Factory Oxygen Sensor, 84-85 300ZX Turbo

Unfortunately, this item has been discontinued by Nissan. We now offer a replacement version of this item; see 11-3484-1 in Related Items below.

Description:
The Oxygen Sensor, located in the rear elbow on the turbocharger, works by detecting how much oxygen is in your exhaust. It then sends a signal to the computer, which uses that input (along with several other signals from various components) to make adjustments to the fuel flow into your engine. A bad O2 sensor can cause several issues, ranging from reduced fuel economy to a failed catalytic converter. Faulty O2 sensors are one of the most common causes of failed emissions tests. This is the genuine, original equipment (OEM) oxygen sensor. Sold individually; 1 required per car. Fits 84-85 turbo models only; see Related Items below for other years.
