My experience with K&N filters is not near as good as the comments on this video. I ised one on a gas pickup and found it collapsed, not dirty, just flimsey and sucked in to where the filter was not where it was supposed to be so the dirty air had direct access to the engine. A friend of mine that runs a cummins on dusty NE roads completely dusted his engine using a k&n, every cylinder had blowby by the time he knew there was a problem. You said "i can darn near see through this filter so it must flow better"...youre right, it does flow better, because it doesnt filter. YMMV. I think a highway truck would maybe be ok, but i would NEVER use a k&n on a diesel in dusty conditions. I have a 18' dmax and use only hastings or oem paper filters. Best luck, i love your videos.
I do a similar thing with mine. I have one K&N and a paper filter. I use the paper for a day or two after oiling the K&N to let that oil soak in really well. Works like a charm. Good luck.
Good video bud. Iv been running’s K&N for bout 150k miles now in my Dmax and love it but as often as we gave to service man it’s an ordeal to clean dry oil then dry….. it’s usually a few hours process to do it right. Mr TN is a freaking genius….. hadn’t even thought about buying a 2nd one to have ready on hand. The day after he posted that video I went and got another one. You boys be safe I’m heading back to Indy in the morning
I did, made a lot of sense when i thought about it. Caught me off guard when you commented on this video. It wasn't supposed to be public yet, lol. It may dissappear then get put back out later
@@CFarmer lol, I was wondering why it didn’t pop up as a new video when I saw it! Somehow it popped up when I was watching another video, I agree it was strange
Man I just bought the motor craft stock replacement for my f450. $100 from dealership $75 on Amazon. K&N is only $100 on Amazon. Def going k&n on next filter change
Great video! You are spot on with oil getting on the MAF. You can't just clean, re-oil, and throw that thing back in there! Here's my .02 on K&N (not that anyone is asking)....they are great performance filters for airflow, but as John commented, I don't think they are that effective at engine protection. I've always told folks they are good for keeping rocks and small children out of your engine. LOL. Another way to look at having to constantly purchase "throw-away" filters like AC Delco or WIX....that's just another business expense you can write-off come tax time. I wish AMSOIL still made their dry, reusable filters.
Thank you! I've never tried the amsoil. that's a good point. I can see where they wouldn't filter as good as the AC Delco because there's just not as much filter there.
Thats the right call Dont oil it … we drive a lot difetent environments conditions keep it dry so tou wont get the oiled dirt colected in there So just wash it frequently Cummins has the air box down pipe on the oil filter access for a reazon I guess You have to remove the top of the box lid to get the down pipe out of your way to change the filters .. ( the right way ) So thats your chance to take a look to the air filter right there 💪
@@CFarmer Supposedly they filter better as they become dirtier. Just not sure I trust them. I've used them on quads and have found dirt in the air box beyond the filter. Good luck. I enjoy your videos. Thanks.
@@CFarmer I noticed when you removed the throwaway filter it had what appeared to be household central air filter in front of the paper throwaway. Why couldn’t you do the same with the K&N? I hope this isn’t a stupid question as I’m not familiar with Diesel engines but gunna have to learn
I tried one on my 2020 and it gave me a check engine air filter message that won’t go away now. Dealership said to go back to a paper filter or the engine will go into derate. Have you heard of this?
Not a good filter if your in dirt and a lot of dust. If your in Town or just stay on the highway it’s a good filter but not if you go off road or in dusty environments. It’s not good for your turbo.
You did the rigth thing to use a k&n filter . I do recomand i have on all my cars and i see the difference and my engine drives smoth and last very long also is good so save the planet
Really bad idea, K&N is a performance company. Allows too many particulates into the combustion chamber. We drive through construction zones while they saw cut concrete, we drive through dust storms and even the occasional dirt road behind other cars. Want to insure you won't get 500K out of a motor? That's one of the ways.

That's what i was thinking, thank you!
I see you saw Mr. Tennessee’s video, I did too! That’s a really good idea! As always, God Bless and safe travels!
I did, made a lot of sense when i thought about it. Caught me off guard when you commented on this video. It wasn't supposed to be public yet, lol. It may dissappear then get put back out later

All good, lol
Great idea! We’re all about saving money any way we can 👍🏻
O yea
Man I just bought the motor craft stock replacement for my f450. $100 from dealership $75 on Amazon. K&N is only $100 on Amazon. Def going k&n on next filter change
Dang, i thought mine was expensive
I run one in my Ford, they work great.
I think I'm gonna like it

Great idea, but having a hard time finding one for mine. They are shaped differently had to take one back and couldn’t get another one yet

Good points, thank you for your comment
I'm not sure but I don't think the k&n will filter the fine dust out like the factory one does.
Your probably right. Just looking at the 2 filters the factory is definitely going to filter better
@@CFarmer Supposedly they filter better as they become dirtier. Just not sure I trust them. I've used them on quads and have found dirt in the air box beyond the filter. Good luck. I enjoy your videos. Thanks.
I'm going to keep an eye on it and see how it does. That's one reason i didn't buy 2 off the bat. Thank you.

Lol, I'm looking online to see if i can find a screen or washable sock now. Good question
I went with the Banks Ram air with reusable filter
I'm holding out on intake. Think I'm going to use the factory box with wherli pipes. Did you get any whistle when you swapped?
@@CFarmerI did not get a whistle but did notice a more throatier sound
Good video let me know how you like it. I know with mine I can hear the turbo a little bit more and the Jake brake. But I change the whole thing out
Yea, i didn't get any noise but i can tell its breathing better
I tried one on my 2020 and it gave me a check engine air filter message that won’t go away now. Dealership said to go back to a paper filter or the engine will go into derate. Have you heard of this?
I have heard of it but not ran into it myself
Great video! Thanks.
Thank you!
Not a good filter if your in dirt and a lot of dust. If your in Town or just stay on the highway it’s a good filter but not if you go off road or in dusty environments. It’s not good for your turbo.
I figure with 95% of my driving being on the interstate i should be ok
Watch project farm on TH-cam on testing air filters.
I'll check it out
@@CFarmerdon’t waste your time as the test is inaccurate due to the K&N being an active filter.
How are you finding the filter so far?
You did the rigth thing to use a k&n filter . I do recomand i have on all my cars and i see the difference and my engine drives smoth and last very long also is good so save the planet
It's been a while since i made this video. So far I'm really liking them
