I threw the P0032 code the other day and really do not want to pay for a brand new sensor if I do not absolutely have too. Does anyone have a '03 that they're parting out? Thanks!

I see this your first forum post, so welcome to the forum from Oregon!

The stock one is a Denso.

Since you don't want to buy a new factory/OEM O2 sensor, some members have been happy with a direct fit Denso aftermarket O2 sensor purchased on Amazon.com. This isn't a recommendation.

The front O2 sensor (Air/Fuel sensor) is critical for correct engine operation, so I always buy factory/OEM for this part.

Thank you for the advice Bobby! I think I will go with the factory/OEM part. Is Subaru Genuine Parts dot com the best place to get them?

Factory/OEM is expensive, so if you want to save money, you'll have to shop around. Also give Jackie (SubaruPartsGirl), a supporting vendor here on the forum a call. Her direct number at Annapolis Subaru is (866) 509-3019. I live on the West cost & I get most of my factory/OEM parts from her.

This was the part number for the front O2 sensor on my son's '03 X:

• front Air/Fuel O2 sensor - SEN AY- AI - 22641AA280
