What are these shields that they cost upwards of $110? Anybody have a pic so
we could see how to make one? Stands to reason that the sensors should be
shielded both from road crud (it turns out that the oxygen sample comes
through the tiny passages in the copper stranded wire, and it wouldn't take
much to clog those up) and from cold air. They are kind of hanging out in
the breeze.

Anyway--a hundred and ten bucks? Would that be the gold or the platinum version?
