Perfect fit, no CEL
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.

Worked for 04 WRX
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.

Good value
Bought for my 2005 Saab 92-x Aero. Part works as it should. Relatively easy install. It does not come with the clips you need to secure the sensor to the mount next to the engine block, so I just removed the airbox and secured it to the mount using zip ties. Overall, this is a good bang for the buck. OEM sensor is 200$ and this one was around 80. Works perfectly, removed check engine light for upstream o2.

Low cost alternative
Going off the other positive reviews and taking into consideration the unfortunate cost of the OE sensor, I took a chance on this little buddy for my 2003 WRX upstream o2. Hot dog, it worked ! The check engine light was on due to smashing the sensor during engine install. Once the battery was disconnected and the ECU reset no more CELs 🤙 for the price I'll probably buy a backup to keep habdy (just in case😉).

Non-functional
I tried to save some money over the OEM Denso unit, but after I installed it and the P0171 CEL remained, I had a mechanic test this unit and they determined it was not functioning correctly/putting out a signal. So I now paid for both the Denso and this one. Learn from me and skip this one. Suck it up and buy the OEM Denso.

Excellent for the price.
Solve my Cel without a trip to the mechanic or dealer. Easy to install with the right tools and so.e PB Blaster.

Gets rid of code doesn’t fix problem
Have a wrx that had a front 02 sensor problem. This sensor got rid of the code but when reading live data the sensor was going crazy reading full lean to full rich. Went to a name brand and car ran like new and easier to read when tuning
