You wont have over oiled air filter if you buy the Pro Dry filter. It doesnt use oil.
When i am evaluating a purchase of any kind i prefer facts to opinions.

Hey Vincenzo,
My humble understanding is that in today's super-computerized engine setups, the performance mods (CAI, exhausts, etc.) won't give you maximal boost until you also re-program the engine. In your case, you may be looking for something like this:

Of course, if you're also planning on doing exhaust and throttle body then you'd want to step up to their Stage 3 software. The Dinan software is safe and will not void your BMW NA warranty. Whereas with other 3rd party software, the dealers may give you a hard time. By the way, my gym trainer (who is a BMW nut) tells me that SuperSprint makes the top exhaust out there. I'm pretty happy with my Dinan exhaust though.
BTW, 30 hp from a CAI?? U sure bout that? Dinan's website says 13 hp increase, and that's WITH the software.
