Denver, Colorado has some of the strictest particulate laws anywhere. If
you can see smoke, it is not going to pass.
Here in Canada if you can't see smoke it ain't running.
And don't even get me started on those bloody VW Jettas - I have to turn
my heater or AC off everytime I get behind one - or choke.
