OEM Upstream O2 Sensor for the R35 GTR.

These sensors are also referred to as an "Air-Fuel Ratio Sensor" by Nissan. 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 downpipe.

Sold Individually.

Fits:
