Air Filter mod: Recommended for N55?

I haven't looked into an Air Filter mod since my Mustang days since on N/A motors and brands like M-B/BMW I've found that messing with the OEM dynamics on something so miniscule isn't really worth it.

However, this being a Turbo, and knowing some Turbo cars see considerable gains from a simple and healthy Air Filter type of mod (again though, talking about "lower end cars" that I've had experience with in the past on this), is it something worthwhile on a BMW? Or would it be a waste of money, or regressive?

I also wouldn't be opposed to some extra throat to what is IMO an already nicely throaty motor.

Will add noise at expense of fouling your MAF if you use an oiled filter.

Also, there are virtually no performance gains on a FI car unless the stock filter is really restrictive.

Thanks, was hoping that was the case as I don't need to spend the extra money.

I figured it would be a moot mod since on Turbo cars that DO benefit from it, you see tons of threads about "Intake/Air Filter" in their respective Forums. I figured BMW would dial the motor in pretty much as best it should be from stock.
