What is this....and this?

[macdrekc]

Two questions...I have a broken hose (A) coming off of my intake tube. just wondering if anyone knows the name or part number for it so I can get a new one. The other (B), I know even less about. The hole is threaded but I cannot figure out what goes there if anything. I have had a problem with my X bogging when accelerating below 2500 rpm, and revving from idle, could either of these be the cause? My SES came on as well. Is there a way to pull the error w/o an obd scanner? Sorry for so many questions, but BMW has until recently been out of my price range. BTW my X is a 03 4.6
