OEM Downstream O2 Sensor for the Infiniti QX56/QX80. These sensors are also referred to as a "Heated O2 Sensor" by Infiniti. Installed after the catalytic converters on the exhaust, these sensors often prove to be extremely difficult to remove without destroying the threads when installing an aftermarket exhaust.

Z1 Motorsports recommends the usage of an anti-seize compound on the threads of the oxygen sensor to make future servicing much easier.
