OEM Downstream (Rear) Oxygen Sensor for all '16+ Infiniti Q50 & Q60 models equipped with a 2.0t drivetrain.

Installed in the catalytic converters just after the exhaust manifold, this sensor often proves to be extremely difficult to remove without destroying the threads during routine maintenance. 

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