K&N Airfilter
Someone out there also considering changing the airfilter to a K&N one?
I've heard about mild improvements to engine characteristics (I'm not talking about adding tons of HP, I know the increase is limited to some HP) and was wondering if former Z4 owners have used them... I suppose the standard airfilter will be of good quality too, so I don't know if it would make any difference at all. What do you think? Cheers, Niels Edit: I can imagine that this post looks like a "I wanna do some cheap tuning"-post, but that's not it. I just wanted to get some discussion going...
