Review on 🔌 Delphi ES20317 Black Oxygen Sensor by Paul Lee

This oxygen sensor is about half the price if you bought it from an auto parts store and installed it yourself. If you were going to a mechanic you would probably be looking for $100 for a sensor. I bought both (my truck has two in the front and two in the back) for $35 each and installed them in about half an hour. Quite easy. Another plus, which is less of a product and more of a design advantage, is that the front and rear sensors have different connectors, so they can't be confused. Of course, you should be aware that there is a catalytic converter in the front, but it's always nice to see how intelligently designed old cars are (I have a '96 Chevy). And there's plenty of hands-free room where you don't need that special socket that's only used to replace oxygen sensors. I just used a wrench. And Delphi is one of the best. Made in the USA.
