My car has 71k and the last time the spark plugs were changed around 45k.
What kind of spark plugs do you recommend? Do I have to stick with BMW parts? What about the coils? Can I just get an off brand from the local auto parts store?
Thanks!

I would change the spark plugs first, it sounds like you need it anyway.
There is any easy way to see if it is the spark plugs versus the coils, you simply move the coils and see if the problem moves with the coils.
That being said, I will bet that it is the plugs and if you have not had your intakes cleaned that it is carbon buildup.
Also, just get the plugs and coils OEM, don't scrimp on these...
