I am replacing what's almost surely a failing O2 sensor in my inline VW
motored van and I wanted to see what the List take is on O2 sensors.
There is a pretty wild difference in cost.   But they seem to be simple
things and every car has a few now a days, not many of them seem to fail
too often...
  Is it worthwhile spending nearly a hundred bucks for a Bosch to put into
my van, or can I use a generic autoparts store brand and expect to get a
few years of service from that and much less cost?

  What say ye? and thanks
