My car is up for inspection. I fell for this useless piece of tin many years ago and bought one.
I still have it.
If the inspection station will let me have a free emissions test for science sake, I can do an A - B test of the thing.
I almost threw it away a couple of days ago. I took it off the car ages ago and found that it did so little that i hadn't realized it was even there.
I completely forgot that I had the thing installed.
