Sports air filter

Which Z4?

Not that it matters…a good stock filter from Mahle, Fram etc is your best choice :thumbsup:
 
Good old fashioned panel filter from K&N - lasts years and just needs a clean when you do your service.

I took a K&N out of my car as I am not sure about the correct way to clean it. Is it that much better than a conventional filter?
 
This one should be good given the price:

I took the K&N out of my car. Who wants to clean filters? Didn't notice any performance reduction. To be honest, I would see more performance if I just lost 5 pounds off my belly!

Glad I'm not alone on that one 😁
