Review Summary
The oxygen sensor is generally a reliable and high-quality product that effectively resolves engine light issues. Many customers reported it was a perfect fit for their vehicles and improved performance, including better gas mileage and smoother idling. However, a few customers had negative experiences, with some sensors failing shortly after installation or not being an exact fit.

    It hasn't been a year so I dont know if its worth it with the 1 year warranty but as for now it hasn't threw a code for bank1 sensor1 with the voltage reading from 0.635v-0.680v. (It does do its job) I will 100% recommend this to anybody who truly dont want their cars engine to blow up.

    The product is incorrectly labeled on the Auto-Zone website. It is not an oxygen sensor but an air/fuel ratio sensor. The Denso carton the product arrived in also labels it as an air/fuel ratio sensor. Fortunately, the text that describes the product on the Auto-Zone website describes the product correctly as an air/fuel ratio sensor.

    Don’t use anything else but this one!!! Honda uses this exact sensor, they done like the cheaper ones. No code after a month, others were back within days. Save the time and headache and spend the extra $ for the right one

    My car wouldn't pass the emissions test! I took my car to Auto Zone for a scan! They told me it was the oxygen sensor! Now it runs fine and passed the test! I got the sensor recommended by the manufacturer!

    Turns out Sensor is faulty just like alternator i picked up a while ago smh AutoZone stuff always bad even if its OEM I got code p1163 smh bro NVM turns out issue was my mechanic added 2 spacer upstream and downstream should be only downstream But car is running good so far:) I still have issue I gotta install new spacers not old ones I had already paid for the product the o2 sensor spacers and was waiting for it. I even showed the cashier an example of what I wanted to buy. Instead of helping me, the cashier called the manager, who assumed I was trying to return something. I kept saying I wanted to buy the product, not return it, but they still didn’t give me what I paid for. I did pay them cash first for product I showed her my old one i couldnt find one she said she will bring one for me a new one smh. NATIONAL CITY IS NO BUENO SMH. So I ended up leaving with nothing—just gave AutoZone my money for free. SMH. Never again.

    208 miles since replacement, engine light is still off, no codes stored or pending via OBD2. I tried a cheaper ($40) sensor, which claimed to be equivalent, and that cheap one did not give correct sensor data, thus a code. If this one wasn't so expensive ($160) it would get more stars. 2004 Honda Civic VP
