The mann is or as someone else said, no real problems using that.
Personally I prefer the mann frecious plus filters due to annoying allergies. Though they are a huge pia to get for whatever reason so I am currently using a cortero filter. Good luck so far
Pros: no real problems
Cons: huge pia to get
Both are good for oil and air filters. But definitely get charcoal. Made a huge difference for a few more dollars on something you don't change often.
Pros: huge difference
Mann is OE manufacture. When I worked at VW/Audi, our parts department would actually sell those Mann as oe. That’s what customers would get during their 20k services.
Pros: OE manufacture
Mileage: 20000 km
Mann filters have always been my go-to for my VWs and they've never let me down.
Pros: never let me down

I put the KN in my 2019 mini cooper s, better performance noticed. Nothing huge though.
Pros: better performance
Cons: small improvement
Vehicle:
MINI
Due to restrictions in SCCA Stock class rules, I only run a K&N panel... though dyno time revealed only marginal hp gains (really, its a poor ROI over the stock paper, but the K&N was part of a diagnostics test my team was doing, so it was free).
Pros: marginal hp gains
Cons: poor ROI
Vehicle:
Volkswagen Golf
I threw one in my Dakota I had before the GTI and I could notice the difference.
Pros: noticed difference
Vehicle:
Dodge Dakota
In my experience they are a waste of money with risk of fouling MAF sensor. I’ve tried them in my diesels and gassers. I never once wasted my time cleaning and re-oiling a K&N. I just threw it out and went back to OEM.
Cons: waste of money, risk of fouling MAF sensor, not worth cleaning/re-oiling
I had a K&N air filter in a NA engine VW. Some particles do get through as I could feel grit on the inside of the intake pipe past the airbox. I washed and oiled the filter per instructions.
Cons: particles get through
