K&N high flow engine filter

I ended up taking the k&n filter out and threw it away and got an oem filter. I cleaned what I could in the intake tube. But I ended up trading it in shortly after that anyways. Now don’t get me wrong, the engine still ran fine. But the question is, for how long. I just checked my intake on my new civic the other day. I bought it brand new with 20 miles on it. It now has 25,000 on it. I have a tendency of overdoing things so I change my filter every 10,000 miles even though I really don’t need to but oh well lol. But after 20,000 miles that intake is still spotlessly clean like brand new!

I get it. Thanks for your information

You can clean it. You just have to disassemble each section back to the intake to get it all.

But do you really want this fine dust building up in your intercooler and going through your turbo? I would rather not risk it and stick to the Honda filter. There is no dust getting passed that filter for sure. But like I always say, it’s my opinion and everybody has their own.

I appreciate that. I might consider it before putting the k&n filter. I'd like to see how would the engine react with that filter for a few months

One other thing that's been covered in other threads is the MAF getting coated with oil residue when too much oil is applied to the filter. In the past; I could never be sure if I applied too little or too much oil for the thing. But back then, Honda's didn't have MAFs. That, and the other reasons listed already, have motivated me to stay with OEM.

I've been happy with the AEM dry filter, less restrictive than oem, but no oil to fool with. And so far, my intake looks pretty clean.

I just installed an AEM dry filter in my coupe. Similar to K&N but no oil. Simply wash when necessary and reinstall. So far, so good.

Factory filter every 10k miles. Living in AZ, that's about when it looks gross. I also replace the cabin filter every 5-10k depending on smell and how dirty it is. These things are cheap af so why wouldn't you do it?

I went with the aem dry flow drop in filter only had it a few days so can't say much about any improvements.

I change my cabin filter and air engine filter once a year and oem cabin and engine filter are cheap(18$) and plug and play hassle free.

When it was time to replace the engine filter I replaced it with the K&N one. Ive had no issues and no it wont void your warranty. However, don't pop it in based solely off the hype that you'll suddenly get amazing gas mileage and a noticeable difference in horsepower because you won't. I noticed no discernable difference between the stock filter and the K&N. If, however, you are opting to put it in because in the long run it will end up saving money since you can simply clean it and reuse it, super, it will more than live up to your expectations. But like I said, don't go into it thinking you will notice any difference.

the math doesn't add up unless you keep the car for like 15-20 years or drive like 30k miles a year. I was doing the math, the K&N filter costs like $50 and a standard filter is like $15-16 that means you get 3 filter replacements or 4 once you factor in needing to buy the K&N filter clean and oil kit and thats like a 100k miles worth of filters depending on how often you change them, I drive like 8K miles a year it would take me a decade to reach price parity and I've never owned any car for that long. Maybe if you plan to own the car till the wheels literally fall off then maybe but even then I would pay for the convenience factor of a 5 minutes filter swap over cleaning, drying, oiling, touching up the oiling and then finally reinstalling the filter that you get with a K&N and i'm speaking from experience, many of my cars have ended up with K&N filters at some point along the way from Ram Air and Cold Air intake upgrades and 1 or 2 straight filter swaps.
