O2 Sensor 95 Volvo 850 Turbo

I am about to install my 3rd O2 sensor in two years. This time I went for the
more expensive Bosch OEM sensor. Before I put it in does anyone know why the
damn things fail after 6 to 8 months.

If the car is running rich it will heat up the cat -O2 sensor will go out sooner. When the car is in "default" mode (when CEL is ON) it will run hot.
I went with OEM part ($160.00) from Eeuroparts.com because I did not want to think about it again. Some reported getting wrong sensor from AutoZone, etc.

I think that sensors are the parts that you want to replace with OEM stuff.
