OEM 2013-2018 Nissan Altima Upstream Oxygen (O2) Sensor for models equipped with the 2.5L QR25DE engine.
Installed before the catalytic converters on the exhaust manifold, these Sensors often prove to be extremely difficult to remove, without destroying 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.
Z1 Motorsports recommends the usage of an anti-seize compound on the threads of the oxygen sensor to make future servicing much easier.
Ensure proper fit and function with this genuine Nissan replacement part.
Sold Individually.
