Review on 🚀 Enhanced Denso 234-9126 Air Fuel Sensor for Improved Performance by Peter Tennant

I replaced my sensor myself after the store asked $100 to tell me why it wasn't smog. After asking which tests are not running I figured it was being delayed by the sensor. In fact, after replacing it with this one, the car went through smoke. I also noticed that the car has better gas mileage and runs smoother. The socket that Amazon says is "often bought together" is the wrong size to remove/replace. Double check before ordering. It's very easy to replace it yourself (almost like changing a lightbulb).
