I’ve run K&N on every vehicle I’ve owned for over 20 years. Without issue. If I known I’m going to be off-roading for a weekend, I clean and oil it before and after. If you live in dust all the time then stay paper. If you highway drive 6 days a week and try to get off-road occasionally got K&N
I have used K&N's in a few vehicles over the years - no problem with them for longevity, and no complaints about performance (hp difference is negligible and over the longer term, they don't not appear to have contributed noticeably to any additional engine wear)
Go with Wix if you care about air filtration. I haven't heard of any brand that beats Wix in that regard, for both intake or cabin filters.
Mahle is decent i believe they are OEM supplier for BMW and alot Europe vehicle as compared to Acdelco for GM and domestic vehicles not talking filters just in general there.
I'd just go with the K&N as you seem to want the best bargain for the $. These K&N filters are very good and will be the last time you buy a air filter. Simply next time you need to replace what I do is spay clean through both side with a garden hose. Air dry, spray a lil oil on it "k&n" re-oil. The oil is what collects the dust. And reinstall back in the car. Plus there proven to add 1 or 2 HP.
I actually use one in my 21 Civic type R, recently cleaned and reinstalled for the 3rd time.
Been using a K&N on my car since 1996 or 1997 when my car had around 90k miles. Car currently has 505k miles. I clean it once a year. It flows like a new paper filter even after 20k miles. I still use a paper filter whenever I have to wait for the K&N filter to air dry after cleaning it.
Get an K&N or HKS air filter and never buy another filter again. They usually come with a cleaning kit which is used once a year. One of the better investments I’ve made for my car.
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 had a Jeep with a K&N air filter with the "do not discard- permanent filter" stickers on the air box. I loaned it to a friend for a few months, and to thank me, she took it in to get the oil changed. They told her the air filter was oily and needed replaced, and she told them OK.
I will never again waste money on a stupid K&N.
