I worked with a testing manager for Wix 10 years ago and I asked him about K&N filters. He said that they are okay brand new and their effectiveness drops after trying to clean and re-oil them. And you are assuming that the person using it is actually clean correctly and not over oiling it.
I use to run K&N on a few cars, until I realized how dirty the intake tract was post filter. I still run one on my supercharged car because it fits well and lets be honest looks good, but on my daily and SUV I want to last a long time I stick with paper.
I've got a K&N filter in my '22 Sport 2.0T. No issues at the dealer, never even brought up.
Get one from K&N and wash it every 6 months, lasts for many years
I have and like the K&N filter that drops in the factory housing, i like that you can just clean it and put it back in. You won’t notice any difference power or fuel milage wise.
I had a 2014 Ford fusion with a 2.5l engine and put one in and I could definitely notice a difference. Plus it is a lifetime filter so you'd never have to replace it again. Only clean and refill with oil.
I have the k&n filter and I don’t notice a difference, the only upside would be you can clean it and reuse it but other than that there’s not much of a difference than a paper filter
You could look at a K&N drop in filter. They flow better and can give a little performance boost.
K&N seems to always have the best option.
For my 2018 tuned GT, I just got a K&N high flow drop in air filter to swap into it. You can get it off of American muscle for like $60. I'd say do that and save more money for tune/exhaust.
