Well made. Came with anti-seize already applied to threads. Good cable length. Has been working fine for 2 months.

I bought two of these for my Hyundai Accent 2009 1.6 GLS, mainly to change the downstream sensor (located approximately right side of middle in line with the front tires, just past what looks to be a front muffler - weaved material- for those of you having trouble finding yours on the same type Accent).My old sensor threw a code, and by the time I got home (three hours) it had thrown another. P0138 and P0139. I decided on these because they were economical and one of the few products here that claimed a warranty - always a good sign compared to none.I struggled to get my old sensor off, but eventually it did. I got one of the special sensor 3/8 drive sockets, which caused some problems so I added the hose clamp trick to it to prevent it from stripping the sides anymore (YouTube it if you need to), and it worked like a charm after a week and a half of using penetrating oil on a regular basis.Like one of the other reviews about an Accent, which actually really convinced me to buy this product, I had a great experience after install. I only had to disconnect the battery for an hour and a half then start it up for the sensor to wake and stop throwing a code. The first time I started it up it was still there and I remembered that disconnecting the battery was supposed to reset it some.I’ve never changed an o2 sensor myself so I was quite happy it was plug and play. The clip went in like butter, and the problem getting the base in was totally the rust of the exhaust pipes and not this.Will be changing my upstream sensor in a couple weeks and will be using this product for that as well. :)

Fit fine on Hyundai

My Kia Rio 2010 had a check engine light on and for the codes we knew it was because of the oxygen sensor, so I boght this one but my mechanic had to figure out a creative way of screwing it because it didnt match, fortunately he is a very creative man and found the way, it solved the problem since now my kia doesnt have the check engine light. thanks!

After paying far too much and getting no answers from the repair shop, a friend suggested this product. It worked and saved me from another trip to the mechanic.
