Replace Oxygen/Air Fuel Ratio Sensor
Hey there,

I am a newbie to the Subaru family. I bought my son an 02 Subaru WRX and we were just told that we need to replace the oxygen or the air fuel ratio sensor. Where can I find this part at a good price and the instructions on how to do this ourselves? It has a 2.0 DOHC engine.

Thank you family,
