Chevrolet Silverado 1500 Upstream Oxygen (O2) Sensor
$69.99
The upstream oxygen sensor measures unburned oxygen in the exhaust before the catalytic converter, letting the ECU fine-tune the air-fuel mixture. A worn sensor leads to poor fuel economy, rough idle, and potential catalytic converter damage.
This upstream O2 sensor is designed to fit the Chevrolet Silverado 1500 with the 5.3L V8 engine, matching the factory sensor location and wiring.
Built for reliable readings under sustained exhaust heat, it's a solid choice for restoring accurate fuel trim and passing emissions testing.
