1)NGK BKR6EIX or Denso IK20 or VK20Y
2)Get one from dealers or Castrol, fully synthetic VW spec 504 000/507 000. 5W30, 0W30 for fuel economy, I guess it is getting quite hot in SA so 5W40 or 10W40 might be better there or 10W60 if You push it hard quite often.
3)no replacement interval specified, basically replaced when it gets clogged and interferes with fuel flow which should never happen if fuel is clean. I replace them with first service after buying car as a preventative measure and then every second year if I own car that long.
4) as Singh says
