S14 SR20DET O2 Sensor

Description

Brand new OEM SR20DET O2 Sensor for S13/S14/S15. These are OEM Nissan NTK O2 sensor. Changing out your old sensor to a new one usually would improve gas mileage. For S13 models, there’s 2 type of O2 sensors. There is the Large (FAT) (blacktop) and Small (Skinny) (Redtop) type, both have 3 wires. Images shown above are for the fat blacktop type. Either model will work on the engines, the only difference is the thread size.

NOTE: Main difference in S13 Fat type and S14 Fat type is the length of the wire. However that will not matter since end users will have to modify the SR20DET engine harness.
