I need to replace on of my O2 sensors, but I dont know if I need a cali or fed spec O2 sensor, how am I pose to tell the difference?

 

Open your hood...and look at the row of sensors right behind your radiator fill-cap.

If there is 4, you are Cali-spec. If there isn't 4, you aren't Cali-spec.

Also, I'm not completely sure about this, but I think only 99's can be Cali-spec. I'm a 99, dunno about you.

My car for reference:
