Review on Denso 234 9136 Oxygen Sensor by James Julien

I installed it on a 2013 Subaru Outback. Installation was easy with the right oxygen sensor removal tool. Although not a Subaru branded part, it was identical to the part I removed which was also a Denso branded part. The only difference was that the new sensor wire had two small plastic holders while the one I removed only had one. I removed the one closer to the harness connector since the one closer to the sensor was in the same location as the original one. The hole the clamp was supposed to go in was too big for the clamp on the sensor cable so I just used a small zip tie to secure it. It installed in a couple of weeks and works fine.
