I need to know what oxygen sensor would work in my 1989 325i other than the oem replacement part. I heard that ford has an oxygen sensor that would work in my car. If so, what model, year and type of engine. Or is there a universal O2 sensor out there? if so I can get a Bosh O2 sensors from work but I need to know a part number. The O2 sensor for my car is 89 dollars but I know that O2 sensors are pretty much the same. thanks BW.......
