what they do is replace the o sensor or sensors and trick the computer to think that the emissions is working right

i was on a police interceptor forum looking for answers about my car and this is what they told me to do just replace my 02 sensors with these

i would like to know has anyone ever used these installed these and if so are they worth the money or just a crazy shananigan to get money from ya
thanks

I've talked to a guy who was working on someone's car which had them. The only use for them is if you need to run the car without a catalytic converter. Otherwise stick with regular o2 sensors.

my car has no cats i cut them out and in place of them i put thrush tubes
thanks for the input

Then yeah, you'd want to get a simulator and replace the o2 sensor that would be post catalytic converter. I'm not entirely sure how they work, or if you need to replace all the o2 sensors, but the car probably wont run as good as it used to, and you'll have a check engine light on constantly complaining of the o2 sensor.

from the way the website explains and they explain it will get rid of that cel and code
as it is a thing to trick but yes i may invest in of them for my car and one for my truck as here recently my trucks been spitting the check engine light is on and its my o code but i know exactly why that one is due to the duals and the o not being in te middle of the pipes
