This URD Rear O2 Simulator has been redesigned and is now a Plug-N-Play design and takes under a minute to install it.
This unit fits Toyota trucks that use the 3UR-FE 5.7L and the new 4.6L V8 engines to include, Tundra and Sequoia.

This device is very popular with customers that are installing Long Tube Headers on their 5.7L V8.

rear O2 sensor simulator is a device that conditions the signal from the rear O2 sensor and keeps that signal in the proper range the ECU is expecting to see from a properly functioning and healthy catalytic converter. Our device takes a slightly different approach than most of the other devices on the market. It is designed to work with the O2 sensor that is installed down stream of the catalytic converter. It does not replace it. The rear O2 sensor must remain in contact with the exhaust stream. This way the vehicle will looks stock. If you do a diagnostic hook up, you will see a proper signal from the rear O2 sensor and the signal will appear to be the same as if a properly functioning cat is in place.
