Cheap Easy Way To Clean and Oil a K&N Air Filter without a Recharge Kit using Household Products

It's super easy to clean and re-oil your K&N Air Filter with products you've probably got at home - some Fairy Liquid and some light spray oil.
In this video I show you how.
Edit: I've had some messages saying I've got a total disregard for the safety of people's engines, as mentioned in this video, I've been doing this for years with no issues. If you're worried about it, don't do it!
The official kit is a degreaser and a light spray oil, same as this method, I just don't want to buy something for £15 that I already have for 15p.
I also did some digging, and found that a oil analyst did some testing on K&N air filter oil and it's almost the same as ATF.
PS. F1 cars used to run no air filters and just a metal gauze to keep the stones out!
Or just buy the proper kit...

Thanks for the advice, i cleaned it in a bucket with hot water and soap. After i puted motoroil on it with my finger all around and it worked fine

Yeah as long as the oil is thin enough then it should be all good. 👊

[@dannyingamells6642]

Thanks for a hundred years! The K&N stuff is pricy here in SoCal and things are just too much money nowadays. I used the .99 cent store degreaser called "Awesome!" and some running warm water in the sink and after five applications was able to clear the filth out of the 1.5 year old filter. Then i followed up with some granola aerosol spray (the k&n stuff was actually mineral oil with a red dye). Both cleaners cost me a whopping $2.50 cents USD and was way, way, way cheaper than a new k&n and the costly cleaning kit. Kudos, and cheers!

[@RickTheSpud]

YEEES! Thanks Danny! Success! Glad to hear it mate! 👊😎

[@romeomaindan9982]

Old school oil spray for air filter use regular vegetable oil and engine oil. The new air filter oil sold today has some additives to function better than the old practice. It needs to be dried before use and it becomes thick and almost dry to touch.

[@nunika1975]

DAWN is a a great oil remover. LHM Hydraulic oil is a light mineral similar consistency as K&N. The red colour will help identify where the spray is. Some people also use ATF. Don't use vegerable oils (they go rancid, unlike light mineral oil).

[@RickTheSpud]

The milky brew was the best part. Milky it was! Using edible oil on your auto filter which would then be used to cook sausages is a new part to auto maintenance for me.

[@DefinitelyNotAGuru]

I've never actually used a K&N but am thinking about it for my 420i, do you actually get any MPG improvement with them or is it just a fraction more power?

[@RickTheSpud]

Yeah prob a bit of everything, bit more efficiency all round so better throttle response, slightly more mpg and power, and a bit more intake noise! 🤗

[@golf398]

Would recommend their cold air intake if they have one that is legal for your car in your jurisdiction. Slight power improvement (5hp at best) low maintenance, and most importantly it removes all of the noise dampening your intake has which sounds really good without annoying everyone in a 5 mile radius (if that’s your style).

[@saltygorilla9285]

Nice video 👍 gonna have to try the milky brew also lol. Do you think it would hurt anything if I just rinse my filter with water, let dry and reinstall?

Haha, I know right. Milky brew but not weak, normal strength just extra milk, some people do normal milk and hook the tea bag straight out then it doesn't taste of tea or milk!

[@JohnDoe-wb9ht]

I used laundry liquid in warm water then kept rinsing until no more dirt appeared..cleaned great, let it dry overnight..held filter up to light and no contaminants blocking air holes..I use a light coat of wd40..never had problems in 10 years of doing this..filter increased mpg and throttle response compared to standard filter...a lot of people complain about not using any oil apart from k&n "special" oil..maybe if there's a short distance between filter and throttle body you may clog up your sensor but if like me you've got a long air duct away from engine heat ( behind headlights or fog lights) then any excess oil will just smear onto the ducting.

[@RickTheSpud]

Exactly my thoughts. Careful tho, if you say you don't use the proper K&N branded cleaning fluids on here you'll be in danger of an engine rebuild! 😜

[@JohnDoe-wb9ht]

@@RickTheSpud they'll be the same people that enjoy looking at their special filter in the hot engine bay sucking up hot air, even the pros do this. The amount of people that complain non standard filters don't do what's promised..I say forget about buying one specifically for your car...fit air ducting to throttle body and pass down engine as low as possible (without sucking up small animals or puddles of course)to suck in cold air and buy a large as possible universal filter to fit on..cold air is what will give you the throttle response and better mpg...and ducting doesn't have to be straight or smooth...mines a bendy corrugated type ducting...again..its the cold air that's key. Vrooom vrooom.

[@RickTheSpud]

@@JohnDoe-wb9ht Yep, all of that. Altho I can't be bothered with most of that and just change to a more free flowing panel filter. Just bought one for my MX5 from JR Performance, £12, looks exactly the same as a K&N. 😉

[@Twelve_Gauge369]

Could you oli the filter with PB blaster or WD 40

[@RickTheSpud]

Not sure what PB blaster is, but WD40 dries out and leaves no stickyness to catch the dust. Ultimately in a low dust country it doesn't really need oiling IMO. If I was driving across the desert I prob would. 😉

[@endopaxd.5195]

More effective than using K&N Air Filter Cleaner or Simple Green or other spray cleaners is soaking the filter in a plastic tub or a sink filled with Dawn and hot water. The Dawn solution will reach into every nook and crevice of the filter and remove particulate matter and grease. Spray cleaners will never match this. I do think the K&N Refresher, which can be purchased separately and sprayed on both sides of the filter, is still the best way to enhance the electrostatic properties of the washed filter.

[@RickTheSpud]

Cheers. Will investigate the Refresher. 👊 Hit that subscribe for me... 😉

[@ndiggadee2663]

Good skills I used APC and a jet wash Today just need to oil it

[@RickTheSpud]

Cheers mate, yep, that'll do it as long as APC shifts oil/grease? Don't over oil it, otherwise your car will struggle to 'breathe'.

[@syedarif729]

Can you tell me please can i use engine oil as lube?

[@RickTheSpud]

I guess so. If you can get a thin enough coating on there, and let it drain and pat off the excess as per the video... 👊

[@Qui-9]

If I may make a suggestion, maybe mix some mineral oil with that vegetable oil, or mineral oil with coupling grease or high-tack grease. Vegetable oil alone will oxidize and become gummy, then cured on, and will be a nightmare to remove if at all with oven cleaner. But mixed down, will be easier to manage for next cleaning. The light oil with some tack means it's strong enough to cling but soft enough to catch light particles. Too much tack, and dust will stick to the surface and stay there, rendering the oil ineffective, the oil won't wick around and accept more particles. Cheers 🍻

[@RickTheSpud]

Excellent suggestion. Thank you. 👊

[@Threedog1963]

Work for the cabin air filter as well? I mean, besides the oil.

[@RickTheSpud]

Yeah, guess so! Whatever you spray on it will smell into the cabin so be aware!

[@Qui-9]

Mix a lot of solvent with the oil for this. Straight oil blocks the pores on a filter in a system not strong enough to pull air through a soaked filter. By using solvent, the filter can be wet, then it will dry, leaving just enough oil to coat the fibres without blocking the flow. I suggest 10:1 solvent:oil.

[@samyazad1876]

How about using WD40 instead of sunflower oil?

[@RickTheSpud]

WD40? Could do, but WD40 dries out, oil stays tacky to catch the little particles... 🤗

[@Jonjs99]

Nice!

[@gprakashps3]

Can you please suggest an oil other than sunflower oil? Can I use wd40 or normal engine oil?

[@RickTheSpud]

Have a flick through the comments on here, other people have suggested other stuff that is 'safer' long term for the filter. Unless I was doing the video I'd prob have just left it dry as the UK is not very dusty. In a hot dry dusty country then I'd oil it. WD40 drys out so I wouldn't use that... 👊

[@gprakashps3]

Thanks for the reply. I'm riding a motorcycle in India... It's as hot and dusty as it can be...

[@RickTheSpud]

Oh wow! Err, any sort of oil but make sure it drains otherwise the air won't get through, or the oil will go into the intake which won't hurt the engine but might get all over sensors and senders etc...

[@gprakashps3]

Alright thanks

[@spookyduzit]

I once used baby oil on the filter. And had to decarbonize a day later and Change the spark plugs

[@RickTheSpud]

[@RickTheSpud]

[@RobertBeck-pp2ru]

This is NOT that big of an issue. You can clean the filter with dish soap and warm water. Rinse from the back side and soak again a few more times until the rinse water runs clean. Air dry at LOW gentle compressor pressure (5-10 PSI ), then oil with ATF on the front side ( intake ) of the filter. Let excess drip for a few minutes, then reinstall. No need to purchase "special" oil from K&N. Contrary to many commenters here, you will not ruin your engine with this method. And as a side fact, water injection has been used in engines since WW2, often mixed with methyl alcohol, to eliminate engine knock at high power levels. No adverse effects, and a cleaner carbon free engine.

[@RickTheSpud]

Thanks buddy! Too many armchair experts on here crying about what they think might happen on their fragile precious engines. Prob same people doing launch controls from cold!

I would not recommend using sunflower oil on your airfilter, for the same reason you don’t use it for engine, gearbox, diff, bikechain, paint, teakwood, etcetera: it isn’t the right kind of oil for the purpose. You’ll ruine the filter ánd parts in the intake behind the filter.

[@RickTheSpud]

You don't have to recommend it mate, it's only a tiny tiny amount and I've been doing it for 10 years with no problems. By all means use something else. Spray grease is a bit thick. 😉 I think ATF has a nice red colour if you want to be more on brand!

[@ac7030]

If you add steps for using compressed air to blow out the debris and a hair dryer to minimize the drying time, then you have covered all the things not to do when cleaning your k&n. Also just because you were able to start your car that doesn't proove anything.

Any high flash point solvent (eg. Petrol, paraffin.. ) would work here given that oil residue they'd leave wouldn't be a problem. Normally brake cleaner is best for everything as no residue and if you can find £1 aerosol cans of it. Any oil wg. Engine oil fine.b

Sure, your way does save a few dollars but I believe for a few dollars more it is well worth keeping your engine safe. Just knowing you are using specifically made products is 100 percent safer.

Many things bad about this video. The water pressure is too high. Will damage the cotton. Dishwasher is a good degreaser, works fine. Not sure a about your cooking oil man

[@RickTheSpud]

Thanks for your concern. Water pressure is only out the tap. Could just chuck it in the dishwasher I guess. Oil is oil.

[@troywhite602]

Really you shouldn't oil it period Specially if you have a mass air flow sensor the oil can cause it to clog up anyway you do not need those kits to clean those filters I've been buying those filters for like 15 16 years and never even knew those kits existed because no one used them you don't need them.use Dawn water, soak for 15 minutes let it dry those cats are just another useless thing that you don't need just like gas treatments people forget that gasoline is a hell of a cleaner by itself

[@RickTheSpud]

Yep agreed. Although I'm sure K&N wouldn't agree, that's why they sell those kits! 😜👌

I was kinda interested in this until he used a hose end and more or less pressure washed both sides... DO NOT do what this guy says.

[@RickTheSpud]

Why? It's only the fan jet on a garden hose. Definitely not a pressure washer. Very low pressure.

What the hell is this... Please if your car is worth more that £5 (which this isn't!) please do not follow this advise... You are just asking for problems you should only wash your K&N from one side for a start (opposite to the airflow) to wash the dirt out of the filter instead of pushing into the filter. A K&N filter cleaner kit is around £10 to £15 quid and depending on mileage will last years... It's a lot cheaper than an engine rebuild for getting god knows what oils in your engine. If you can afford the filter, you can afford the cleaning kit. Paul walker would be looking down in shame and turning in his grave.

[@RickTheSpud]

Wow! Say what you really think! 😂 As said in the other comments, if you don't want to do this, then please don't. First off, if you watch the video, you will notice I did wash the dirt back out the way it came in. And commented on the fact. I've also been doing it for years, in all my cars, and it's fine. We used to run no filter or a pair of stockings and it was fine. So this is tried and tested. What exactly do you think is going to happen to your engine by doing this that is so different from using the official cleaning kit? And what I use here is a degreaser and a spray oil. What do you think is in the kit? 🤷‍♂️ I'm assuming you only use manufacturer branded screen wash, just in case?

@@RickTheSpud so is it ok for me to put cooking oil in my gearbox or use it as hydraulic oil? What about in some bearings or even machinery. Or putting in 5w40 instead of 10w40 in an engine. The list goes on, different oils have different properties. And as for the stockings well that says it all. I am fully up for saving money and cutting costs but some people watching this might take it seriously and not as a joke.

[@RickTheSpud]

@@t3hPidGe1 100% there are certain oils for certain tasks, and I definitely wouldn't run cooking oil in a gearbox, although that would be better than no oil, and running 10w40 instead of 5w40 won't hurt anything, but not the best. I upped my oil from 5w30 to 5w40 FS to stop it using any, 5 years ago. No issues. It originally ran on 10w40 semi. Most engines use oil nowadays anyway. From new. The oil on the filter is just so tiny particles stick to it so it doesn't matter what you use. As said in the video, if you didn't oil it at all, any particles small enough to fit through the microscopic holes won't hurt an engine. But as I said. If you don't want to, guess what, don't. I've only done it for 20 years with no issues so I might just carry on. But then my cars not even worth a fiver so... 😉

@@t3hPidGe1 well let’s face it, your response just goes to show you tried to come up with a reason to knock this, but are completely unable to. Starting with changing from 10w40 to 5w40. Go ahead. Perfectly fine. In fact, recommended by manufacturers for engines in severe service cold climates. Lower viscosity when cold is a good thing. On to the gearbox/hydraulic comment. Well that would be silly. Now you’re talking about oils that have detergents and additives, temperature ratings, viscosities etc. just a silly comparison really. The filter oil K&N uses serves literally no purpose as an oil as you know it. It is there to attract finer particles and that is it. It does not need any typical properties that oil in wear and lubrication applications needs. If ricks particular brand doesn’t sit well with you, pick another. I have heard that whilst the filter is out to be cleaned, if you see some pesky wasps or flies stuck in the filter, you should put 1 tablespoon of jam in the bottom of the air box. They’ll eat the jam and not get stuck in the filter! If you use marmite, you’ll reduce the number of wasps or flies by 50% because they either love it or hate it. 👌

[@t3hPidGe1]

This is bad advice. It's literally £10 for a cleaning kit. Would you give this advice to someone with an M3 or an Evo 8 for example. No. For such little cost it's just not worth the risk, of the potential damage it could cause. oils are not the same. Hence why there are 1000s of different oils for 1000s of different applications. People could be watching this video for advice and you could potentially write off someone's pride and joy. That's wrong.

[@jammerlr7780]

Bad advice here. Do this if you want to damage your filter and let you engine suffer the consequences

[@RickTheSpud]

How's that? Based on what experience? I've been doing this 20 years...

[@jammerlr7780]

@@RickTheSpud You have been doing it wrong for 20 years then. Submerging the entire filter permits the dirt and filter to migrate to the engine side of the filter. Applying detergent to the environment side and then flushing from from the engine side to the environment prevents that. Slapping the filter around doesnt help anything other than to damage the gauze element. Alternative cleaner and oils can be reasonably used as long as the proper cleaning and oiling procedures are used.

[@RickTheSpud]

I think you've thought too much about this. You're prob technically correct, but this works too. If it works it's not wrong.

[@jammerlr7780]

@@RickTheSpud It may technically “Work” in some areas and environments, but in dry areas with a lot of particulate matter in the air, its asking for trouble. I was a dealership tech for 15 years in the Southwest of the US and saw first hand the effects many times. Alternative cleaning detergents and oil are absolutely viable and I have used them many times myself, but the proper cleaning method really is important. There are lots of videos and articles online on the subject, but none are better than those on the K&N web site. They have been making serviceable gauze air filters for nearly 60 years now. They likely know a thing or two about how to service their products.

I'm doing it for my environment, the UK. Unless you've got fine sand or dust visibly in the air, I wouldn't even oil it. 👊
