The O2 sensor on my Forester has gone bad at 48,000 miles. Since I don't have the cash for the dealer to replace it I am going to try it myself. A couple of question though:
Can I get away with a generic replacement like a Universal Walker sensor part number 250-24000 or should I stick with the expensive OEM or Bosch part?
What is the best way to get to the sensors?
Any help would be great! Thanks! Chris
