Description
DENSO OXY1762 is a direct-fit upstream air/fuel ratio sensor for applicable Nissan 350Z models powered by the VQ35HR engine. It installs before the catalytic converter and measures exhaust oxygen content, providing the engine control unit with the feedback required to manage the air/fuel mixture.
This listing supplies one sensor. The VQ35HR uses two pre-catalytic sensors, so check which sensors require replacement before selecting the quantity.
