Hey folks!

RE: my 2013 Subaru Outback P0031 Code (O2 sensor) Diagnosis

Mechanic recommends replacing all four sensors since I'm at 150k miles and he expects the others to fail soon enough.

Is that a good $500 investment in your estimation?

Here's the quote I received (incl. oil change, excl. timing chain leak est.) for $1,200 'round the San Francisco Bay. Thank you!

Eh, I wouldn't bother with all 4. It's not a "while you're in there" job (although he's not charging you any more labor..?). Can't hurt, but it is another ~$700 in parts (incl tax).

oh no no no no get the OE DENSO ones and cut that part cost in half

2x upstream DENSO $101 and 2x downstream $62 total $330
parts are the same for 10-14 cars and possibly up to 2019 cars

save your self the $125 and do it yourself easy access after you jack up front of car, support with jackstand and then remove front wheels. you can get from under car but wheel removal is easier
