i've always heard K&N are overrated and more restrictive than paper filters. yes you have to change paper filters, but in the long run they are a better filter even if the cost is higher. thoughts?

There is quite a bit of chatter on this topic if you search. I use stock BMW filter although I did remove the secondary filter from the air filter box.
Some state they see and hear a difference, I for one can not say I have. I do think i get a bit better gas mileage.
