I have about 50K miles across 2 bikes using K&N, so I'll be sticking with them. But honestly I think most of those filters would do the job just fine with regular maintenance.
When referring to particle sizes in regards to oil filters, it is important to realize exactly how small the particles being discussed really are. Then, we can discuss the filtration effects of the filters in question in regards to engine life. There is a misconception when it comes to oil filters, that the smaller the micron rating the better the filter. Some companies rate their filter as a “5 micron” filter, which means the filter will catch particles microns in size with at least 50% efficiency. Let’s put a 5 micron particle in perspective. 1 micron is .001mm (or .00003937 inch), so 5 micron is .005mm (.00019685 inch). The tolerances in your engine will be no smaller than 2.5 thousandths of an inch (.0025”). So, 2.5 thousands of an inch, which is equal to a 63.5 micron particle. A 5 micron particle is smaller than a human red blood cell, and too small to see with the naked eye. So how can a particle that size cause damage to your engine?
Next, let’s consider the purpose of an oil filter bypass valve. A bypass valve opens when the inlet side of the filter gets too restrictive. This can happen when the engine is cold and the viscosity of the oil is high (due to the weight of the oil), but this primarily happens when the filter media gets too restrictive or clogged. This is done to keep catastrophic engine failure from occurring; dirty oil is better than no oil. The lower the pressure relief rating, the sooner the valve allows unfiltered oil to enter your system. The last factor that contributes to the bypass opening is the amount (surface area) of the filter media used in the filter. A filter that has a high surface area is going to hold more contaminant and promote good oil flow for a longer period of time, so the bypass will take longer to open.
If the filter you use is 95% efficient at 5 microns it is going to remove more contaminants than a filter that is 3% efficient at 5 microns. The question is, how long will it take for those filters to load up with contaminant and enter bypass? The answer is simple, the more efficient filter will load up sooner, but at what expense? Oil flow is necessary to lubricate rotating parts, prevent engine failure, and help keep the engine cooler, plus again dirty oil flow is better than starving the engine of oil completely (the theory behind the filter bypass). Clean oil is best for long engine life, and a filter that can promote clean oil flow consistently for a longer period of time is a key component of any healthy engine.
When you are talking about filtration, whether it be oil or air, there is a balancing act that has to be performed to ensure your engine gets the protection it needs while giving your engine the most flow possible. Unfortunately, when the focus is an oil filter that is catching extremely small particles at a high percentage, the tradeoff is flow rate. This put the consumer in a “Catch-22” situation. Do you use a filter with the most efficient media at the smallest particle rating, and have the bypass open letting unfiltered oil through the system? Or do you have a filter that does not filter as small a particle size, but filters more of the oil for a longer period of time? K&N filters are designed to give you the balance of oil flow and filtration. Of course, we would like to say we have the most efficient filter at the smallest micron range, but the fact is we are not going to sacrifice oil flow or the quality of filtration by having a high efficiency filter that operates in bypass mode for 80% percent of its life. I know for me personally it’s a simple decision, the small particle filtration does not mean anything to me since we are talking about particles I can’t see, especially if there is a remote possibility of unfiltered oil touching my bearing surfaces causing premature wear and eventual engine failure.
When you are comparing filters, to make the most informed decision possible, look at the following things (with the least amount of emphasis on micron rating): Filtration efficiency, Filter surface area, bypass setting.
The KN-171 filter has a nominal micron rating of 25, meaning it will capture 25 micron particles with at least 50% efficiency. The filtration efficiency of the KN-171 at 5 microns is 3%. The KN-171 also has 165 sq.in. of filter area partially the reason it flows 25% better than the OE, paired with a bypass that opens at 14psi. The Harley Davidson filter 95.8% efficient at 5 micron and 98.6% at 25 micron, it also has 63 sq.in. of media and a bypass that opens at 10psi. This means the Harley filter will run in bypass mode for a significant portion of its installed life, whereas the K&N will allow oil to flow through the filter for a longer period of time. In my personal opinion, this makes the K&N filter the clear choice.
Here is a side by side to the amount of media inside of a K&N filter and your typical OEM filter (I don't think it is Harley's current one but look cool)
Amazing information !! 👏
It looks like the amsoil filter is very close to ome 98.7% @ 20 microns . Though watching this it felt like the K&M filter was the best choice and after this info ...still does.
I personally don't care too much. I'm a guy who religiously changes oil at / before specified intervals.
My '19 RKS had a stock HD filter that was cranked on way too tightly (either by the motor company, dealer, or previous owner). The touring line has the filter in a small pocket in front of the motor with VERY limited access. Needless to say- I had a difficult time removing it after it crushed using the HD oil filter tool.
I swear by K&N oil filters. Having the integrated nut on the end of the cannister totally prevents the cannister from crushing.
Agree 100% this is why I try to fit the largest possible filter on all my power equipment. Today not only are they trying to sell the public with the lowest micron rating there selection is also shrinking literally, in choices and in physical size in order to accommodate many more vehicles with that specific filter this adds to the detriment, one size does not fit all, having a larger filter area is always better, with a sensible micron rating and the highest psi. bypass valve rating that is acceptable to your application. But I seem to be repeating myself over and over with the lack of emphasizes in these oil filter video's on the importance of the location of the bypass valve which should always be direct, oil should not have to pass over the dirty filter medium before re-entering the engine and in this video the only filter that offers that is the Wix. Being an old experienced gearhead It is unfortunate that through the years for the sake of keeping manufacturing cost down and staying competitive many companies are no longer producing them as they once did but don't worry there are one's that still do and are these are the ones I seek. In sum todays trend seems to be smaller filters, (buying the public) with the lowest micron ratings, and no direct bypass valve. Ridiculous. Hopefully this trend will change with people understanding on how often these bypass valves are being activated with all this at play. Look harder and shop wisely, sincerely, old gearhead, Paul Timpani
Any thoughts on using a Fram ultra 3600? Bypass is 12 psi.
Thanks for this. I will continue to run K&N as I have for decades. For the record I have never noted any collapsing of the internal support cylinder on the K&N filters I run. I do cut them open quite often just to have a look.
Again, love that can opener! Very cool comparison Brad! Impressive amount of surface area in the K&N.
You had me looking at oil filters for 26 mints.. good job .. keep it up.. 👍👍👍
Thanks 👍
Great video Wizard! I really appreciate this level of investigation and exposure man. I’ve always used Wix & K&N filters and you have now assured me that I’m using good filters indeed.🤘🏼
👍
I have watched vids that seem to prove claims that Hiflofiltro manufactures the filters for K&N. The model numbers are even almost identical for the various applications. I have used K&N filters on most of my engines, but just bought a Hiflofiltro HF171BRC long filter for my next M8 oil change and saved about three bucks.
Thanks for doing this so we can make informed decisions.
I have always used Wix oil filters, but thanks to your diligence, I'll be switching to K&N. Thanks for the video.
👍
Always been curious what made the K&N different (not necessarily better, but it's certainly different). Thanks for your time and effort on this one. Fascinating comparisons.
I know this video was two years ago but thanks for taking the time to make this video. Good info.
Thanks. I apreachate it.
Looks like K&N it is!!!
Just ran my new M8 road King to 500 miles and I'll be changing the oil with the K&N filter with K&N. Also be using those filters for the life of this bike. Good video. I have a good understanding of filter media and benefits thereof, K&N guys. The bigger holes allowing free flow! That's huge for the M8.
K&N
Great video . Thank you for taking the time to produce this video. Awesome information I was completely entertained and remained interested throughout. Somehow I wound up on your channel. Glad I did and subscribed.
Th Thanks for the complement!
Man that is a great video the best oil filter video on RUclips make sure you clean up that mess the service manager will Yell at you
K&N and Hi Flo brand filters are the best money can buy imo...never had any issues with either one
😮 awesome video K&N looks like the way to go
Awesome video once again, keep up the great job you’re doing. I’ll continue to use the Harley filter, just due to the simple fact the media looks really good regardless of the length and the holes for the inlet on the face plate for the oil are way bigger.
I agree. I prefer the HD filter also.
my dealership never knew anything about the new oil filters until i tried to buy a couple. They are backordered until at least the middle of june.
👍
This is a really good video. Well done Brad!
Thanks for the compliment!
Awesome video man, thank you! I was really curious about the new Harley one, that some say will help with the sumping issue with the m8. Wish you could test the flow rate.
I use hi flo reusable oil filters great oil flow with heat sinks to aid in cooling. About 10° cooler.
Great vid, answers questions thanks. Just subscribed.
Thanks for the view and comment!! Welcome!
Good video. Learned a lot.
GREAT JOB! THANKS!
Thanks for doing the video. Very interesting. Stuff that I like to see. Just from what I understand the Harley Davidson new M8 filter has a higher flow rate that would probably be the only difference. Thanks again for doing the video.
K & N the most surface area to catch particles
Thank-you. so interesting, i subscribed immediately. I hope you grow good in RUclips.
I appreciate that!
Thanks for pointing ☝️ out the updated Milwaukee 8 oil filter . I’ll be looking for it at my next oil change !
No problem 👍
The OEM M8 filter relief valve spring is a higher value. Harley found the TC filter valve was opening too early thus bypassing unnecessarily. Per Harley-Davidson Tech services.
I have four HD's and have been buying K&N's in bulk. Think I'll stick with them. Very nice comparison.
Isnt that crazy how much more filter media they cram in there. I was shocked. Thanks for the comment and view!!
I’ve always used K&N on my Harley’s. Can never go wrong with them
K&N and hi Flo are the best money can buy
Thanks for taking the Time to Demonstrate ,, Seems both the M8 filters provide better flow than Previous ones and although it says the new one has %25 increased I'm really not sure if it will actually be of any benefit..As for the filtration element I think due to material and less length compared to KnN it would still filter and flow better and more free..Jus my thoughts.
👍
Thanks 😊
Hello Brad I enjoy your work What I like to see the first 1000 miles service on a touring motorcycle like a Road Glide Cause I have one Thanks Bill
Thanks, will do!
Devils in the details! Thanks bro. Good video
The most important thing is oil changes at proper times. The best filter will not preform as designed with breaking down oil.
K & N for me, believe they are a better quality product plus have one extra advantage over the others..... the welded nut to fit and release them, works so much better than having to have a special tool that often slips
Harley seems to come it with new engine items every 16 years with mult revisions once new engine arrives. New oil pumps, new filters, repairs for oil transfer. They they test stuff before release. So many other manufacturers offer new stuff every year without all these recalls/revisions.
I’m sold on the K&N just because of the metal body. For shure it allows more oil than the HD
👍
That blow by valve concerns me. I like that on the new M8 filter you said the bypass valve spring was stiffer. It seems to me it will be less likely to open that bypass valve and flush the filter into the motor's oil supply.
Good video
Thanks.👍
Old filters since the Evo days have had a 8-11psi bypass.
I’m guessing Harley finally upped it to around 15-18 psi since the oil pumps from even the TCs put out a lot more psi which would cause the lower setting filters to go into bypass more often.
Bosch 3330 (short) and Bosch 3342 (longer)
would be my go-to if you buy in bulk or need one easily sourced.
I will continue to use OE filters. I have run an EVO to nearly 100,000 before I rebuilt and a twin cam 88 to over 100,000 and it is still running great with engine never having been apart other than cam chest changing to gear drive cams @15,000 miles. I now have a TC 103 and an M8 107 and have always changed the oil @ 2500 mile intervals so bypass should not be an issue. It's a formula that is proven for me. The K&N looks great but I feel it is overengineered and offers more protection than I need so why spend the extra money when I've never had an oil or lubrication related failure. I have also only ran Amsoil or Redline oils.
Stamped sheet metal stand off and plastic valve are to cut cost. OEM filters used to have a coil spring stand off and spot welded all metal valve. Cut a FRAM you'll be surprised.
Very informative, love your videos! I’ve always used K&N on my 2017 ultra and getting ready to do the 50,000 miles service. After watching this I will remain using them, that media was impressive 😎
It sure was!! Thanks!
Another very informative vid.... any comment on why the H-D and WIX use a bypass valve but the others don't?
The K&N and Amsoil actually did have bypass valves but there were inset on the bottom of the filter and I forgot all about them because there hard to see. Good eye and thanks for bringing it up.
@@HarleyDavidsonWizard TY sir... wasnt aware of the possibility of the valves being inset. Good to know! Love the vids.... learning a lot!
Very good, I always buy Harley filters. I figure they built the bikes, they got the flow, and the filtering figure out to protect their bikes! Just like the M8, they increasing the size, theirs a reason.

I saw that video a couple days ago. I had not seen a fram Harley filter before. Both filters he cut open are for evolution engines. I wonder how different the fram & HD oil filters are for twin cam engines..
@@HarleyDavidsonWizard I've been using a Fram PH6065B on my 2000 FLHR for years. I also use them on my FLHTCUSE7. Mobil 1 Twin Cam Synthetic and Fram oil filter. I use Amsoil Shock proof in my gear box.
The K&N filter is an older, paper filter technology, this filter blocks particles on the surface. The H-D, Amsoil and Wix are using a multi layer media that traps particles within the layers similar to a HEPA filter. The multi layer approach has proven to trap more before clogging while providing better flow through.
You can't do a comparison test between filters if one is wet with oil in the other is dry
@@scotthines4326 nobody made any comparisons here about efficacy of the materials. I commented on the type of filter materials, which, when observing the number of pleats and visually comparing the difference in overall surface area of the materials is comparing apples and oranges, for the reasons I stated.
No mention of the lack of bypass valves on aftermarket filters
Interesting, interesting, interesting.....
That's about all he has to say.
Brad, while watching this excellent video I thought it appeared doubtful that the new M8 filter had 25% more surface area, so I did the math. (Sorry to nitpick but there's a minor error at 5:15 in your inch to mm conversion.) Based on your measurements, the new filter has 17.5% more media surface area at best. A 25% increase certainly sounds better but it just ain't so.
I was hoping someone would do the math. Just by looking at it, it doesn't look 25% longer or anything IMO. Thanks for noting my error. I checked it 3 times lol.
It's wider so it doesn't needed to be 25% longer.
Looks like 25% to me
Awesome video! I have a 2019 Iron and it calls for the twin cam filter. I went to Autozone and bought Lucas 20w50 synthetic motorcycle oil and filter. They didn’t have the K&N oil filter but crossed it to a Mobil M1-102A. 30 micron, anti drain back valve, 12-17 psi release valve. The only thing wasn’t at spec was the 5 micron which the Mobil had 30 micron. Would this filter be ok? Thanks for your expertise! I’m a certified Ford diesel technician 6.7l Powerstroke specialist which these truck only get Motorcraft filters. Keep up the good work man and just subscribed!
I wonder who makes the hd filter? Looks like Fram or wix
I bought a new 22 RGS last year( 2022) after a couple months I had the first service done.The oil filter they put on is 3 1/2 inches long I believe is the short one. So why didn't they put the longer one on what if what your saying is true.?. Can you measure the outside of the filters as if he never cut them open.. what are the lengths of both.. thanks
I’ve always used K&N filters for demanding performance 👍🏻 I assume all the other filters were synthetic approved?
Great comparison video.
Question: What kind of filter do you run on your bike and would you change it based upon your comparison?
I have a twin cam. So i will continue to run my black harley davidson twin cam filter. Ive seen a handful of twin cams with HD filters over 100k miles where Ive taken apart the engine and the parts are beautiful. These were regular dealership customers so I was sure the engines had not been torn down before ect. And every one had a HD filter. The comparison didn't change my mind. But sure was interesting. Id think about the K&N but I think the nut on the end of the filter is ugly and tacky. JMO
@@HarleyDavidsonWizard I personally like the nut, it makes it easier to remove.
I'd never use a disposable filter again. The better flowing, better filtering, better cooling reusable filters are far better. I've got 3 bikes and have been using reusable filters on all 3 for over 5 years. Nice to not have to even think about looking for the right filter for every oil change and not throwing used filters in the landfill
K&N now makes the longer M8 filter. $16 on Amazon.
SO, in conclusion???
Looks like the k n is going on my bike.
Many manufacturers going with cartridge paper filters vs metal enclosed. Less environmental impact. Just think of all the metal enclosed filters in dump.
I would like to design a reusable oil filter that uses a disposable cartridge type filter.
It seems as though the top plate may be controlling the oil pressure based on # of holes and their diameter.
Has any one observed this?
Thank you. I wonder the reason why they moved to a bigger filter, would it have something to do with Sumping? I have a 96 EVO which always had stock oil filters and they are long just like the new M8 oil filter. Then it's either the new M8 filter or the K&N I will put on my 2017 107 ultra. But I am still seriously thinking of placing a magnet at either the outer or the inner bottom. Would it be a dumb thing?
I assume the higher volume filter is to go along/work better with the new higher volume pump that comes stock on 2020 models. That's my guess at least. A magnet on the outside wouldn't hurt anything.
I would love to see a video of what pressure these oil filters go into bypass.
the lower the microns the sooner the bypass opens, 5 microns is too small per KB the best engine builders on you tube
@@waynetrainor654 yes, RUclips experts are way better than real engineers that get paid to study and solve oroblems! The problem I have is that I can find a RUclips video that agrees with whatever theory or opinion I have. Which one is right? Consensus doesn't mean it's right. Look at the doctors that said a cloth mask and the vax was effective against the spread of Covid. Neither was true. Something to think about. 🤟
Everything you did is informative but what we need in how well a filter filters. Construction is important.
There must be a way to check how they are rated for micron. Almost all of us changes the oil at the beginning or end of the season then store the bike here in the northeast. So fresh clean oil is not a problem. Riding about 5,000 to 6,000 miles an average season.
Membrane can filter differently.
Anyone have any ideas?
I would really like to test or be part of testing the actual filter capacity and efficiency. Maybe when the channel grows or if a situation arises I can get into a 3rd party testing facility. If any one has any ideas, toss them out there. I would be super interested.
Is the new twincam filter got a new prefix number allocated ?
Also I was watching a video by another engine tech and he was saying the issue with HD Filters is that the 5micons is too small and blocks prematurely and sends oil to bypass too soon in the mileage. Have you also found this. ?
Would it be better to have a 10 or 15micron to stop oil being pushed through bypass ?
Enjoyed your video once again.
Thanx Brad 😎👍
I heard that statement a lot since posting this video but I haven't seen any proof or videos describing testing and showing it. I would be interested to see a test like that tho. From my real life experience, the bikes I see that have 100k miles on them have HD oil filters and oil changed every 5k and there engine insides look beautiful and show zero signs of dirty oil or such. Thanks for the comment and view.
Great video. Whats your thoughts on reusable oil filers ? Thanks for sharing. Cheers.
I'm not a fan of reusable or cleanable filters. i've heard A human hair is about 75 microns across so if a filter is good down to 5 micron, I feel like there is zero chance of knowing (after cleaning a reusable filter ) if the dirt the filter had collected is cleaned out as I cant see it. And there always super expensive and seem to be constructed with o-rings that are going to be a pain to find when it comes time to replace them. The normal filter is just so much easier. IMO
Thanks Brad for taking the time to reply. I think I will stay with normal filters. Cheers
@@HarleyDavidsonWizard and way less messy!
Great video, question do you run different typres oil/fluid as in oil for engine and primary and transmission as amsoil makes trans and primary specific oil I have read you can use 20w-50 in all 3 holes but in my opinion I think it best to use specific oil for specific holes ? I have a 02 Dyna
I'm no expert but I run hole specific lubricants. Motor gets 20w50 trans gets a gear oil and the primary gets its own oil built for wet clutch application
@@gliderydin2911 Thanks and I agree different lube for different parts of the bike or car etc... I went with amsoil hole specific
K+N for me!
Or Fram 2nd
I use K&N on my 675R race bike and when i change the oil i never see residue. It runs between 9000 to 13,500 rpm
👍
The internals of the K&N filter look identical to a Fram.
K & N has best filter technology
Hey Brad I was watching Kevin on pro twin and he was saying that the 5 micron filter was only good for about three thousand miles then it started going through the bypass might be something to look at
, I listened to what Kevin had to say also and it made me decide to change just my filter every 2,500 miles. Not only will that ensure the filter never goes into bypass, it'll also give the old oil a fresh shot by filling the new filter with new oil before installing.

Your opinion means a lot to me I seen something and wanted you to check it out thank you and keep the videos coming!
HI-FLOTRU
I kind of think the Wix filter has the best quality.
Should have added a fram chrome filter to the list .
Ya I wish I knew about it then.
My kn 171c leaked all over the place. Checked the filter last after re torquing everything else. China!
the amsoil filter looked bigger / diameter where it bolts up to the engine ???
Too bad there isn't an Amsoil or K7N filter for the M8 engine, the longer style.
Go with K & N. Best quality
Hey brad
👍
What are your thoughts on these engines having a centrifuge and running a filter magnet?
In my opinion if there's enough steel material floating in the oil for a magnet to grab, the damage has already happened. Normal ware is aluminum and bronze.
@@HarleyDavidsonWizard thanks the reason I'm asking is because I just purchased another one of these expensive bikes and want to have some faith in it not breaking down and having it spend its whole life in the shop thanks again
I was helping my buddy do an oil change and he had one of those reusable oil filters. What do you think of them. I’ve always used K&N myself and really haven’t used any other filters
I'm not a fan of reusable or cleanable filters. i've heard A human hair is about 75 microns across so if a filter is good down to 5 micron, I feel like there is zero chance of knowing (after cleaning a reusable filter ) if the dirt the filter had collected is cleaned out as I cant see it.

5 micron is usually for fuel filters, seems very small for oil
It's overkill for oil. The filter media will plug up faster, forcing the bypass valve to open.
I'm glad you did this so I didn't have too, always wanted to know, now I do, after replacing thousands of filters on Harley's over 25 years in my shop, I will use the new longer Harley filter on my personnel TC bikes, the nut on the K&N looks cheap and tacky and filter is over priced, also I wouldn't recommend the Amsoil filter to anyone, and the Wix is for lawn mowers. thanks
👍
Studies have shown that harley filters are clogged at 3,000 miles and the bypass opens.

Thats bs
why didn't you check on a fram filter?
I didn't know the fram filter existed at the time.
What filter material used for 5 micron 95℅ efficiency media.
What is the life of filter after first change of filter.
Thanks but bottom line is which filter is best? Unfortunately scam city is ruling the world
I like the normal Harley davifson filter myself.
Unfortunate that you chose to evaluate used Wix, K&N, and Amsoil filters. Should have used 5 new filters for a truly comparable evaluation.
WIX DUDE !!
K&N wins! Oil filters and Air Filters, K&N always. Since my Shovelhead, EVO and several Twin Cams, always K&N & Mobil Oil. You realize HD doesn't make their fluids, filters etc...
👍
That's true with any manufacturers. John Deere, Caterpillar, etc. They have companies produce to their standards. If you read all his comments, high mileage bikes that he's seen have run factory filters. In my opinion, they all are good. Main thing is doing the maintenance. I am going to run the new factory filter for the M8, on my bike, though.
So now H-D fits a larger filter in order to (try and) flow more oil.... why don't they just address their quality of manufacture ?
The oil pumps and pressure relief valves are where the problem is along with too fine a filter......... the filter clogs too easily and then the oil bypasses the filter medium - result is unfiltered oil circulating - use a Sportster oil filter and the bypass situation goes away. Sure the Sporty filter doesn't filter to 5 microns, but neither does the 5 micron when it's in bypass mode.......
Thanks for the view!
i think the k&n is the winner!!!!
👍
You’re “about the same” and my “about the same” are not about the same… 10:30 those inlet holes are very different. 8 large on the HD vs 6 tiny ones on the Amsoil. That thing seems like it would be restrictive.
Wix!
My 99 built motor hates the K&N fikters
Why is that?
@@HarleyDavidsonWizard honestly I got no idea why it does not like them. But idle my bike idles low and lumpy 95" built with big cam oil pressure goes below 7 pounds with K&N filter.
They would not have changed it unless there was a good reason.
Harley increased capacity because they filter down so tight 5 microns. They know that their oil filters end up in complete bypass quickly ie. 2500-3000 miles. The Amsoil filter is a 20 micron filter and the K&N has a 25 micron filter. The amsoil and k&n won’t plug as quick so they filter more. Increasing the capacity on the Harley filter was to help prevent the oil filter from being plugged (restricted) so quickly so it doesn’t go into bypass and can filter oil longer. A 25% increase in filter media on a 5 micron filter won’t extend the filter life out to a 5000 mile oil change interval. It is better but, falls short. If you are going to use a filter that is that restrictive you should change it at 2500 miles in between your regular oil changes. With the amsoil or k&n you aren’t filtering as tight but your restriction is punched out to a longer time or miles window thus not going into bypass and still filtering oil all the way through your 5000 mile interval. Nothing wrong with the Harley filter, just know you need a filter change at 2500 in between the 5000 mile oil change. Maybe sooner.
regardless of how often you change your filter or how new it is the bypass valve will still get activated, such as when the oil is cold and doesn't flow easily or when your running your engine at higher RPM's, this happens more so with todays offerings of shrinking filter sizes, this is why having a direct bypass valve is crucial , sincerely, old gearhead, Paul Timpani
Mike, I kind of understand the micron filter and stuff. But I have a hard time swallowing that a filter could get plugged up and go into the bypass mode I am thinking that there would have to be a lot of particles in that filter in order for it to plug up and go into the bypass mode. I would like to see somebody do a filter presentation where we can see how much particles it takes to plug the filter up, then go into the bypass mode.
You need to have a close look at your number.. 5000 microns is nearly .2 Inches (.1968") That's nearly a 1/4-20 bolt.. And more ridiculous, 25000 Microns is just under an inch (.984"). Too many zeros in your post.
@@JHV166 I was wondering about that myself the numbers are just too high
@@JHV166 Jim yes. 5 micron filter. 5 5 5. I have no idea why I wrote that that way. 😂😂😂😂😂 Now that I have my reading glasses I can definitely tell you that you’re absolutely right. It’s 5. Talk about feeling like a blind old fat fingered bonehead. Thanks for clearing that up. At least my better half got a good laugh and a “ I told you to go to the eye doctor.”
What the hell is a Harley Davinson?
All this is OK, but it boils down to the word Microns,, one of the best harley builders states 5microns is too small and the oil will just bypass very soon. his initials are KB
Too bad you didn't include the newer Fram filters....Fram having basically gone back to the original Harley filter design form decades ago with better construction and heavier spring rather than the silly stamped sheet metal thingie the new ones have...
I didnt know they existed at the time of this video. The other fram filter video I've seen was for evo oil filters. I wonder how much of a difference there is with a fram twin cam filter.
This morning it was tare now its tear
I fixed it! lol
About the FRAM Harley-Davidson oil filters!
