i have a set of them, alls they do is plug in line with the rear set of 02 sensors, what they do is trick the pcm into thinking that the cats are working fine. the sensors arent there to read a/f ratio, thats what the first 2 right behind the manifolds are there for. the ones you are trying to trick are behind the cats. as far as i know, i dont think there are any draw backs to using them.
