New OEM Nissan Upstream (Front) Oxygen Sensor for all '11+ Infiniti G37 and '11-'14 Nissan 370Z models. 

Earlier Model VQ37VHR Front Oxygen Sensors can be found HERE.

Installed before the catalytic converters on the exhaust manifold, these sensors often prove to be extremely difficult to remove without destoying the threads when installing an aftermarket set of headers or forced induction setup.  These sensors are also referred to as a "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.

Fits:

  • 2011-2013 Infiniti G37
  • 2011-2014 Nissan 370Z
    • Up To 06/14

NOTE: This sensor only fits 370Z's up to 06/14 production. If you have a '14 model year 370Z produced AFTER 06/14 you need to purchase the O2 Sensor found HERE.
