Oyeauto 4-Pack Oxygen (O2) Sensor Set
Keep your vehicle running efficiently and clear those “Check Engine” lights with this complete 4-pack of Oyeauto Oxygen Sensors. This set is designed to replace both the Upstream (Sensor 1) and Downstream (Sensor 2) units, providing a full refresh of your vehicle’s emissions monitoring system.
By accurately measuring the air-to-fuel ratio, these sensors help your engine’s computer optimize fuel consumption and minimize harmful pollutants.
Key Features
Complete System Coverage: Includes sensors for both upstream (pre-catalytic converter) and downstream (post-catalytic converter) positions.
Improved Fuel Economy: New sensors restore precise engine timing and fuel delivery, often resulting in better miles per gallon (MPG).
Enhanced Engine Performance: Reduces rough idling, engine hesitations, and misfires caused by faulty oxygen readings.
Direct Fit Design: Engineered with factory-style connectors for a “plug-and-play” installation—no wire splicing required.
Emission Compliance: Helps your vehicle pass smog and emissions testing by ensuring the catalytic converter is operating within spec.

Maintenance Tip
When replacing oxygen sensors, it is often best to replace them in pairs or full sets (like this 4-pack). Because sensors age at the same rate, replacing just one can sometimes lead to the engine computer detecting a mismatch with the older, slower sensors, triggering a new error code shortly after.
Pro Tip: Use a dedicated O2 sensor socket and apply a small amount of anti-seize lubricant to the threads (avoiding the sensor tip) to make future removals much easier.
