J-Replace - O2 Sensor (Fat Type) - Nissan SR20DET (OE-22690-50F03)

OE-replacement "fat" type O2 sensor (3-wire plug) — the Nissan OEM part is discontinued. Used on the S13 black top SR20DET and the S14 SR20DET. A used SR20 often comes with a worn sensor, so swapping it improves fuel economy.

Check your car: look at your existing sensor to confirm it is the fat type before ordering.
