Best air filter?

Yes, but you said

So what if OEM is Mahle? This is the problem with this filter thread in general (but not neccesarily you). People are quick to say "just buy OEM", but OEM's don't make filters - Air, cabin air, or oil. So before you buy an OEM filter you sort of need to know who made it.

My BMW air filter is made by Mahle and aftermarket Mahle filter is some if the best workmanship I have seen when it comes to filters.

Also - I won't say this was "poor" but it certainly was odd.

Never seen construction like this - not sure what you call this levered over tab crimp on construction for the base plate. Not that it matters, just have never seen this before.

This is a cross for the ubiquitous 7317 size Nissan / Honda filter, FYI.

Idk what is going on there, but I get Mahle as it is only filter available for Euro air box on N52 engines and they are of impeccable quality.

Some people here said it was a likely a issue with the foam material chemistry - I forget their exact term. I had used many of these filters prior there Nissan OEM. The air was made in Mexico and the oil filter made in China.

What is the COO of the air filters you get. I agree this is very un-German like.

I have switched to Denso.

So I'm about to change my air filter on my 2019 Fiat 124 Spider, and was looking at a K&N performance filter. But i've seen lots of different opinions on what to use. Some say only use OEM filters, since mopar is saying that their filter is made specifically for this car, others are saying some aftermarket performance filters are better. What I've seen with some performance filters is that because more air can be let in through the filter, more crap can be sucked in and damage the engine. But also having an performance filter will not only increase oxygen and have better combustion, it'll increase a little bit of power. I was looking at K&N filters, but there's some mixed reviews apparently. What kind of filter is best for turbo engines, if that matters. I've seen BMC, K&N and another brand I don't remember. Is performance filters good for just street driving? Or mostly for racing. I don't race my car, but if it helps smooth out power and whatnot, I'll get it, but if OEM paper filters mean better filteration, then I'll get that. I've seen different answers so I want to know what yalls opinions are.

K & N, while they flow well, they filter like crap. The oiled cloth is a nice idea but functionality is awful.
