The sensor I bought was the $12 generic one wire from Autozone. It was mounted in the collector of my exhaust. I was very surprised when the gauge started showing it running leaner after just 8 hours and failing with in the next 3. I was told that the heated ones mounted further down the pipe are less likely to suffer from lead poisoning from avgas and would last much longer, but since it was just a experiment to see how they worked I did not want to spend the extra $.
