K&N air filter after 2.5 years pic.

I clean both AFE and AEM dry flow filters every 30K. The AEM on the Pilot seems a bit more dirty that the AFE on the Tacoma. Both see similar driving conditions.

Use stock filter and change at regular-normal intervals. That clogged filter has hurt your efficiency and performance for a while. That’s not money well spent…

I am shocked any BITOGers are using K&N.

Not much in the way of dirty air here in South Florida. The K+N works just fine. Have one on my airplane too.

Yeah, it's just now starting to filter well

in some aspect you are correct. I've noticed that with HVAC filters at home. for that type of filter he had, I probably would just tap it a few times and let the big stuff fall off and throw it back in. I'd kind of like to see or perform a test to see how cold the cleaning agent and the oil will get before they turn into solid. it's kind of a nuisance to clean and with dry flow filters now readily available on the market it just makes no sense that they are still making cotton guys and oil. if it had worked out so well I think they would have implement it in people's homes.

This filter was installed in my Chevy Trax in March 2021. Caked on dirt on filter and pre filter side of intake tubing. However, the post filter side of filter and intake tubing was spotless. Clean as a whistle. Replaced today with paper filter.

Complete junk toss that right in the trash and install an oem equivalent paper filter.

Depends where you live. Out in the southwest, sure. PNW, K&n is excellent

And yet, the K+N seems to be the right choice for certain conditions. It is particularly good for aircraft use. As water will not affect it.

Always been my experience. Have one in 5/6 of my vehicles and have for years.

I have sent in my last two oil changes to be tested. Will post a new thread with results.

You'll see no difference vs. running a paper air filter.

Or just clean and re-oil this one...

Every young guy deserves these just once:
- K&N air filters
- Flowmaster mufflers
- Register with wrong party

That’s not bad, my non-mechanically inclined brother’s went 113k without a cleaning because he’s not very bright.

K&N with 113,XXX miles

Changed out this K&N filter on my brothers 2016 Ram 1500 Hemi. Doubt it was ever cleaned properly, when asked how it was cleaned the reply was I blew it out with the air compressor. All I could do was laugh, I said just change it as you've probably compromised the filter media by blowing it out...
