What Air Filter Should I Use? | Oiled vs Dry Explained

[@jamescampolo7824]

When cleaning a K&N filter, you should flow the air/water from the inside to the outside. By blowing it from the outside in, you are pushing the junk further into the filter material.

[@ChuckG92]

Aaaand the K&N instructions specifically say to NOT use compressed air to dry their filters...

That too made me cringe a little. In addition to rinsing from the outside, basically further embedding the finer debris this filter caught.

[@executiveinvestments]

Aaaand......he only blew off the part where water was pooling with very low psi.

[@executiveinvestments]

@ lol that low pressure water isnt embedding any dirt. Ur delusional.

[@ChuckG92]

@@executiveinvestments Aaaand the instructions say no compressed air.

@@executiveinvestments Oh great, here comes the annoying teenage internet warrior, calling people names and surely has facts to support their argument(s). It's not like the manufacturer of these products have a clue and give solid recommendations on how to service their products that, in good faith of believing, they poured R&D into and made. Surely not.

[@Scott-uj2bi]

I was on board up to the compressed air. That practice will give you more air flow, bigger holes in the air filter. No matter what filter you clean you always push from the inside to the out. Inside engine outside road grime.

[@stewart-D]

Fill a bucket with warm soapy water , put the filter in with the open end up and spin with your hand back and forth for a couple of minutes. Wash with the hose from inside and sit it on the clothesline to dry , done . Tip the water out of the bucket and see what came out.

[@brpjana8080]

Thanks.... I am going to do your method in the future

The instructions say to rinse from the inside out. If you rinse like you did in the video demo here, you risk further embedding the debris that the filter caught. I assume K&N has these specific instructions since rinsing from the inside-out will encourage the debris out with the help of the provided soap.

[@cjponyparts]

With low pressure water there is very little chance of forcing any debris in. I have always cleaned the outside to get some cleaner off and then inside out at the end to remove anything left behind. I was shown this method by a filter company many years ago. By all means clean it any way you feel comfortable.

[@tedjones-ho2zk]

Thinking the same thing, should be washed inside to flush out. Also using compressed air is a no no.

@@tedjones-ho2zk The compressed air thing eludes me as to why that's a no. Is it due to the risk of punching holes in the filter material? If so, perhaps something like an air blade would be better suited for flash drying. I have a C&L intake with a monster sized filter that I oiled. Whenever I clean it, I put the filter on top of a blower box I made with a heater fan blowing through it. That generally gets that thing dry in just 3hrs.

[@executiveinvestments]

@@tedjones-ho2zk this guy did it both ways and did it properly. Low pressure water isnt embedding any dirt. lol

[@Stangdriver2020]

I have utilized both oiled and dry aftermarket filters in several different cars and trucks and oiled is the way to go. I don’t like the aerosol spray oils as I feel it wastes some. MainTENance every 10k.

[@tenentenegrao]

Very timely and unexpectedly interesting. Hope you're doing your Ford Nats cruise this year!

[@cjponyparts]

That's the plan!

[@AtticAZ]

Dry flow; the way to go.

[@lancemillward1912]

Coupd you not use the compressed air to blow out excuses oil?

[@israelr6636]

Awesome information and very useful video. Thank you.

[@vagabond7883]

If your vehicle is still under warranty, ask them if the engine is warranted against damage by using a K&N air filter. I guarantee their answer will be NO.

[@Mr03fatboy]

Not supposed to use compressed air, that could damage the the pleats, also rinse from the inside out

[@chillappreciator885]

Can I skip the oiling part and keep it dry?

[@brunoniccoli1546]

Amazing video! Thank you

[@jamescampolo7824]

I recently changed my air filter on my 2018 Mazda 6 2.5L Skyactive. I was getting 33.7mpg with the K&N and now I am getting 34.7mpg with a Purolator One filter after 1000miles. These mpg ratings are per the car's computer.

[@mrau92me]

Just about every car computer gas mileage estimate I've tested gives an inflated estimate. The average gas mileage is always higher than doing it the tried and true way. To check it the most exact way, zero your trip meter when you fill up, then the next time you fill up (if possible, use the same gas pump or at least gas station), fill the tank letting the auto shut-off do its thing and add no more fuel, then take the number of gallons you added and divide it by the reading on your trip meter. It's also best for consistency to refill at roughly the same level of emptiness per your gas gauge.

[@jamescampolo7824]

I agree, but if the computer has been reading 33 mpg for years and you change the air filter and the mileage goes up one mpg it's the filter. The computer is using the same baseline parameters before and after.

[@wildmanofthewynooch7028]

run the water from the inside our that is the instructions on K&N and Banks oiled filters.

[@glennbeck5138]

Thanks!

[@alexvaldez7317]

Can y’all make a video on how the 2022 gt mustang lost power and on how to take out that air filter out of the new 2022

[@executiveinvestments]

no

[@cyclonekevin6199]

What is the replacement filter, for the Rousch CAI? Part# or measurements. Thanks

[@ami2846]

I have a Nissan Sunny 2015 (Middle East model). The manual says I can use “dry paper” for dusty conditions, and the other option is “viscous paper type”. Is the latter the same as the oiled filter you’re talking about?

[@enginegremlin]

It's always Coke. Never Pepsi

[@vincentbute9170]

Always Coke. Second that😊

[@highplainsdrifter9631]

Coke is it!

[@Rocky-life518]

Hello CJ pony can you please help me I bought JLT air intake for mustang 2015 v6 now I need to replace the filter but I don’t know which size should I buy? Can you please send me with link to your site? Thank you

[@dougwatson6406]

I prefer the dry filter and it can be cleaned with a cleaning kit no need to replace it.

[@SixOneFive]

Airraid synthamax dryer filter is washable and reusable

[@ireneclark745]

[@Warg666]

So for a wet filter, take it out about an hr or so after u get home, and clean it an let it sit out if ya not going any place the next day, and install it then🤔

[@StephenSmith-zu3lk]

Totally wrong and bad information, never use a air line never oil the inside

[@SVTJD]

It’s coke. Every time. Never Pepsi. Not an option, just fact.

[@lobbyrobby]

Coke for taste except they went woke so now it's Pepsi I guess. I don't drink either anymore so the correct answer is oiled filter connected to the supercharger.

[@chrisbusch1970]

you can clean the dry filters in the same way

[@A.C.71]

After talking to the senior K&N tech yesterday I can tell you this video is really bad advice in multiple areas.

[@Diesel-rocket]

Why so buddy

[@toyotabrony]

Doesn’t look like a bad advice to me, as it seems to be straight forward informative.

[@mkviis]

Not necessarily, my dry air filter is reusable i.e permanent

[@vG_Mikes_Amazin]

Coke is ALWAYS better than Pepsi sir.

[@Javierm0n0]

Incorrect, Pepsi is better tasting. Coke is better for light rust removal and cleaning chrome pieces🤪

[@devionwatkins5638]

Root beer

[@vG_Mikes_Amazin]

@@Javierm0n0 Coke is for the men Puts hair on your chest 😎😏😄😂😂😂😂😂

How Not to clean any air filter.

[@toyotabrony]

Wrong. If u want it to last, u gotta maintain it. Always how to clean it.

[@kjstars]

A filter is a filter.

[@toyotabrony]

But there’s better benefits than just filter.

[@nickjames5885]

Wash it from the inside out not everybody is perfect

[@lassassin2239]

😂😂😂 Absolutely.A horrible video too.Have an air compressor and absolutely destroy your air filter

[@tahustvedt]

Another K&N video tells you to be very liberal and shows you to absolutely drench the filter in oil: pohkTM6jaDs
