OEM Upstream Oxygen Sensor for Nissan Frontier models equipped with the 3.8L (VQ38DD) powertrain.

This sensor is installed before the catalytic converter 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.

Sold Individually.

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