Matt that's the smog pump (auxiliary air pump) fitted only for the US market. It's not required here or needed so you can disconnect the two core cable plug, the hose to the housing on the head and the housing and bin them. You will need a blanking plate to seal the port on the cylinder head and I can supply said blanking plate if you would like one.
I removed the one on my 2000 Z3 and it makes NO difference to the emissions whatsoever.
