New OEM Nissan Downstream (Rear) Oxygen Sensor for all '07+ 350Z, '08-2013 Infiniti G35 & G37, and '09-2013 Nissan 370Z models. 

Installed after the catalytic converters on the catalytic converter pipes, these sensors often prove to be extremely difficult to remove without destoying the threads when installing an aftermarket set of catalytic converters or test pipes.  These sensors are also referred to as an "Air-Fuel Ratio Sensor" by Nissan.

Sold individually, one sensor will fit either the Left or Right side of the vehicle.

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