New OEM Downstream (Rear) Oxygen Sensor for all '16+ Infiniti Q50 & Q60 models equipped with a 3.0t (VR30DDTT) drivetrain.

Installed after the turbo outlets in the secondary catalytic converters, these sensors often prove to be extremely difficult to remove without destroying the threads when installing an aftermarket downpipe or during routine maintenance.

Sold individually.

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