New OEM Upstream (Front) Oxygen Sensor for all '13+ Infiniti Q50 models equipped with a VQ35HR Hybrid drivetrain

Installed in the catalytic converters just after the exhaust manifold, these sensors often prove to be extremely difficult to remove without destroying the threads when installing an aftermarket set of high flow cats, test pipes, 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.
