Lifesaver!
This sensor was for my Hyundai Elantra 2004, I had my sensor light on for several months. I finally purchased this product and took less than 10 mins to install using the sensor socket (must have) purchased on Amazon as well, reset the battery and bamm!!! check engine light off! I was able to get it smogged and finally get my tags. I would recommend this product to anyone with the faulty oxygen sensor. The price was excellent compared to other sellers. Highly recommended!!!!

worked like a charm! check engine light turned off!!
fits 2006 hyundai Elantra limited This sensor made my check engine light go off!! The auto shops wanted to charge for all kinds of diagnostic over $190.00 which did not include parts. they also wanted to change the downstream sensor which did not show as faulty from the initial scan. So I did my internet homework and decided I could change this sensor myself. Which I did and saved $$$$ Amazon saved me at least up to $70.00 on this part. even with 1 day shipping. Autozone rented me the o2 sensor wrench. ($25.00) It was very difficult removing the old sensor. use plenty of WD-40!!! but once I put a breaker bar on my socket wrench I got it to budge!! talk about being happy!! and once I installed the new sensor and reset the battery and my check engine light did not come on I was really happy!! Thank you my favorite internet store Amazon!!!

Much cheaper than taking it to the shop
Picked this up a year and a half ago after my car's check engine light went on. After reviewing the codes with a code reader I figured the oxygen sensor was at fault. I reviewed compatible sensors and settled with this one. Sure enough, this has fixed it and the car has been running great ever since. No check engine lights either :)

Replacement O2 sensor on engine manifold in the front of the engine. Will need a special socket, easy to find at a Auto Parts shop or anywhere you can find used tools. Easy 10 minute job.

Se ve exactamente al original pero la parte donde viene los datos y marca del producto fue alterado y borrado así que no se aprecia si el producto corresponde al que están vendiendo, que pasasi lo instaló y sigue marcando falla en el scaner, podré regresar el producto?
