Default Stock stereo & E3 spark plugs?

Can someone tell me what the grey plug is for in the back of the stock stereo? i know the black one is the antenna-

Has anyone used E3 spark plugs on a NA or to be specific, what are some of the better spark plugs recommendations other then the ones listed on the tsrm?

Does the mk3 have pcv valves or are they just hoses that connect to each vavle cover, there seems to be oil seeping around the edges and near the TB.
