dust particles go thru the engine
Great Video!
Thanks to all involved for a your hard work and efforts.
You are appreciated!
Thanks again! And bring me more please.
I did my own flow test using my 6" duct fan. Was it scientific, no. What I did notice was a Napa Gold for my 2002 Envoy that I blew the dust out of, out flowed the K&N and Air raid cone filters for my 5.9 Cummins. I'm going back to paper for the Cummins.
Oh, don't be fooled by the K&N 10 year $$$ savings Jedi math trick. You need the cleaning and oiling solutions along with your time plus drying (down) time.
Another great video! I'll stick with my Wix air filter given that I live in a rural area amongst farm fields and gravel roads.
Thanks for watching! Wix is a solid choice!
What most people dont know is that k&n owns spectra filters thats why they do pretty good
Yeah, also AEM filters. I Bought an AEM filter and literally, it says K&N on the side 😂
Keep these awesome videos coming!👏 The best on RUclips....
Thank you so much for those kind words. Really do appreciate it!
I'm glad you guys tested the Spectre filters. I also have been using this brand for over 10 years and the filters are really good and on average half the price of the K&N filters.
The round one I have, the filter media and metal mesh are good, the rubber converted into a tacky jelly dough. Not reusable anymore.
Great video, as an AEM user I feel this is the clear winner because of filtration which is more important than a few hp extra. Was happy to see AEM excel in filtration. Cheers
Indeed it performed better than the others filtering and it's still washable! Thank you so much for watching and supporting us. Cheers!
AEM is definitely better at filtering and it gained power and increased mpg on my dyno run, V6 VTEC kicked in YO 😉 OEM Honda air filter 245whp and AEM 257whp
But you know what did better than the AEM in filtration AND had less differential pressure?
Every single filter in the stock-type filter test. Every one. I don't know why BR didn't put those test results in with the new ones, but if you think filtration is most important, then none of the performance filters are the best choice.
I have AEMs in both my Mustangs, but the stock panel filter replacement in the newer one is coming out in the next few minutes. The conical style on my other one is still larger than the stock filter element, which will reduce the pressure differential, and it's on a CAI that can't accept a panel filter one way or another, so that one will remain.
@@tid418I don't know why any of the performance filters manufacturers haven't made a filter media that works as well as OEM paper while still being washable. It seems that they prioritize air flow over filtration. I'll probably be removing my AEM intake and going back to stock after seeing these tests.
@@JamessLuner-wi2qs I have used my AEM for over 3 years in all type of conditions snow rain off road high pollution areas railroads etc. etc. and the AEM has performed stellar in the cleaning department. Zero dust or any dirt on the clean side of the air box. Like new condition. Best part my mpg went 2mpg up
Used K&N in every vehicle I've owned. Never had issues never felt "gains" either. I used them cause I like the washable and reusable. And granted I didn't live in dusty areas too.
Washable and reusable is very convenient. Thanks for watching!
I've been using K&N air and oil filters for over 20 years . I have them in a 2011 RAM 5.7 Hemi with 280k miles and in a 2012 Subaru Impreza with 142k miles. Not a single mechanical engine issue. I'm sold.
ive used spectre from amazon in 2 f150s and 2 v6 escapes, wonderful and not paying for KNs advertising.... tho i have one in my mustang!
@@mos8541 "not paying for KNs advertising" instead you are supporting slave labor in c c p chin a! Good job! All hail the peoples air filter!
There is more nuance to it than "good/bad". If you live out in the middle of the desert, not the best idea to run a K&N. If you live in Washington where you have a whole lot more rain than dust, the 'impact' is going to be substantially less just because the outside air that your engine is pulling from is substantially 'cleaner'. In the case of the latter, I very much doubt anyone actually realizes an engine lifetime decrease - frankly, regular oil changes are just as important, because your oil/oil filter are collecting and filter the stuff too.
Agreed. I've run K&N traditional pre-oil air filters in many apps and never an issue. My 03 Cobra made great power with an old K&N FIPK, and everyone used to try and push a JLT or whatever, and I was like, "why change? I'm making great numbers with the old K&N FIPK." I do run a JLT on my 03 Lightning, but when I still used the factory air box, I always used a K&N. I DD my 02 Catfish SS for nearly 5 years with an aftermarket lid, and a K&N. My wifes F150 3.5L is running a K&N Select, as did her old 13 Taurus SEL. My 18 F150 5L is using a K&N pre-oiled filter. I ran a K&N in my 19 1SS 1LE. I ran K&N's in several 4.6L 2V vehicles. Never an issue. I don't want to dismiss the importance of filtration, but at the same time I've known people (plural) with pre-AFM 5.3L Silverado's that ran fine at over 300K that also used K&N's. If I felt like I was shortening my engine life, and accelerating wear in my engines, with a K&N, then I wouldn't be running them.
I started using K&N filters way back in 1972 on my Honda 750. Used them all the years since on every vehicle I owned until 2015. That’s the year I bought a Polaris RZR side by side. It was a 2010 model. The very first thing I did was add a K&N filter. I had been to two different Polaris dealers who both mentioned off hand to never use a K&N filter. I thought they were full of bs and even recommend that my brother-in-law put one in his RZR. After a couple of rides his RZR stopped idling. We took it to the dealer and they found that the intake tract was all dusted up and the throttle body had to be replaced. I checked my RZR and found dust in the intake. We both switched to oiled foam filters and never had any more dusting problems. My brother-in-law also had been using K$N filters in all his vehicles for years. We have never used them in anything since. Hard to believe after all those years I found out the filters were sub par.
I have been using K&N performance air filters for over 20 years in many vehicles. I have never had any issues with engine wear or anything else for that matter. I believe if you change your oil over 5000 miles, that will destroy your engine faster than using a K&N performance air filter. I also believe if you live off a country road with a lot of dust or in the desert than it can be of more concern.
Oh, the video I was waiting for, true to your word Brand Ranks. ♥
Thanks for sticking around and watching! Glad we could deliver what you were waiting for!
Love the content and the metrics your channel provides.
I would love to see how other performance filters like Injen dry filter, AFE Pro 5R oiled, and AFE Dry Flow would perform; also ITG and HKS foam filters. Does a prefilter help or hurt in any significant way (restrictiveness and filtration)?
Thanks again for your videos!
A well designed cold air intake with a sufficiently large paper filter gives all the performance required without causing engine damage. Beyond letting lots of dirt through, these performance filters tend to get filter oil on the Mass Airflow Sensor wire and throw off proper airflow readings. Unless you're doing controlled track racing these things just wind up ruining your motor over time.
what a great and very detailed video! im a fan of foam intake filters... there is also many debates on the internet which one are better between cotton gauze and foam filters... could you test the foam filters next? cheers!
I have a K&N on my turbo Volvo. Performs well and makes more power than any of the cone filter setups which cost way more money.
YOU GUYS MAKE THE BEST VIDEOS!!!!!!!!!!!! LOVE THEM!!!!!!!!! KEEP THEM ROLLING!!!!!!!!!
And this is why I like test in general. Good stuff!
I'll still stick to oem because I value protection more than power or efficiency, but good to know if I ever get back into racing 😂
Using OEM parts is always a safe bet! Thanks for watching!
Very useful information, any increase in performance or money saved by washing the filter is negated by the engine damage
Indeed I would be careful and maybe just limit use for the track. Thanks for watching
Y’all should test an oiled multi layer foam filter. They are standard for offroading and I would love to see if it is better than paper.
Thank you for the suggestion and for watching. Greatly appreciate your support!
Woww You and ProjectFarm are just great at all these type of videos! Y'all should really duo up for a few "expensive side videos"
Indeed he is great! Would love to do a Colab with him one day. Hopefully his audience convinces him 😊
They both did the test wrong, though. The engine pulses, which supposedly makes the cotton fibers scrub the air.

ive used K&N for my previous cars and current one and they worked well. drove them into the ground with these filters. but its not just dust. i often clean out leaves, small sticks, fluf, etc. so it still needs to be cleaned. Thanks for these tests!
Thank you so much for supporting and watching!
@@BrandRanks still waiting on a video about cartridge style oil filters vs can oil filters 😝
10:13 You guys have been testing oil filters way too much. 😉 Love your content!
Hahaha what I was referring to was that both "oiled" filters KN performance and Spectre. But I did mess up several times while practicing hahaha too much oil filter testing😂 thank you for watching
Great work. Only thing i wish you would have shown the Purolator stats across the board like you did with the hp. Especially the filtration numbers. Ive watched all your videos, but no way i would remember the numbers
I remember seeing this in the past somewhere. The reason why K&N gives you performance gains is because it's basically like not having a filter 😂
My 2024 GMC air filter monitor thought there wasn’t one installed when I first put it in.
Reset it alls good.
The vehicle owner doing their own light maintenance such as changing out their air filter should always be sure that any recommended replacement filter actually fits the same as the OEM. As a technician at a dealership I have thrown many K&N filters into the garbage because of large air gaps around the perimeter. I grew very leery about using these filters because of it and having uncertainty about ability to filter small particles as well as a paper filter with a lot more pleats than the K&N.
Agree. It's definitely important for vehicle owners to ensure proper fit and quality when choosing replacement filters. Thanks for watching!
@@heystarfish100 These filters seem to shrink after a couple years or service, require labor and recharge kits to maintain, filter poorly, and ruin MAF sensors. You're putting them exactly where they belong. The cons outweigh the pros or every car manufacturer would have adopted K&N filters years ago.
I had mine in for one oil change and my MAF was coated in oil/dust (from going off road) and my intake hose had oil coating with dust. It basically spits oily dust through it. I always advise people not to use them, especially if they go on any dirt roads. It allows more air which means more dust and small particles. Good for the track but not good for any adventurous person
"And more"? Got me hooked lol.
Great comparison. Can you do one on the filters after they have been washed and recharged? I feel that the paper expands lessening the air flow.
I love your testing methodology! Thanks for all the hard work.
That said, I have two bits of feeback: improved labeling, and (in this particular case) repeat testing on filters that are designed to be re-used.
First, could you label the graphs more completely? The particulate graphs had sections in blue, green, and orange but they weren't labeled, so it was hard to tell what I was looking at.
Also, toward the end of the video, you showed a comparison of the results, but only showed limited portions of the data at one time. It would be more helpful if you could display a single large table/graph that shows all the testing results for these (and prior) air filter tests. You did something similar for your oil filter tests, and similar channels like Project Farm do that at the end of their videos, too.
Second, since this video covers air filters that are designed to be washed and re-used, I feel it should inherently be part of a complete test of those products to wash and re-use them in order to see how their qualities hold up over time.
Thanks again!
Thank you so much for taking the time to write this feedback we really do appreciate it. The graph labels were really small at the top, but I will increase the size for next time and agree a table at the end with the previous filters would be useful we just recently changed tables and graph software because it used to take so long just to animate those. We were planning on doing a video regarding cleaning the reusable filters as well as passing compressed air on non reusable filters to see the impact kinda like a myth busting video. Thank you so much again, your support and feedback is amazing!
You’re going God’s work. Thank you
Thank you so much for the kind words! Appreciate your support!
david vizzard proved that there is something most filter testing rigs cant do.which yours dont do either.is individual intake pulses the cylinders create when an engine is running.if you dont believe they exist.put a vaccum gauge on any intake port of a 4 stroke engine.these pulses viberate the fibers in the K&N in an actual engine more so than any standard constant vaccum testing stand.hence why they generally test so badly.this was not K&N saying this but david vizzard himself.
Most these comments seem like they dont know how to maintain them either.
Wow real science Thank you very much
I like AEM because dry flow. Would love see cone air filter from all brands aem, aFe, injen, DC sport, K&N, and etc
Great video
AEM did indeed filter better than the others so it's a safe bet. Thank you for the suggestions, we'd like to test come filters as well. Thanks for watching
the oil soaked cotton filter in the performance air filters work best along with engine vibrations. that's the way those fibers catch dust it seems.
so a simple tea strainer type test will show the filtering is bad. some kind of vibration should be added in testing
I had to run a K&N on my Jeep because I couldn't find anything else that fit so I checked on it frequently to make sure it was oiled enough to keep the intake clean.
Happy Halloween!

Thanks for the great content
You're very welcome! Thanks for watching!
Very thorough testing
Thank you very much. Thank you for watching and supporting us.
Well that’s good. I’ve used spectre for about 4 years now
I been using spectre since like 5 yrs ago very good and not a lot of people know about it gives the same performance as the k&n honestly
I used K&N, OEM replacement air filters, three different times. All of them failed. Two of them, the gasket material shrunk and they fell into the air box. The third passed so much dirt, the intake manifold, was coated with dust, inside the runners.
Long story short, I went back to using Wix filters. Filters are cheap, engines are expensive.
Test HKS panel filter! Interesting design compared to paper or “performance” filters
They are junk and breakdown overtime like all foam filters
When I lived on the west coast and spent a lot of time in the desert I never ran an oiled filter in any of my stuff. My son lives in West Texas and also doesn't run an oiled filter because of the dust. But on the East Coast where I live now, oiled filters seem to be okay.
What do you think they use in baja?
@____MC____ The owner of the team that I worked for did not like running oiled filters on his cars. So on our class 1 and our class 10 vehicles we ran paper filters with pre-filters because that is what the owner wanted to run on his cars
For a while I used K&Ns and found they not only let a lot of crap thru the filter but if your MAPF valve is near the Air Filter, Oil from the K&N contaminated it. Please check out Project Farm's Video on the K&N. I've used Wix Air Filters for some time and been very happy with them and would gladly sacrifice the minor performance increase for greater engine protection.
Reminds me of cold air intake. Most don't increase horsepower LAMAO and people spend 500
1950’s cars have oil bath air filters, K&N may have improved this method slightly?
Really appreciate this video. It's cool to know the gains are there when you need them, but for me personally, I would not run the K&N performance daily. Perhaps if I were going out to race, track day, autocross, or dyno I would consider switching for that. To me the slight performance does not justify the increased contamination inside the engine.
I have been using K&N since early 2000s not sure if they helped but never experienced a negative aspect. I recently bought a K&N for my house AC system and it caused issues with the operation, I was noticing reduced heat in areas, checked everything I mean everything then decided let me pop a cheap throw away filter. System immediately went back to normal, by normal I mean there are two rooms we keep the doors closed that would get nice and toasty with heat on that weren’t with the K&N in use. Swapped to throwaway (of same Merv rating as K&N) immediately brought both rooms back to be toasty. I was shocked at how restrictive it was and disappointed because it wasn’t cheap but I’m sick of changing them so often.
Aem dryflow here. Always have, always will. Aem since new, and now with 225k still going strong (4.6 3v)
It did indeed filter the best so makes sense you have all those miles, but it's also most likely because you take great care of it. Thanks for watching
I've been using Spectre air filters for a long time now. Great filters at unbeatable prices. I will say their cone filters don't have the same quality as their panel filters. The cone filters usually need additional silicone applied around the pipe connection for a proper seal. Otherwise, they're great too!
Thanks for the info, we may do a video on cone filters and will be vigilant. Thank you so much for watching!
I live in Houston and there is nonstop construction, so there is alot of dirt and dust that I drive through and that's why I stick with factory filters...the increase in HP ain't worth the death of my vehicle
Breathe taking results 😮😊
I've used K&N, AEM DRY Filter, Rando Cheapo Amazon filters. I OEM paper filters. I can't tell a difference between any of them in terms of power, the power gains these things are giving are 5 horse power at most. You really cannot tell the difference.. I prefer filters like the AEM or K&N because you buy them once, and rarely have to clean them. Just one less maintenance step you have to worry about....
Great video. Im interested to see these tests after washing/cleaning them.
That's a great suggestion! Thanks for watching
I’ve seen used cars for sale that came back from Saudi Arabia. My bet is that the sand has done damage to their engines and they are dumping them before the issues really devalue them 😮
It looks like Spectre raised their prices. For my Tahoe, it's almost as much as K&N. I've used K&N filters for years with no problems. I don't drive in dirty conditions and I clean them regularly.
Great content .
Thanks a lot! Glad you enjoyed it!
Great video! Could you also test other filter brands like Carquest premium, Fram drive, Fram titanium and Fram ultra air that I just recently seen at Walmart and is supposed to be Frams best engine air filter. Would like to see how that compares to the wix and purlator. Can you also test cabin air filters and engine coolant and windshield wiper fluid and brake fluid for future videos? Love your videos, keep up the good work! Also could you possibly go back to oil filters and test by pass filters?
got a new F-150 4x4 4.9 engine got 12/13 mpg on highway at 65 mph, after warranty put high pro cat, 3 inch exhaust with cherry bomb and K&N filter mileage went to 18/19 mpg and yes it pasted smog in california every year for 21 years i had it, see back then the computer did not control the air flow or gas intake like today's vehicles do it had had a carburetor no fuel injection on it in 1984 that was added in 85 or 86 but they had to stop using the 4.9 L/300 CID would not pass smog a few years later
Need to do a dyno run with no air filter for a baseline number. A difference of 1-2 HP is insignificant because of too many variables that need controlled. Engine temp, fuel temp, air temp, atmospheric pressure, humidity, and tire temp are just a couple that need to be the same for each run.
You can blow out paper filters with compressed air, or even bump them on concrete if you don't want to replace them every time.
K&N has always had competitors. Uni was the way to go for motorcycles.
Awesome, great video. Thanks for the effort. No more k&n performance. The aem is made by k&n you would think it would be the same as the select. I believe specter is made by k&n also?
Thank you so much. Glad you enjoyed! I've seen conflicting things regarding Spectre being owned by K&N I just know they were in a lengthy legal battle against each other. Thanks for watching and supporting us!
I’d be curious about the AFE dry flow filters. I have one in my car and my truck. Seemed to make a slight difference over a pretty clean OEM air filters that had fairly low mileage, Subaru and Toyota.
I have used k&n for over a decade but I almost never buy a used car that has a k&n filter installed. K&N may not be the best but they are good if properly taken care of. The problem is the k&n is either not cleaned regularly or of they are then they get over oiled. If the owner can't properly take care of something as simple as an air filter then you can almost guarantee that the whole car is probably not properly maintained.
As far as k&n performance I might use it at the track but for every day use the normal k&n is what I will always use.
K&N sells an oil spray which allows you to evenly coat the K&N and this prevents over oiling. It's also a lot quicker to apply because with the old way, you'd have to stand the K&N up straight and then apply a little bit of oil to the tops of the pleats and then let that oil run down the filter slowly but this takes a long time. Now, you just spray the cleaned filter until the whole filter is red and slap it back into your car. I haven't had an over oiling issue since I switched to the spray.
@@PeTroL420 Your missing the point. You are capable of not over oiling your filter with the new spray bottle. Thats a good thing. Not everyone who buys a K&N and attempts to clean it has this much skill. Remember, people are idiots, and Joe Biden is president. Proof
no one really washes or oiled these kn filters lol
Lol That's probably true! Thanks for watching!
that's not true. regular interval for cleaning is 25-50000 miles. You don't have to clean and oil often, but yes I for one absolutely clean and oil my K&N air filters.
If you allow more air flow you also allowing more dirt to pass. It’s a give and take. For daily driving just stick with OEM.
Incredible hair mod on this guy
Thanks! It was on sale at Amazon.😂
I run an oiled K&N. But for the price, that Spectre filter is cheap enough to be a disposable, with all the benefits of a performance filter.
Indeed haha. The Amazon prices were indeed higher though so make sure you check out Rock Auto. Thank you for watching
There's a lot of room in some air boxes. If they just made the filter thicker, it could filter better with more airflow.
Would like to have seen them compared to an OEM filter for a baseline
How many times did you redo the dyno for each filter to dubble check values?
You say that dust larger than 1 micron, but how much larger? As long as it's not too large for the engine oil to encapsulate it, it won't hurt your engine. Although you might want to change your oil more often when running a K&N.
Personally I've been using K&N oiled filters in every car that I've owned since 1988. Most bought brand new and over 100k miles later zero internal engine problems and no oil consumption or smoke.
The cleaning kits are about 50.00 got to figure that in...
Good point! The cost of the cleaning kits is definitely something to consider. Thanks for mentioning it!
I was thinking 🤔 that in the future cost 💲 😊
My K&N cleaning kit was about $15 the last time I purchased the kit more than 12 years ago. Now, the price has somewhat increased but still far below $50, and I still have plenty left, and thus, it will be perhaps another 5 to 7 years before I will need to obtain another cleaning kit. If you paid $50, I know of someone who got royally ripped off. I clean the filter about every 30,000 miles. Other than a Honda Accord Coupe, all of my Toyotas and Lexus vehicles have never used any oil, up to one vehicle that lasted 212,000 miles before a young lady rear ended me and totaled the car.
That's not true. The cleaning kits are less than $15...you don't know what the hell you're talking about
20$ at Advanced and that’s overpriced.
My service manual recommends the engine air filter change every 4 years or 80,000km (~50,000 miles). Every 6 months? Maybe in the desert. Comparisons should be realistic.
I think weighing the filters after sending a fixed ampunt of dust through them would have been a more useful way of determining the holding capacity of the filters. If 75 grams of dust is sent through and almost all of it goes right through the filter I wouldn't really call that number the filter's capacity. Comparing the weight of the dust sent through to amount the filter actually captured would have been better I think.
Great test
