There shouldn't be any issues running oil based filters. Most people who have problems apply too much oil to the filter thus coating their MAF sensor with oil. I've run oil-based filters on all my NA and forced induction cars with no problems. If there was indeed an issue, a multi-million dollar company like K&N wouldn't be in business anymore. Just my 2 cents.

My Ride: I have an 05 545i. It's a manual with a few options. This is my first BMW but I don't know how I'll ever be able to switch to something else.
@Michelle:
Can you post up any of these dyno sheets? I'd love to see some hard evidence to support that. I know BMC is used for F1, but it's going to take more than that to make me a believer.

It's not that significant of a difference, as you stated, 1-2 for some, 2-4 for others at most...save the $50 if you like, we trust BMC and use them with the scoops.
The problem with oil filters, from my understanding is that people add oil uneccisarily ...

Don't they come pre-oiled? Why would anyone add oil to a new filter? I have had K&N in my cars since they came out and only cleaned and added oil to one once. If someone screws up their own filter, their problem. These things are not high maintenance

+1. Hopefully I'm not speaking out of turn here but I had a customer asking if they should go to BMC if they have K&N. I told them not to bother.
If you are running an OEM filter and want to decide K&N or BMC, then that's a whole different story (you can't go wrong with either IMHO).

they don't look oiled and maybe that's why people add oil
