The kit includes two upstream (pre-catalytic converter) and two downstream (post-catalytic converter) sensors, each designed for plug-and-play installation where wiring and connector types match the original equipment.\u003c\/p\u003e\n\n\u003ch3\u003eHow will these sensors affect my vehicle's performance?\u003c\/h3\u003e\n\u003cp\u003eOxygen sensors provide the engine control module (ECM) with data on exhaust oxygen content so fuel mixture adjustments can be made. Replacing failing sensors restores accurate feedback for the ECM, helping it maintain proper air-fuel ratio and consistent engine behavior.
