New OEM Infiniti Upstream (Front) Oxygen Sensor for '08-'10 Infiniti QX56 models.

Installed before the catalytic converters on the exhaust manifold, these sensors often prove to be difficult to remove without destroying the threads. These sensors are also referred to as a "Air-Fuel Ratio Sensor" by Nissan/Infiniti.

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:

• 2008-2010 Infiniti QX56
