The set includes two threaded, heated sensors with four-wire connectors and 560 mm harness length, packaged in protective boxes. Before ordering, confirm fitment using your vehicle details and the reference numbers provided to avoid ordering the wrong upstream sensor.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these downstream O2 sensors differ from upstream sensors?\u003c\/h3\u003e\n\u003cp\u003eDownstream sensors are mounted after the catalytic converter and primarily monitor converter efficiency rather than active air-fuel feedback. They are not interchangeable with upstream (pre-catalyst) sensors, which directly influence fuel trim.
