Description Do you remove the O2 Sensor nut and leave your pipe exposed? This O2 Sensor Plug mates with the 8 x 1.5mm weld-in nut and allows removing the sensor after tuning. Without this plug, removing your oxygen sensor will result in an open hole in your exhaust. Looking for the O2 Sensor Nut so that you can mount your oxygen sensor? Computech Racing System’s O2 Sensor Nut allows you to mount an oxygen sensor to any exhaust that the nut can be welded onto. The 8 x 1.5mm Weld-In Nut is only for mounting the O2 sensor onto the exhaust pipe.
