## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit, no CEL
*by E***C on April 26, 2021*

Nice replacement for my defective upsteam O2 sensor. Using this in my 02 WRX and it works well. No check engine light, and no codes after using this for a couple weeks. Comes with anti-seize grease on the threads, and the plug fits perfectly with no issues at all. Great replacement product at a fraction of the OEM price.

### ⭐ supposed to last 100k miles right
*by G***È on November 14, 2024*

yeah no unlike the OEM denso sensor that last 100k miles this one didn't even last me a year....and that's the one I got to replace the one that crapped out after a few days. stay away from these these clown shoe wearing ....

### ⭐⭐⭐⭐⭐ Worked for 04 WRX
*by M***N on April 8, 2023*

A lot of cheap o2’s don’t work for the upstream spot on Subaru. I read some good reviews on this one so I decided to try it. Fits great and works great. Got rid of my Check engine light and got my AFR right. Save yourself 100+ bucks and buy this one.
