100% should. When you buy the filter from BMW, it comes with the 2 o-rings and a washer for the drain bolt.
I buy oil from BMW and it is like $4.60 a quartz (give or take a few cents). If you go out to wal-mart and try to buy synthetic oil, price is almost the same so for me I rather get it from the dealer just to make sure since I plan to keep the car way after the free maintenance period.
