Hi everyone, I have a 2010 Legacy 2.5i base 6MT with about 90,000 miles and I got the christmas tree lights on the panel, after checking with an OBD2 reader It says my car has a problem with the O2 sensors and give me the code P0031, I also went to my local subaru service then they told me the same thing, both sensors upstream and downstream should be replaced; they are charging me 500 bucks for both sensors + install, is this ok?, on the other hand I checked DIY videos on youtube and I believe It would be possible for me to do it but I am unsure about the parts that I can buy and if they would match my car, also its my first time messing with any car beyond changing tires or battery.
Do someone knows if these parts can match my car?
Amazon: Denso 234-4445 Oxygen Sensor
Amazon: Denso 234 - 9097 A/F Sensor
Thanks in advance for your help.
