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.

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.
