Part #: 800-621
High quality single wire oxygen sensor for your 1979-83 Datsun 280ZX. This will be a Denso or Bosch OEM replacement. The oxygen sensor feeds info to the engine computer about the air/fuel ratio in the exhaust. If the oxygen sensor is not reading correctly, it can cause running and drivability issues with the fuel injection system. The oxygen sensor is located in the exhaust pipe close to the manifold and is fairly easy and quick to change out. Always be sure to inspect the wiring going to the oxygen sensor for anything being melted or cut.
