- One of the most commonly asked questions in our service center is, “How do I clean my air filter?” In this tutorial, we explain the differences between oiled and dry filters, as well as how to clean and re-oil them. We’ve even created a free re-oiling calculator so you know precisely how much oil to use. You'll come across people online complaining about oil filters caking up their MAF sensor located in their air intake tube. This occurs only when filters are improperly oiled. In this video, we’ll show you the right way to do it so this doesn't occur. If properly cared for, your Ram-Air filter element should last years and years.

This is 100000% better video than K&N actual video
The French guy is so professional.
I thought he was German
oui
@@DB-qm4jx sounded german
Americans are such suckers for people talking with exotic accents
I had no idea the oil was the red part, not the filter. Great vid!
From here on out everytime I clean my filter, I will use this Accent
Thats funny shit man!
Having two Banks filters and alternating them between oil changes is a good idea for Banks too.
Come on everyone. Anyone you know that works on their own vehicles needs to see this. I am willing to bet that a very high percentage of people are way off on the oil amounts.
Excellent video. Much better explanation than what Ive seen elsewhere. One comment, The new K&N oil bottles, that I just received today, do not come with the volumetric graduation on the side. This caused me to mess up on my first try. I ended up dumping the bottle out and putting a measured amount back in. But with no visual means of telling how much I was putting on, I found I emptied the bottle after only going around 1/3 of the way. Consequently I had to re-wash and now waiting for it to dry. But my car has two filters so on the second filter I speed up the application and did every other pleat. With every other pleat oiled I continued on to the pleats in between and ran out just as I competed the full turn. Doing every other pleat helps keeping from over oiling, as shown in the video it will wick quickly to the rest of the pleats if you run out.
The man doing the oil knows - if it is clean and dry, the oil will wick and spread. I like how they know the volume of oil for the thickness and surface area of the particular filter. Use of time and gravity too - Excellent!
Thank you - Banks leads the RIGHT way again
Thank you! Very useful information.
Also, I love the French-american accent. 😁
Merci beaucoup !
The aerosol oil can is the way to go. Always easy to properly reoil
Throughout the years I had both dry and oiled filters. Truthfully, I didn't see a difference in performance one vs the other. Than again, I'm not racing my trucks at the track. The oiled obviously requires a bit more attention. It's also not a bad idea to have a secondary filter to throw in interm, while the other drys properly.
first time I cleaned my oiled BANKS filter I was online ordering a second one with a spare sock. Hot swap durring an oil change and washing the filter at a later date is alot more convenient.
I'd like to see the numbers, buht i'd put money on oil filters having a higher micron filtration level to them. Keepin the finner dust out of the engine
@@markleppington2860 no doubt the oiled will catch a lower micron level.
@@paulbenderavich3833 Very true however, they will also get dirty faster and require cleaning more often. It goes with the territory.
@@markleppington2860 it's less to do with the micron level and more to do with the oil actively grabbing hold of particle contaminants, think of it more like the modern day take on an oil bath air cleaner
Thank you. Nice explanation and demonstration.
Glad you liked it, thanks for watching.
This is a really interesting and helpful video. Thanks for sharing it.
I use the spray can of oil only spraying the outside of the pleats. It wicks very well.
Great stuff guys!!
Ace vid. Thanks, guys!
Great content!
I do this by applying oil across the length of every pleat, start to end. The nozzle of the oil bottle seems ideal for this. It's a quite easy process. If you increase boost, you can use sensors across the air intake path in order to measure the pressure drop at every stage. If your OEM filter proves to be too restrictive, I am in favour of an aftermarket like K&N. Caterpillar marine engines use such filters from the factory. But if you drive in dusty/desert conditions, maybe better stick with OEM filter and change more often, before pressure drop becomes too much causing increased fuel consumption, reduced performance and sucking turbo cartridge oil in the intake.
What do you mean by "pressure drop?"
Awesome, thank you! When is the Derringer coming out for the 2012 Cummins?
Actually did this a few weeks ago on my Banks oiled filter for the first time. Glad to see I got it right, but it's not that hard to do. I might have to look into that pre-filter though out around the farm.
hands down much better, all the large debris and bugs never get stuck in the pleats anymore. I wouldn't go back to a filter without a prefilter sac
This was very good video thank's !
Very informative!
Thank you for that I didn't know about that I always covered with the airsoft and the same stuff you guys have tab and head way to my toil on it but I don't understand you and I'll do that to my next Winter good job
Make sure to clean your MAF after a few 100 miles with a wet filter when first installing or re-oiling. Found that out a LONG time ago when i first installed one on a Supra i had back in the early 00's. My throttle response was off and MPG in city driving was poor. Checked for intake leaks and noticed the intake runners had a very light film on them, traced it back to the filter and cleaned the MAF fixing the issues.
What does the mass air flow sensor think about these filters?
When are you guys going to make a cold air intake for the 2018 f250 6.2?
helpful info thanks
Cool video thanks!
Very helpfull, thank you.
Thank you for that
if you are oiling your filter i strongly recommend putting the oil in a paint gun and spraying it as if you are painting . Much easier , more even coverage , faster and you measure beforehand so you can just spray until empty .
14👍's up Mr POWER thanks for sharing
Have been member since 2000 used in jet ski and 4 banger Honda and F-150 10th generation V8&V6 and Ford Explore V6 and motorcycles and dirt bikes 💯🤙😎💡🔥 Best lasting product
If you live in an area like mine I would highly recommend finishing the cleaning by dunking the filter in deionized water or else you will build up minerals like calcium and iron over time ruining the filter.
makes sense actually, same reason why you should put distilled water in the rad n not the well water
Very true...distilled water is now very expensive so the cost of that needs computed into the maintance expense. Maybe a 1 gallon jug of drinking water will work.
You must be in FL. So what I do is pickup a RV water filter from Walmart, attach it to my hose and it removes all the calcium and iron.
Dunk it in water, then throw it in the trash. Oiled filters let so much crap into your engine
Lols…work!
I use aerosol chain lube. It's oil & a thinner that evaporates.
The cheapest I can find.
So what would good time or distance intervals be for someone who only drives 10K a year and the vehicle has 7K on the vehicle from brand new?
Environment - mild-moderate - No desert.
I'd like to see some actual tests comparing oiled and dry filters. Diff cover stylee
i can see @projectfarm doing this, he's already tested reg filters to KnN. I feel the difference will be oiled filters may trap more dust on the micron level, verses dry filters
@@markleppington2860 it was actually the exact opposite. Oil filters let more dirt through on all levels
Most modern cars do not like oiled filters. The suction created by the engine through the filter pulls oil through and coats the mass air flow sensor, messing up its ability to read correctly.
Not to mention it’s far far easier to maintain a dry filter.
@@definitelydipper595 i think youll find thats by design and part of the job of the 'closed' pcv system to regulate the blow by
@@Bunna08 this has nothing to do with PCV systems.
I’m talking before any of this air enters the engine, it goes through oiled filter media, pulls oil through the filter and coats the mass air flow sensor, hampering it’s ability to read correctly. Which usually means it ends up running way richer than it should.
I have DNA filter in my bike. Is it alright that I use a K&N kit to clean and oil it?
I dunno what’s in the K&N air filter cleaner but it smells, looks, feels, and cleans exactly like Spray 9. I’ve used spray nine to clean all 4 of my K&N air filters for well over a decade now. Works great and is much cheaper then the K&N branded cleaner. Always use the. K&N oil though.
Never really compared the two. What is better and why??
I have a filter like this on my motorcycle but the one on my truck is stainless steel not paper, wonder how I clean that one?
I like doing a distilled water final rinse.
So I own two BANKS oiled filter and the prefilter sac, because I prefer to hot swap every 25k (km). cleaning large debris and bugs got way easier with pre filter.
but I have questions/comments
1: what happens if you over oil (just more restrictive?)
2: it'll be hard to explain, but I utilize that little lip on the KnN oil jugs nozzle. Place it inside of the pleats with the oil hole ot the edge of the pleat, than depending on the direction of travel, turn the bottle slightly so you barley drag rear of the lip against the pleat with the leading edge off the pleats as it will catch the mesh if it touches. This lip KnN provides on the bottle makes oiling each pleat individually a quick motion and fast to do.
3: I'm commenting before I investigate, but dose the calculator have BANK filters pre loaded?
That pre filter also robs horsepower. Had one on my quad but took it off and it flowed way better.
@@JimmySeahawk i don't find it dose, i'm not turbo'd or supercharged, and the BANKS high ram kit in my truck seems to be more than efficient. plus the socks fairly clean and isnt so fine of a mesh i feel it'll add that negative of results. buht end of the day if it dose rob hp i'll still take it over the lil hp gain without, any day, it simply makes cleaning soooo easy
Thinking of moving away from oil. Never feels like I get the right amount of oil on it, too much or too little, and then it gets on the MAF or creates more soot at the throttle body. Edit: The calculator is cool! The k&n kits I used to use were spray can or bottle and didnt have those markings.
We created this video just for you. Give the Re-Oiling Calculator a try! bnks.pw/oilcalculator
As long as you let it dry, and don’t put too much oil on the filter, it won’t effect any sensors
I’ve had a Banks oiled filter on my LB7 for about 14 years. I do have a spare one that I rotate once per year. I’ve yet to replace the MAF sensor. Over oiling will mess up the sensor so I’m told. I always let the freshly cleaned one sit at least overnight and wipe out any excess before it goes back on the truck.
I always take a cloth and pat down the filter media inside and out after to absorb any extra.
Does Gail know your walking around that beautiful place with those dirty filters haha. Get outside ! All jokes aside good video.
how does extreme cold weather effect the filter oil ability to trap dust ? is it still effective at -20 f or is a dry filter better ?
It will work, oiled filters are good for temps of -20°F or -28°C.
What is the substance of the filter cleaner? it smells like window cleaner the one i have. Maybe its the same?
Would the calculator worked with K&N panel filter too?
yes, it's just figuring the surface area using basic geometry. How they figure the oil amount/area is their secrete.
2:22 scared the hell outa me thought my fire alarm was going off
Awesome cleaner from the dollar store or home Depot is almost the exact same as the k&n cleaner
Damn I didn't expect such a heavy French accent it took me by surprise
my filters have so much gunk in between them… did the cleaning process 3 times and there’s just so much inside between the filters. should i just buy new ones?
If that is the case and you cannot get them cleaned, it would be to purchase new.
Remind everyone switch back to paper filters. I watched a comparison video with a particle counter and the quality paper filters block far more fine to medium particles. I'll give up 5-10 hp to help my engine last longer. I used to buy K&N filters as random middle of the year gifts.
Yep, OEM branded filters all the way. Dirt cheap on Rockauto, easy to replace and awesome peace of mind.
Of course that all goes out the window when you start doing aftermarket cold air intakes.
My favorite filter is a is a paper OEM style and always will be because the oil saturated filters clog up too often
I'd never heard of an oil air filter and watched this in April. Thought it was an April fools at first
Good recommendations.
There are a few automotive technicians who will tell vehicle owners not to use the oil impregnated filters because they have effects on MAF sensors. Sounds possible but is it likely to happen?
only is its over oiled. vehicle dependent too. depends on where maf placement is most of all
It also let's more dirt into your engine. All laboratory tests confirm this
Yup
nothing a little brake cleaner won' solve :)
@@mplewp or you can just keep a paper filter and you don't have to worry about it at all
The oil can get on the map sensor. I will run it dry the difference is minimal
Your MAF Sensors will thank you for the Oil.
Never understood why you would oil a air filter. They clog up cause of the dirt mixing with the oil?
Well done
Have you ever tried to pull a vacuum through the air filter say 24 hours after it has been oiled ? I keep hearing how the oil from the air filter can get pulled into the intake and fowl up the mass air flow sensor. When i say vacuum I mean the maximum cfm's at full throttle for the type of motor it is going into. Does this happen or is that just something the competition says?
How about if I have a drop in k&N filter? How do I oil those
Same way.
I am a fan of Banks products. I would like to see a video on how well there air filters actually filter out dirt. Especially compared to the competition. I am concerned about using any cleanable filter for a long term daily driver. I used K&N on previous vehicles and ended up throwing them away. I felt like they were just dusting the inside of the engine. I ended up going back to OEM paper filters.
Oil analysis showed no additional solubles or dirt or dust when I switched. I run oiled Banks.
@@TonyLasagna I've watched actual testing and the oil filter failed to stop any micro particulates throw it the trash
if you offroad just get a snorkel, way better than my banks i had and it lowered temps. On road the banks was great tho
@@triplestangman interesting let me see that
Some advice, as with me my oiled filters get filthy/grungy bad i had recently taken mine into the kitchen sink with Xhot water and soak them in dawn and dunk up and down you’ll be blown away how much grit/fine sand is trapped in the filter, especially when you never done a deep clean I was blown away by how restricted it had been my filters are 10+ years old…and to the guys that swear by OEM paper filters i get it but I haven’t had to spend $15-$20 a pop in years!
This just re-enforces what I think about gauze air filters. Paper disposable ones are easily replaced. Pretty much everyone I know who has a reusable one drives around with a half plugged filter most of the time. Nobody feels like cleaning their air filter.
Not only that, the gauze ones let tons more dirt in. Useless.
@@t_c5266 depends on the filter media and the density. I have an Airaid Synthamax filter. It is rated for 4micron. It is a cone filter. It is a larger filter while filtering like a stock unit.
@@mikekuschka998 If its rated by the company, it can be considered a moot point until lab testing is done by an unbiased 3rd party.
I also tried to look that company up and verify your claim, the only reference to filter size is on their wraps, not the filters. and the specific "non-woven synthetic" doesnt have any readily available info on it either
I am agreeing with you. I have a dry AFE filter on my Corvette and the inside of the air duct down stream of the filter is filthy, so it’s not filtering. I’m trying adding an oil foam wrap as a pre filter. At least the Corvette isn’t a daily driver.
You guys just can’t take care of their car’s
You are from northern France
Warm dawn soapy water. Water running in the reverse direction of the air flow. Not to hard as to mess up the gauss. Let it fully dry overnight as ya sleep. Then re oil and re install. Blue dawn soap then warm to almost hot water running backwards through it... darn things will look like you just bought it new every time.
I have a banks air filter on my wrangler, i liked it until i got more into offroading. Dont get a Warm Air Intake if you offroad around water. I went back to stock and added a snorkel with a prefilter(true cold air intake), does way better than the banks i had, had to constantly clean the banks. Banks was good on the road tho.
How often should you clean and re-oil? 10k miles?
That's what I'm wondering as well. 7.5k?
I like the guys who clean em once a week.
Give it time ,your rings and valves seats will thank you for putting them out of their misery.
Yes,you can clean your air filter too much.
My mechanic told me to never use the filters that need to be oiled because the oil will destroy some sensors over time. Any thoughts on that?
If properly oiled, the air filters will work just fine. We generally recommend the oiled (red) filters over dry (grey) for two reasons. One, slightly better flow characteristics. They are somewhat thinner, more robust filter material for the oil and can grab more debris. Two, the service life. The oiled (red) filter can go up to 30k-40k miles before it has to be serviced (dry is about 25k miles). Either filter will last until about 100k miles.
For those wondering that the K&N filter is terrible... this type of filter is recommended not for daily purposes although it can be but for performance in the race track or youre just trying to beat someone at the light. I recommend wix for daily trips to best protect your engine. It will affect performance over time as it does clog. Cotton gauze can filter pretty good until you get into micro dust particles. Not ideal for offroading. You can gain hp using the K&N filters. It will protect pretty good while even fully clogged without affecting hp. The oil is the key protector of the filter. This is not a filter for the practical driver this is usually for someone who's serious where each bit of hp goes where.
K&N: Marketing geniuses.
Oui oui 🥐
What happens if i dont oil my filter
I would never use an oiled gauze filter on an engine that uses a MAF sensor, esp a film style MAF.
After i did a lot research ,found out this looks very cool to have ,however no one will really clean and re oil their filter , given that it has the oil ,it will attract a lot more dust for sure but get clogged a lot easier, also i found out that a very very small amount of oil will go thru the intake and will affect the MAF sensor , so no ,not worth it.
lol i had k-n on my 2011 dodge journey traded it in with 70k on it for my 2014 journey so i pulled the k-n out of my 2011 at the dealership and installed it in my 2014 and have 140 k on it as of now, and yes i clean and re-oil every 20k miles and never had any problems with sensors on either of them...i also use the k-n cabin filter as well on the inside saves me a bundle as them cabin filters are a big rip off anyways
👨🔧So which filter is more beneficial...dry or oiled
We prefer oiled because, generally speaking, they offer superior airflow and dust collection.
@@bankspower 👌
Great video, id recommend buying dry filters like AEM or injen, its more reliable and no hassles.
Wish I had my filter to try this, my cold air intake has been on order for months for my 2020 Duramax!! 🤬
I didn’t know it was that hard to oil a damn air filter
A K&N still flows with a sixteenth of dirt on it.
It’s a great video as far as how to goes but for us consumers is a pocket drain. So I actually bought a 2nd banks dry filter so I can swap them easier between cleaning. $ well spent I guess?? But the least you could do is tell us how to properly clean it ourselves without having to fork out more $ on the K&N kit. The cleaning solution can be such a big deal. It actually smells like a lot of the cleaning liquids out there. I’m sure someone will eventually figure it out. The point is that one bottle of 32oz of K&N is barely enough to properly clean a Bank’s monster air filter. By the time I get done 2-3 rounds my finger hurts from that stupid spray pump and I can still see some small bugs in the filter…so it will never be perfect no matter how many times you clean it. But I don’t want to be buying all this cleaner crap from K&N which doesn’t even do the job properly. 🤷♂️

Oil filter will cause oil to collect on your maf sensor.
17 years repairing cars, pickups, and suvs for a living. I am absolutely not a believer in this style of air filter. The vast majority are improperly maintained which has the opposite effect of what the filter is supposedly designed to do (increase power and fuel economy by being more freely flowing). Most of these I’ve come across in the wild are letting dirt into the engine. I just had the plenum off of an engine last week running a k&n. The amount of oily black carbon and dirt collected in that plenum was astounding. Guess what else, low compression on all cylinders. Dirt introduced into an engine tends to have that effect.
Not being facetious, but wouldn’t more dirt carbon buildup inside a cylinder raise compression. Because you’re filling up the volume of space for the same given amount of piston stroke.?
@@DB-qm4jx carbon buildup on the tops of the pistons can raise compression like you mentioned. In the case of poorly filtered air entering an engine, dirt has abrasive effects on cylinder walls and piston rings which impedes their ability to hold compression.
@@ReeveHelalV fair!! Thank you for explaining more thoroughly. You are completely correct and I appreciate the immediate response.
Looks like marvel mystery oil to me
My oiled filter identifies as a dry filter lol
And they clogged the MAF sensors
As a GM tech I have removed plenty of cold air kits and plugged air filters that have caused damage to the cars fuel system. These kits cause more problems than any dreamed up benefit.
You mean poor maintenance and parts that aren't tuned for cause issues? Incredible deduction! Doesn't matter what filter is in there, people are lazy and dumb.
I just found that out in my silverado :)
Make the calculator accept metric.
thank you for the info
but not related to the video, 1 tab of youtube in chrome and my pc is shitting itself. glad to have both youtube being absolute trash and chrome too
why'd i get recommended this right after cleaning mine???!
Always easy .
Clean it with break cleaner
Wd 40 on it and go.
Do this for years and years on my k&n .
Its a replacement filter for the original filter
I love Banks products but hate those filters. Thats the only reason why i dont buy a CAI from them.
im oiled all the way untill it comes to volvos thats a big nono
He must've done some time in Prison. He still uses his Prison pocket.
The aerosol oil spray is better
NEVER use an oiled air filter , on ANY engine with a MAF . The vapor will accumulate and burn on the front of the filament . It can never be cleaned without damaging the coating . I will send only wrong information , and probably a code . But , it is great on my 1965 Pontiac coupe .
As long as the oiled filters are properly maintained, they will work just fine with vehicles that use a MAF. We have thousands of customers that use our oiled filters with no damage to the MAF.
